Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

IB/mthca: Fix max_sge value returned by query_device The mthca driver returns the maximum number of scatter/gather entries returned by the firmware as the max_sge value when device properties are queried. However, the firmware also reports a limit on the maximum descriptor size allowed, and because mthca takes into account the worst case send request overhead when checking whether to allow a QP to be created, the largest number of scatter/gather entries that can be used with mthca may be limited by the maximum descriptor size rather than just by the actual s/g entry limit. This means that applications cannot actually create QPs with max_send_sge equal to the limit returned by ib_query_device(). Fix this by checking if the maximum descriptor size imposes a lower limit and if so returning that lower limit. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Disable tuning PCI read burst size The PCI spec recommends against drivers playing with a device's PCI read burst size, and says that systems software should configure it. And we actually have users that report that changing it from the default set by BIOS hurts performance and/or stability for them. On the other hand, the Mellanox Programmer's Reference Manual recommends turning it up all the way to the maximum value. Some tests conducted here in the lab do not show performance improvement from this tuning, but this might be just me. As a work-around, make this tuning an option, off by default (safe value), with an eye towards removing it completely one day if no one complains. Signed-off-by: Michael S.

IB/mthca: Add module parameter for number of MTTs per segment The current MTT allocator uses kmalloc() to allocate a buffer for its buddy allocator, and thus is limited in the amount of MTT segments that it can control. As a result, the size of memory that can be registered is limited too. This patch uses a module parameter to control the number of MTT entries that each segment represents, allowing more memory to be registered with the same number of segments.

IB/mthca: Fix max_sge value returned by query_device The mthca driver returns the maximum number of scatter/gather entries returned by the firmware as the max_sge value when device properties are queried. However, the firmware also reports a limit on the maximum descriptor size allowed, and because mthca takes into account the worst case send request overhead when checking whether to allow a QP to be created, the largest number of scatter/gather entries that can be used with mthca may be limited by the maximum descriptor size rather than just by the actual s/g entry limit. This means that applications cannot actually create QPs with max_send_sge equal to the limit returned by ib_query_device(). Fix this by checking if the maximum descriptor size imposes a lower limit and if so returning that lower limit. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Fix max_srq_sge returned by ib_query_device for Tavor devices The driver allocates SRQ WQEs size with a power of 2 size both for Tavor and for memfree. For Tavor, however, the hardware only requires the WQE size to be a multiple of 16, not a power of 2, and the max number of scatter-gather allowed is reported accordingly by the firmware (and this is the value currently returned by ib_query_device() and ibv_query_device()). If the max number of scatter/gather entries reported by the FW is used when creating an SRQ, the creation will fail for Tavor, since the required WQE size will be increased to the next power of 2, which turns out to be larger than the device permitted max WQE size (which is not a power of 2). This patch reduces the reported SRQ max wqe size so that it can be used successfully in creating an SRQ on Tavor HCAs.

IB: simplify static rate encoding Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

IB/mthca: Add IPoIB checksum offload support Arbel and Sinai devices support checksum generation and verification of TCP and UDP packets for UD IPoIB messages. This patch checks if the HCA supports this and sets the IB_DEVICE_UD_IP_CSUM capability flag if it does. It implements support for handling the IB_SEND_IP_CSUM send flag and setting the csum_ok field in receive work completions.

IB/mthca: Fix section mismatches Commit b3b30f5e ("IB/mthca: Recover from catastrophic errors") introduced some section mismatch breakage, because the error recovery code tears down and reinitializes the device, which calls into lots of code originally marked __devinit and __devexit from regular .text. Fix this by getting rid of these now-incorrect section markers. Reported by Randy Dunlap <randy.dunlap@oracle.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Avoid integer overflow when dealing with profile size mthca_make_profile() returns the size in bytes of the HCA context layout it creates, or a negative value if an error occurs. However, the return value is declared as u64 and the memfree initialization path casts this value to int to test if it is negative. This makes it think incorrectly than an error has occurred if the context size happens to be bigger than 2GB, since this turns into a negative int. Fix this by having mthca_make_profile() return an s64 and testing for an error by checking whether this 64-bit value itself is negative. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Avoid integer overflow when dealing with profile size mthca_make_profile() returns the size in bytes of the HCA context layout it creates, or a negative value if an error occurs. However, the return value is declared as u64 and the memfree initialization path casts this value to int to test if it is negative. This makes it think incorrectly than an error has occurred if the context size happens to be bigger than 2GB, since this turns into a negative int. Fix this by having mthca_make_profile() return an s64 and testing for an error by checking whether this 64-bit value itself is negative. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Fix section mismatches Commit b3b30f5e ("IB/mthca: Recover from catastrophic errors") introduced some section mismatch breakage, because the error recovery code tears down and reinitializes the device, which calls into lots of code originally marked __devinit and __devexit from regular .text. Fix this by getting rid of these now-incorrect section markers. Reported by Randy Dunlap <randy.dunlap@oracle.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Fix access to MTT and MPT tables on non-cache-coherent CPUs We allocate the MTT table with alloc_pages() and then do pci_map_sg(), so we must call pci_dma_sync_sg() after the CPU writes to the MTT table. This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

IB/mthca: Fix access to MTT and MPT tables on non-cache-coherent CPUs We allocate the MTT table with alloc_pages() and then do pci_map_sg(), so we must call pci_dma_sync_sg() after the CPU writes to the MTT table. This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

IB/mthca: Fix section mismatches Commit b3b30f5e ("IB/mthca: Recover from catastrophic errors") introduced some section mismatch breakage, because the error recovery code tears down and reinitializes the device, which calls into lots of code originally marked __devinit and __devexit from regular .text. Fix this by getting rid of these now-incorrect section markers. Reported by Randy Dunlap <randy.dunlap@oracle.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Fix access to MTT and MPT tables on non-cache-coherent CPUs We allocate the MTT table with alloc_pages() and then do pci_map_sg(), so we must call pci_dma_sync_sg() after the CPU writes to the MTT table. This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

IB/mthca: Fix access to MTT and MPT tables on non-cache-coherent CPUs We allocate the MTT table with alloc_pages() and then do pci_map_sg(), so we must call pci_dma_sync_sg() after the CPU writes to the MTT table. This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

IB/mthca: Fix section mismatches Commit b3b30f5e ("IB/mthca: Recover from catastrophic errors") introduced some section mismatch breakage, because the error recovery code tears down and reinitializes the device, which calls into lots of code originally marked __devinit and __devexit from regular .text. Fix this by getting rid of these now-incorrect section markers. Reported by Randy Dunlap <randy.dunlap@oracle.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

IB/mthca: Avoid integer overflow when dealing with profile size mthca_make_profile() returns the size in bytes of the HCA context layout it creates, or a negative value if an error occurs. However, the return value is declared as u64 and the memfree initialization path casts this value to int to test if it is negative. This makes it think incorrectly than an error has occurred if the context size happens to be bigger than 2GB, since this turns into a negative int. Fix this by having mthca_make_profile() return an s64 and testing for an error by checking whether this 64-bit value itself is negative. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Avoid integer overflow when dealing with profile size mthca_make_profile() returns the size in bytes of the HCA context layout it creates, or a negative value if an error occurs. However, the return value is declared as u64 and the memfree initialization path casts this value to int to test if it is negative. This makes it think incorrectly than an error has occurred if the context size happens to be bigger than 2GB, since this turns into a negative int. Fix this by having mthca_make_profile() return an s64 and testing for an error by checking whether this 64-bit value itself is negative. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Fix access to MTT and MPT tables on non-cache-coherent CPUs We allocate the MTT table with alloc_pages() and then do pci_map_sg(), so we must call pci_dma_sync_sg() after the CPU writes to the MTT table. This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

IB/mthca: Fix access to MTT and MPT tables on non-cache-coherent CPUs We allocate the MTT table with alloc_pages() and then do pci_map_sg(), so we must call pci_dma_sync_sg() after the CPU writes to the MTT table. This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

IB/mthca: Fix section mismatches Commit b3b30f5e ("IB/mthca: Recover from catastrophic errors") introduced some section mismatch breakage, because the error recovery code tears down and reinitializes the device, which calls into lots of code originally marked __devinit and __devexit from regular .text. Fix this by getting rid of these now-incorrect section markers. Reported by Randy Dunlap <randy.dunlap@oracle.com>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

IB/mthca: Stop returning separate error and status from FW commands Instead of having firmware command functions return an error and also a status, leading to code like: err = mthca_FW_COMMAND(..., &status); if (err) goto out; if (status) { err = -E...; goto out; } all over the place, just handle the FW status inside the FW command handling code (the way mlx4 does it), so we can simply write: err = mthca_FW_COMMAND(...); if (err) goto out; In addition to simplifying the source code, this also saves a healthy chunk of text: add/remove: 0/0 grow/shrink: 10/88 up/down: 510/-3357 (-2847) function old new delta static.trans_table 324 584 +260 mthca_cmd_poll 352 477 +125 mthca_cmd_wait 511 567 +56 mthca_table_put 213 240 +27 mthca_cleanup_db_tab 372 387 +15 __mthca_remove_one 314 323 +9 mthca_cleanup_user_db_tab 275 283 +8 __mthca_init_one 1738 1746 +8 mthca_cleanup 20 21 +1 mthca_MAD_IFC 1081 1082 +1 mthca_MGID_HASH 43 40 -3 mthca_MAP_ICM_AUX 23 20 -3 mthca_MAP_ICM 19 16 -3 mthca_MAP_FA 23 20 -3 mthca_READ_MGM 43 38 -5 mthca_QUERY_SRQ 43 38 -5 mthca_QUERY_QP 59 54 -5 mthca_HW2SW_SRQ 43 38 -5 mthca_HW2SW_MPT 60 55 -5 mthca_HW2SW_EQ 43 38 -5 mthca_HW2SW_CQ 43 38 -5 mthca_free_icm_table 120 114 -6 mthca_query_srq 214 206 -8 mthca_free_qp 662 654 -8 mthca_cmd 38 28 -10 mthca_alloc_db 1321 1311 -10 mthca_setup_hca 1067 1055 -12 mthca_WRITE_MTT 35 22 -13 mthca_WRITE_MGM 40 27 -13 mthca_UNMAP_ICM_AUX 36 23 -13 mthca_UNMAP_FA 36 23 -13 mthca_SYS_DIS 36 23 -13 mthca_SYNC_TPT 36 23 -13 mthca_SW2HW_SRQ 35 22 -13 mthca_SW2HW_MPT 35 22 -13 mthca_SW2HW_EQ 35 22 -13 mthca_SW2HW_CQ 35 22 -13 mthca_RUN_FW 36 23 -13 mthca_DISABLE_LAM 36 23 -13 mthca_CLOSE_IB 36 23 -13 mthca_CLOSE_HCA 38 25 -13 mthca_ARM_SRQ 39 26 -13 mthca_free_icms 178 164 -14 mthca_QUERY_DDR 389 375 -14 mthca_resize_cq 1063 1048 -15 mthca_unmap_eq_icm 123 107 -16 mthca_map_eq_icm 396 380 -16 mthca_cmd_box 90 74 -16 mthca_SET_IB 433 417 -16 mthca_RESIZE_CQ 369 353 -16 mthca_MAP_ICM_page 240 224 -16 mthca_MAP_EQ 183 167 -16 mthca_INIT_IB 473 457 -16 mthca_INIT_HCA 745 729 -16 mthca_map_user_db 816 798 -18 mthca_SYS_EN 157 139 -18 mthca_cleanup_qp_table 78 59 -19 mthca_cleanup_eq_table 168 149 -19 mthca_UNMAP_ICM 143 121 -22 mthca_modify_srq 172 149 -23 mthca_unmap_fmr 198 174 -24 mthca_query_qp 814 790 -24 mthca_query_pkey 343 319 -24 mthca_SET_ICM_SIZE 34 10 -24 mthca_QUERY_DEV_LIM 1870 1846 -24 mthca_map_cmd 1130 1105 -25 mthca_ENABLE_LAM 401 375 -26 mthca_modify_port 247 220 -27 mthca_query_device 884 850 -34 mthca_NOP 75 41 -34 mthca_table_get 287 249 -38 mthca_init_qp_table 333 293 -40 mthca_MODIFY_QP 348 308 -40 mthca_close_hca 131 89 -42 mthca_free_eq 435 390 -45 mthca_query_port 755 705 -50 mthca_free_cq 581 528 -53 mthca_alloc_icm_table 578 524 -54 mthca_multicast_attach 1041 986 -55 mthca_init_hca 326 271 -55 mthca_query_gid 487 431 -56 mthca_free_srq 524 468 -56 mthca_free_mr 168 111 -57 mthca_create_eq 1560 1501 -59 mthca_multicast_detach 790 728 -62 mthca_write_mtt 918 854 -64 mthca_register_device 1406 1342 -64 mthca_fmr_alloc 947 883 -64 mthca_mr_alloc 652 582 -70 mthca_process_mad 1242 1164 -78 mthca_dev_lim 910 830 -80 find_mgm 482 400 -82 mthca_modify_qp 3852 3753 -99 mthca_init_cq 1281 1181 -100 mthca_alloc_srq 1719 1610 -109 mthca_init_eq_table 1807 1679 -128 mthca_init_tavor 761 491 -270 mthca_init_arbel 2617 2098 -519 Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.de>

IB/mthca: Use pci_request_regions() Back in prehistoric (pre-git!) days, the kernel's MSI-X support did request_mem_region() on a device's MSI-X tables, which meant that a driver that enabled MSI-X couldn't use pci_request_regions() (since that would clash with the PCI layer's MSI-X request). However, that was removed (by me!) years ago, so mthca can just use pci_request_regions() and pci_release_regions() instead of its own much more complicated code that avoids requesting the MSI-X tables.

IB: Increase DMA max_segment_size on Mellanox hardware By default, each device is assumed to be able only handle 64 KB chunks during DMA. By giving the segment size a larger value, the block layer will coalesce more S/G entries together for SRP, allowing larger requests with the same sg_tablesize setting. The block layer is the only direct user of it, though a few IOMMU drivers reference it as well for their *_map_sg coalescing code. pci-gart_64 on x86, and a smattering on on sparc, powerpc, and ia64. Since other IB protocols could potentially see larger segments with this, let's check those: - iSER is fine, because you limit your maximum request size to 512 KB, so we'll never overrun the page vector in struct iser_page_vec (128 entries currently). It is independent of the DMA segment size, and handles multi-page segments already. - IPoIB is fine, as it maps each page individually, and doesn't use ib_dma_map_sg(). - RDS appears to do the right thing and has no dependencies on DMA segment size, but I don't claim to have done a complete audit. - NFSoRDMA and 9p are OK -- they do not use ib_dma_map_sg(), so they doesn't care about the coalescing. - Lustre's ko2iblnd does not care about coalescing -- it properly walks the returned sg list. This patch ups the value on Mellanox hardware to 1 GB, which matches reported firmware limits on mlx4.

IB/mthca: Don't allow userspace open while recovering from catastrophic error Userspace apps are supposed to release all ib device resources if they receive a fatal async event (IBV_EVENT_DEVICE_FATAL). However, the app has no way of knowing when the device has come back up, except to repeatedly attempt ibv_open_device() until it succeeds. However, currently there is no protection against the open succeeding while the device is in being removed following the fatal event. In this case, the open will succeed, but as a result the device waits in the middle of its removal until the new app releases its resources -- and the new app will not do so, since the open succeeded at a point following the fatal event generation. This patch adds an "active" flag to the device. The active flag is set to false (in the fatal event flow) before the "fatal" event is generated, so any subsequent ibv_dev_open() call to the device will fail until the device comes back up, thus preventing the above deadlock.

IB/mthca: Use pci_request_regions() Back in prehistoric (pre-git!) days, the kernel's MSI-X support did request_mem_region() on a device's MSI-X tables, which meant that a driver that enabled MSI-X couldn't use pci_request_regions() (since that would clash with the PCI layer's MSI-X request). However, that was removed (by me!) years ago, so mthca can just use pci_request_regions() and pci_release_regions() instead of its own much more complicated code that avoids requesting the MSI-X tables.

IB/mthca: Add module parameter for number of MTTs per segment The current MTT allocator uses kmalloc() to allocate a buffer for its buddy allocator, and thus is limited in the amount of MTT segments that it can control. As a result, the size of memory that can be registered is limited too. This patch uses a module parameter to control the number of MTT entries that each segment represents, allowing more memory to be registered with the same number of segments.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
