0e7ddf7eee drm/i915: Remove a bad BUG_ON in the fence management code.
This could be triggered by a gtt mapping fault on 965 that decides to
remove the fence from another object that happens to be active currently.
Since the other object doesn't rely on the fence reg for its execution, we
don't wait for it to finish.  We'll soon be not waiting on 915 most of the
time as well, so just drop the BUG_ON.

6c51d1cfa0 drm: don't associate _DRM_DRIVER maps with a master
A driver will use the _DRM_DRIVER map flag to indicate that it wants
to be responsible for removing the map itself, bypassing the DRM's
automagic cleanup code.

Since the multi-master changes this has been broken, resulting in some
drivers having their registers unmapped before it's finished with them.

c9fb15f60e drm: Hook up DPMS property handling in drm_crtc.c. Add drm_helper_connector_dpms.
Making the drm_crtc.c code recognize the DPMS property and invoke the
connector->dpms function doesn't remove any capability from the driver while
reducing code duplication.

That just highlighted the problem with the existing DPMS functions which
could turn off the connector, but failed to turn off any relevant crtcs. The
new drm_helper_connector_dpms function manages all of that, using the
drm_helper-specific crtc and encoder dpms functions, automatically computing
the appropriate DPMS level for each object in the system.

This fixes the current troubles in the i915 driver which left PLLs, pipes
and planes running while in DPMS_OFF mode or even while they were unused.

07f4f3e8a2 i915: Set object to gtt domain when faulting it back in
When a GEM object is evicted from the GTT we set it to the CPU domain,
as it might get swapped in and out or ever mmapped regularly.  If the
object is mmapped through the GTT it can still get evicted in this way
by other objects requiring GTT space.  When the GTT mapping is touched
again we fault it back into the GTT, but fail to set it back to the
GTT domain.  This means we fail to flush any cached CPU writes to the
pages backing the object which will then happen "eventually", typically
after we write to the page through the uncached GTT mapping.

[anholt: Note that userland does do a set_domain(GTT, GTT) when starting
to access the GTT mapping.  That covers getting the existing mapping of the
object synchronized if it's bound to the GTT.  But set_domain(GTT, GTT)
doesn't do anything if the object is currently unbound.  This fix covers the
transition to being bound for GTT mapping.]

cfa16a0de5 drm/i915: Apply a big hammer to 865 GEM object CPU cache flushing.
On the 865, but not the 855, the clflush we do appears to not actually make
it out to the hardware all the time.  An easy way to safely reproduce was
X -retro, which would show that some of the blits involved in drawing the
lovely root weave didn't make it out to the hardware.  Those blits are 32
bytes each, and 1-2 would be missing at various points around the screen.
Other experimentation (doing more clflush, doing more AGP chipset flush,
poking at some more device registers to maybe trigger more flushing) didn't
help.  krh came up with the wbinvd as a way to successfully get all those
blits to appear.

e76a16deb8 drm/i915: Fix tiling pitch handling on 8xx.
The pitch field is an exponent on pre-965, so we were rejecting buffers
on 8xx that we shouldn't have.  915 got lucky in that the largest legal
value happened to match (8KB / 512 = 0x10), but 8xx has a smaller tile width.
Additionally, we programmed that bad value into the register on 8xx, so the
only pitch that would work correctly was 4096 (512-1023 pixels), while others
would probably give bad rendering or hangs.

Previously, we would set the control bus switch before calls were made
to request EDID information over DDC.  But recently the DDC code started
doing multiple I2C transfers to get the EDID extensions as well.  This
tripped up SDVO, because the control bus switch is only in effect until
the next STOP after a START.  By doing our own algo, we can wrap each i2c
transaction on the DDC I2C bus with the control bus switch it requires.

ad5b2a6db3 drm/i915: Determine type before initialising connector
drm_connector_init sets both the connector type and the connector type_id
on the newly initialised connector.  As the connector type_id is coupled to
the connector type, the connector type cannot simply be modified on an
initialised connector.

This patch changes the order of operations on intel_sdvo_init so that the
type is determined before the connector is intialised.

This fixes a bug whereby the name card0-VGA-1 would be allocted to both a
CRT and an SDVO connector since the SDVO connector would be initialised
with type 'unknown' and hence have its type_id assigned from the wrong pool.

b674137755 drm: Round size of SHM maps to PAGE_SIZE
Currently, userspace can fail to obtain the SAREA mapping (among other
reasons) if it passes SAREA_MAX to drmAddMap without aligning it to the
page size. This breaks for example on PowerPC with 64K pages and radeon
despite the kernel radeon actually doing the right rouding in the first
place.

The way SAREA_MAX is defined with a bunch of ifdef's and duplicated
between libdrm and the X server is gross, ultimately it should be
retrieved by userspace from the kernel, but in the meantime, we have
plenty of existing userspace built with bad values that need to work.

This patch works around broken userspace by rounding the requested size
in drm_addmap_core() of any SHM map to the page size. Since the backing
memory for SHM maps is also allocated within addmap_core, there is no
danger of adjacent memory being exposed due to the increased map size.
The only side effect is that drivers that previously tried to create or
access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL),
will now succeed at the cost of a little bit more memory used if that
happens to be when the map is created.

8e7d2b2c6e drm/i915: allocate large pointer arrays with vmalloc
For awhile now, many of the GEM code paths have allocated page or
object arrays with the slab allocator.  This is nice and fast, but
won't work well if memory is fragmented, since the slab allocator works
with physically contiguous memory (i.e. order > 2 allocations are
likely to fail fairly early after booting and doing some work).

This patch works around the issue by falling back to vmalloc for
>PAGE_SIZE allocations.  This is ugly, but much less work than chaining
a bunch of pages together by hand (suprisingly there's not a bunch of
generic kernel helpers for this yet afaik).  vmalloc space is somewhat
precious on 32 bit kernels, but our allocations shouldn't be big enough
to cause problems, though they're routinely more than a page.

Note that this patch doesn't address the unchecked
alloc-based-on-ioctl-args in GEM; that needs to be fixed in a separate
patch.

Also, I've deliberately ignored the DRM's "area" junk.  I don't think
anyone actually uses it anymore and I'm hoping it gets ripped out soon.

[Updated: removed size arg to new free function.  We could unify the
free functions as well once the DRM mem tracking is ripped out.]

364b5b7b1d sysrq, intel_fb: fix sysrq g collision
Commit 79e539453b introduced a
regression where you cannot use sysrq 'g' to enter kgdb.  The solution
is to move the intel fb sysrq over to V for video instead of G for
graphics.  The SMP VOYAGER code to register for the sysrq-v is not
anywhere to be found in the mainline kernel, so the comments in the
code were cleaned up as well.

This patch also cleans up the sysrq definitions for kgdb to make it
generic for the kernel debugger, such that the sysrq 'g' can be used
in the future to enter a gdbstub or another kernel debugger.

425d244c86 drm/i915: ignore LVDS on intel graphics systems that lie about having it
There are a number of small form factor desktop systems with Intel mobile
graphics chips that lie and say they have an LVDS. With kernel mode-setting,
this becomes a problem, and makes native resolution boot go haywire -- for
example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to
have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080
display uses only the top left 1024x768, and auto-configured X will end
up only 1024x768 as well. With this change, graphical boot and X
both do 1920x1080 as expected.

Note that we're simply embracing and extending the early bail-out code
in place for the Mac Mini here. The xorg intel driver uses pci subsystem
device and vendor id for matching, while we're using dmi lookups here.

802c7eb646 drm/i915: sanity check IER at wait_request time
We might sleep here anyway so I hope an extra uncached read is ok to
add.

In #20896 we found that vbetool clobbers the IER.  In KMS mode this is
particularly bad since we don't set the interrupt regs late (in
EnterVT), so we'd fail to get *any* interrupts at all after X started
(since some distros have scripts that call vbetool at X startup
apparently).

So this patch checks IER at wait_request time, and re-enables
interrupts if it's been clobbered.  In a proper config this check
should never be triggered.

This is really a distro issue, but having a sanity check is nice, as
long as it doesn't have a real performance hit.

resume. It also should fix 945 performance reduction after resume which
would have disabled tiling without causing any visible effect.

049ef7e40f drm/i915: x86 always has writeq. Add I915_READ64 for symmetry.
i386 has inline code for writeq and readq, so just use those instead of ugly
macros which evaluate arguments multiple times.

c964b12942 drm/kms: don't try to shortcut drm mode set function
We have a drm_set_config which takes a crtc/encoder/mode setup,
and checks it to see if it can shortcut and just do a base setup,
or whether a complete mode setting is required.

b7f0ab460f ACPI, i915: Register ACPI video even when not modesetting
The ACPI video driver defers registration to the i915 driver if the
system supports opregion-mediated backlight control. This registration
was only being performed in the KMS case. Ensure it's done even if we
don't have modesetting enabled.
