Ben Skeggs 6c320fef58 drm/nouveau: pass flag to engine fini() method on suspend
It may not be necessary to fail in certain cases (such as failing to idle)
on module unload, whereas on suspend it's important to ensure a consistent
state can be restored on resume.

Ben Skeggs 12a30e267c drm/nv40/gr: rewrite/split context takedown functions
It's completely pointless to save the PGRAPH context when destroying a
channel, so don't bother.

This commit should also fix kernel.org bug 39422, where the DRM channel
state was incorrectly being saved because we left PGRAPH FIFO access
enabled while running the ctxprog.

Ben Skeggs e19b20bbd2 drm/nouveau: ignore connector type when deciding digital/analog on DVI-I
If the connector table is lying, which it often does on the boards of a
particular manufacturer, we may end up doing the wrong thing.  Listen
to the encoder table instead, it's more reliable.

Jon Mason 58b6542b50 DRM: remove drm_pci_device_is_pcie
drm_pci_device_is_pcie duplicates the funcationality of pci_is_pcie.
Convert callers of the former to the latter.  This has the side benefit
of removing an unnecessary search in the PCI configuration space due to
using a saved PCIe capability offset.

'drm/nouveau: rework vram init/fini ordering a little' changed
the order of instmem.init() and nouveau_mem_vram_init() which
resulted in using ramin_rsvd_vram before it was calculated and
failing to init any accel on pre-NV50 cards.

Since it's only used on <NV50 just calculate it where it's needed
and leave it as default 0 for NV50.

Ben Skeggs 24f246ac10 drm/nouveau: rework vram init/fini ordering a little
Commit "drm/nouveau: add some debug output if nouveau_mm busy at destroy time"
revealed an issue where vram mm takedown would actually fail due to there
still being nodes present, causing nouveau to leak a small amount of memory
on module unload.

This splits TTM/nouveau_mm a bit more cleanly and ensures nouveau_mm fini
isn't done until all gpuobjs are also destroyed.

Ben Skeggs 0411de8548 drm/nvc0/gr: import and use our own fuc by default
The ability to use NVIDIA's fuc has been retained *temporarily* in order
to better debug any issues that may be lingering in our initial attempt
at writing this ucode.  Once I'm fairly confident we're okay, it'll be
removed.

There's a number of things not implemented by this fuc currently, but
most of it is sets of state that our context setup would not have used
anyway.  No doubt we'll find out what they're for at some point, and
implement it if required.

This has been tested on 0xc0/0xc4 thus far, and from what I could tell
it worked as well as NVIDIA's.  It's also been tested on 0xc1, but even
with NVIDIA's fuc that chipset doesn't work correctly with nouveau yet.

0xc3/0xc8/0xce should in theory be supported too, but I don't have the
hardware to check that.

There's no doubt numerous bugs to squash yet, please report any!

Emil Velikov 2905544073 drm/nouveau/pm: Prevent overflow in nouveau_perf_init()
While parsing the perf table, there is no check if
the num of entries read from the vbios is less than
the currently allocated number.

In case of a buggy vbios this will cause overwriting
of kernel memory, causing aditional problems.

Add a simple check in order to prevent the case

When xorg state tracker wants to hide the cursor it calls set_cursor
with NULL buffer_handle and size=0x0, but nouveau refuses to hide it
because size is not 64x64... which is a bit odd. Both radeon and intel

Ben Skeggs 52eba8dd5e drm/nva3/clk: better pll calculation when no fractional fb div available
The core/mem/shader clocks don't support the fractional feedback divider,
causing our calculated clocks to be off by quite a lot in some cases.  To
solve this we will switch to a search-based algorithm when fN is NULL.

For my NVA8 at PL3, this actually generates identical cooefficients to
the binary driver.  Hopefully that's a good sign, and that does not
break VPLL calculation for someone..

Ben Skeggs 96d1fcf8b5 drm/nouveau/pm: translate ramcfg strap through ram restrict table
Hopefully this is how we're supposed to correctly handle when the RAMCFG
strap is above the number of entries in timing-related tables.

It's rather difficult to confirm without finding a configuration where
the ram restrict table doesn't map 8-15 back onto 0-7 anyway.  There's
not a single vbios in the repo which is configured differently..

In any case, this is probably still better than potentially reading
outside of the bounds of various tables..

Jimmy Rentz 976661093d drm/nouveau: Fix a crash at card takedown for NV40 and older cards
NV40 and older cards (pre NV50) reserve a vram bo for the vga memory at
card init. This bo is then freed at card shutdown.  The problem is that
the ttm bo vram manager was already freed. So a crash occurs when the
vga bo is freed. The fix is to free the vga bo prior to freeing the ttm
bo vram manager. There might be other solutions but this seemed the
simplest to me.

Emil Velikov 619d4f7e21 drm/nv50: improve nv50_pm_get_clock()
Many of the nv50 cards have their shader and/or memory pll
disabled at some stage.
This patch addresses those cases, so that the function
returns the correct frequency.

When the shader pll is disabled, the blob reports 2*core clock
Whereas for memory, the data stored in the vbios. This action
is incorrect as some vbioses store a clock value that is less
than the refference clock of the pll.

Thus we are reporting the reff_clk as it is the frequency the
pll actually operates

Dave Airlie 03a8066534 drm/radeon/nouveau: fix build regression on alpha due to Xen changes.
The Xen changes were using DMA_ERROR_CODE which isn't defined on a few
platforms, however we reverted the Xen patch that caused use to try and
use this code path earlier in 2.6.39 cycle, so for now lets just force
the code to never take this path and allow it to build again on alpha.

The proper long term answer is probably to store if the dma_addr has
been assigned to alongside the dma_addr in the higher level code,

Jimmy Rentz 7a7b94ad8c drm/nouveau: Fix a crash at card takedown for NV40 and older cards
NV40 and older cards (pre NV50) reserve a vram bo for the vga memory at
card init. This bo is then freed at card shutdown.  The problem is that
the ttm bo vram manager was already freed. So a crash occurs when the
vga bo is freed. The fix is to free the vga bo prior to freeing the ttm
bo vram manager. There might be other solutions but this seemed the
simplest to me.

however, as when we mapped the pages for the new bo the TLBs would've

Ben Skeggs db5c8e299a drm/nv50-nvc0: restrict memtype to those specified at creation time
Upcoming patches are going to enable full support for buffers that keep
a constant GPU virtual address whenever they're validated for use by
the GPU.

In order for this to work properly while keeping support for large pages,
we need to know if it's ever going to be possible for a buffer to end
up in GART, and if so, disable large pages for the buffer's VMA.

This is a new restriction that's not present in earlier kernel's, but
should not break userspace as the current code never attempts to validate
buffers into a memtype other than it was created with.

Torben Hohn ac751efa6a console: rename acquire/release_console_sem() to console_lock/unlock()
The -rt patches change the console_semaphore to console_mutex.  As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.

[akpm@linux-foundation.org: coding-style fixes]
[akpm@linux-foundation.org: make console_trylock return 1 on success, per Geert]

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

If you change the color depth via fbset or some other framebuffer aware
userland application struct fb_fix_screeninfo is not updated to this new

just pass in struct drm_framebuffer so in the future we could use more
fields. I'm hoping some day fix->smem* could be set here :-)

Current 3D driver expects this behaviour.  While this could be changed,
there's no compelling reason to reserve more than one subchannel for the
DRM.  If we ever need to use an object other then M2MF, we can just
re-bind subchannel 0 as required.

When hacking the libdrm for improvements, I triggered a kernel crash
related to the fact that the NOUVEAU_NOTIFIEROBJ_ALLOC ioctl calls
nouveau_channel_get with an unchecked channel index.
The patch ensures that the channel index is an unsigned and validates
its value in nouveau_channel_get.
