drm/i915/gvt: Fix pipe A enable as default for vgpu
observed igt drv_module_reload test case failure on 4.15.0
rc2 kernel with panic due to no active pipe available.
the gpu will reset during unload/load and make pipe config reg
lost which can cause kernel panic issue happen.
this patch is to move pipe enabling to emulate_mointor_status_chagne
to handle vgpu reset case as well.

drm/i915/gvt: set max priority for gvt context
This is to workaround guest driver hang regression after
preemption enable that gvt hasn't enabled handling of that
for guest workload. So in effect this disables preemption
for gvt context now.

drm/i915/gvt: Don't mark vgpu context as inactive when preempted
We shouldn't mark inactive for vGPU context if preempted, which would still be re-scheduled later. So keep active state. Fixes: |

drm/i915/gvt: Limit read hw reg to active vgpu
mmio_read_from_hw() let vgpu could read hw reg, if vgpu's workload
is running on hw, things is good. Otherwise vgpu will get other
vgpu's reg val, it is unsafe.
This patch limit such hw access to active vgpu. If vgpu isn't
running on hw, the reg read of this vgpu will get the last active
val which saved at schedule_out.
v2: ring timestamp is walking continuously even if the ring is idle.
so read hw directly. (Zhenyu)

drm/i915/gvt: Export intel_gvt_render_mmio_to_ring_id()
Since many emulation logic needs to convert the offset of ring registers
into ring id, we export it for other caller which might need it.

drm/i915/gvt: Emulate PCI expansion ROM base address register
Our vGPU doesn't have a device ROM, we need follow the PCI spec to
report this info to drivers. Otherwise, we would see below errors.
Inspecting possible rom at 0xfe049000 (vd=8086:1912 bdf=00:10.0)
qemu-system-x86_64: vfio-pci: Cannot read device rom at 00000000-0000-0000-0000-000000000001
Device option ROM contents are probably invalid (check dmesg).
Skip option ROM probe with rombar=0, or load from file with romfile=No option rom signature (got 4860)
I will also send a improvement patch to PCI subsystem related to PCI ROM.
But no idea to omit below error, since no pattern to detect vbios shadow
without touch its content.
0000:00:10.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x0000

drm/i915/gvt: Correct ADDR_4K/2M/1G_MASK definition
For ADDR_4K_MASK, bit[45..12] should be 1, all other bits
should be 0. The current definition wrongly set bit[46] as 1
also. This path fixes this.
v2: Add commit message, fixes and cc stable.(Zhenyu)

drm/i915/gvt: Move request alloc to dispatch_workload path only
Previously the performance is improved through the workload auditing and shadowing ahead of vGPU scheduling, however, there is the case that more requests are allocated in submit_context before the previous request is added, the timeline will hold its seqno which is later. This patch is to move the request alloc to dispatch_workload function, where is the same place as request is added. It will fix the issue of kernel BUG for (timeline->seqno != request->fence.seqno) check when add_request. Fixes: |

drm/i915/gvt: Fix unsafe locking caused by spin_unlock_bh
The caller of shadow_context_status_change may disable irqs. So it is not
safe to use spin_unlock_bh in such context. Let's switch to irqsave version
for safety.

drm/i915: fix intel_backlight_device_register declaration
The alternative intel_backlight_device_register() definition apparently never got used, but I have now run into a case of i915 being compiled without CONFIG_BACKLIGHT_CLASS_DEVICE, resulting in a number of identical warnings: drivers/gpu/drm/i915/intel_drv.h:1739:12: error: 'intel_backlight_device_register' defined but not used [-Werror=unused-function] This marks the function as 'inline', which was surely the original intention here.

Merge tag 'drm-for-v4.15-part2' of git://people.freedesktop.org/~airlied/linux
Pull more drm updates from Dave Airlie:
"Fixes/cleanups for rc1, non-desktop flags for VR
- remove the MSM dt-bindings file Rob managed to push in the previous
pull.
- add a property/edid quirk to denote HMD devices, I had these
hanging around for a few weeks and Keith had done some work on
them, they are fairly self contained and small, and only affect
people using HTC Vive VR headsets so far.
- amdgpu, tegra, tilcdc, fsl fixes
- some imx-drm cleanups I missed, these seemed pretty small, and no
reason to hold off.
I have one TTM regression fix (fixes bochs-vga in qemu) sitting
locally awaiting review I'll probably send that in a separate pull
request tomorrow"

drm: add connector info/property for non-desktop displays [v2]
This adds the infrastructure needed to quirk displays using edid and to mark them a non-desktop. A non-desktop display is one which shouldn't normally be included as a part of a desktop environment.

treewide: setup_timer() -> timer_setup() (2 field)
This converts all remaining setup_timer() calls that use a nested field
to reach a struct timer_list. Coccinelle does not have an easy way to
match multiple fields, so a new script is needed to change the matches of
"&_E->_timer" into "&_E->_field1._timer" in all the rules.

treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.
Casting from unsigned long:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
setup_timer(&ptr->my_timer, my_callback, ptr);
and forced object casts:
void my_callback(struct something *ptr)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);
become:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
Direct function assignments:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
ptr->my_timer.function = my_callback;
have a temporary cast added, along with converting the args:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;
And finally, callbacks without a data assignment:
void my_callback(unsigned long data)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, 0);
have their argument renamed to verify they're unused during conversion:
void my_callback(struct timer_list *unused)
{
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
The conversion is done with the following Coccinelle script:
spatch --very-quiet --all-includes --include-headers \

treewide: init_timer() -> setup_timer()
This mechanically converts all remaining cases of ancient open-coded timer
setup with the old setup_timer() API, which is the first step in timer
conversions. This has no behavioral changes, since it ultimately just
changes the order of assignment to fields of struct timer_list when
finding variations of:
init_timer(&t);
f.function = timer_callback;
t.data = timer_callback_arg;
to be converted into:
setup_timer(&t, timer_callback, timer_callback_arg);
The conversion is done with the following Coccinelle script, which
is an improved version of scripts/cocci/api/setup_timer.cocci, in the
following ways:
- assignments-before-init_timer() cases
- limit the .data case removal to the specific struct timer_list instance
- handling calls by dereference (timer->field vs timer.field)

drm/tilcdc: Remove obsolete "ti,tilcdc,slave" dts binding support
This patch removes DRM_TILCDC_SLAVE_COMPAT option for supporting the obsolete "ti,tilcdc,slave" device tree binding. The new of_graph based binding - that is widely used in other drm driver too - has been supported since Linux v4.2. Maintaining the the backwards dts conversion code in the DRM_TILCDC_SLAVE_COMPAT has become a nuisance for the device/of development so the we decided to drop it after Linux v4.14, the 2017 LTS.

drm/tegra: sor: Reimplement pad clock
The current implementation of the pad clock isn't quite correct. This has the side-effect of being incompatible with the implementation for Tegra186 (provided by the BPMP) and therefore would require a massive change to the driver to cope with the differences. Instead, simply do what Tegra186 does and add some code to fallback to the old behaviour for existing device trees. Signed-off-by: Thierry Reding <treding@nvidia.com> |

It also contains support for all amdgpu supported GPUs (CIK, VI, Polaris), which has to be enabled. It is also a kms atomic modesetting compatible driver (unlike the current in-tree display code). I've kept it separate from drm-next because it may have some things that cause you to reject it. Background story: AMD have an internal team creating a shared OS codebase for display at hw bring up time using information from their hardware teams. This process doesn't lead to the most Linux friendly/looking code but we have worked together on cleaning a lot of it up and dealing with sparse/smatch/checkpatch, and having their team internally adhere to Linux coding standards. This tree is a complete history rebased since they started opening it, we decided not to squash it down as the history may have some value. Some of the commits therefore might not reach kernel standards, and we are steadily training people in AMD to better write commit msgs. There is a major bunch of generated bandwidth calculation and verification code that comes from their hardware team. On Vega and before this is float calculations, on Raven (DCN10) this is double based. They do the required things to do FP in the kernel, and I could understand this might raise some issues. Rewriting the bandwidth would be a major undertaken in reverification, it's non-trivial to work out if a display can handle the complete set of mode information thrown at it. Future story: There is a TODO list with this, and it address most of the remaining things that would be nice to refine/remove. The DCN10 code is still under development internally and they push out a lot of patches quite regularly and are supporting this code base with their display team. I think we've reached the point where keeping it out of tree is going to motivate distributions to start carrying the code, so I'd prefer we get it in tree. I think this code is slightly better than STAGING quality but not massively so, I'd really like to see that float/double magic gone and fixed point used, but AMD don't seem to think the accuracy and revalidation of the code is worth the effort" * tag 'drm-for-v4.15-amd-dc' of git://people.freedesktop.org/~airlied/linux: (1110 commits) drm/amd/display: fix MST link training fail division by 0 drm/amd/display: Fix formatting for null pointer dereference fix drm/amd/display: Remove dangling planes on dc commit state drm/amd/display: add flip_immediate to commit update for stream drm/amd/display: Miss register MST encoder cbs drm/amd/display: Fix warnings on S3 resume drm/amd/display: use num_timing_generator instead of pipe_count drm/amd/display: use configurable FBC option in dm drm/amd/display: fix AZ clock not enabled before program AZ endpoint amdgpu/dm: Don't use DRM_ERROR in amdgpu_dm_atomic_check amd/display: Fix potential null dereference in dce_calcs.c amdgpu/dm: Remove unused forward declaration drm/amdgpu: Remove unused dc_stream from amdgpu_crtc amdgpu/dc: Fix double unlock in amdgpu_dm_commit_planes amdgpu/dc: Fix missing null checks in amdgpu_dm.c amdgpu/dc: Fix potential null dereferences in amdgpu_dm.c amdgpu/dc: fix more indentation warnings amdgpu/dc: handle allocation failures in dc_commit_planes_to_stream. amdgpu/dc: fix indentation warning from smatch. amdgpu/dc: fix non-ansi function decls. ... |

Merge tag 'afs-next-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull AFS updates from David Howells:
"kAFS filesystem driver overhaul.
The major points of the overhaul are:
(1) Preliminary groundwork is laid for supporting network-namespacing
of kAFS. The remainder of the namespacing work requires some way
to pass namespace information to submounts triggered by an
automount. This requires something like the mount overhaul that's
in progress.
(2) sockaddr_rxrpc is used in preference to in_addr for holding
addresses internally and add support for talking to the YFS VL
server. With this, kAFS can do everything over IPv6 as well as
IPv4 if it's talking to servers that support it.
(3) Callback handling is overhauled to be generally passive rather
than active. 'Callbacks' are promises by the server to tell us
about data and metadata changes. Callbacks are now checked when
we next touch an inode rather than actively going and looking for
it where possible.
(4) File access permit caching is overhauled to store the caching
information per-inode rather than per-directory, shared over
subordinate files. Whilst older AFS servers only allow ACLs on
directories (shared to the files in that directory), newer AFS
servers break that restriction.
To improve memory usage and to make it easier to do mass-key
removal, permit combinations are cached and shared.
(5) Cell database management is overhauled to allow lighter locks to
be used and to make cell records autonomous state machines that
look after getting their own DNS records and cleaning themselves
up, in particular preventing races in acquiring and relinquishing
the fscache token for the cell.
(6) Volume caching is overhauled. The afs_vlocation record is got rid
of to simplify things and the superblock is now keyed on the cell
and the numeric volume ID only. The volume record is tied to a
superblock and normal superblock management is used to mediate
the lifetime of the volume fscache token.
(7) File server record caching is overhauled to make server records
independent of cells and volumes. A server can be in multiple
cells (in such a case, the administrator must make sure that the
VL services for all cells correctly reflect the volumes shared
between those cells).
Server records are now indexed using the UUID of the server
rather than the address since a server can have multiple
addresses.
(8) File server rotation is overhauled to handle VMOVED, VBUSY (and
similar), VOFFLINE and VNOVOL indications and to handle rotation
both of servers and addresses of those servers. The rotation will
also wait and retry if the server says it is busy.
(9) Data writeback is overhauled. Each inode no longer stores a list
of modified sections tagged with the key that authorised it in
favour of noting the modified region of a page in page->private
and storing a list of keys that made modifications in the inode.
This simplifies things and allows other keys to be used to
actually write to the server if a key that made a modification
becomes useless.
(10) Writable mmap() is implemented. This allows a kernel to be build
entirely on AFS.
Note that Pre AFS-3.4 servers are no longer supported, though this can
be added back if necessary (AFS-3.4 was released in 1998)"
