This commit adds a KMS driver for the Tegra20 SoC. This includes basic support for host1x and the two display controllers found on the Tegra20 SoC. Each display controller can drive a separate RGB/LVDS output. Signed-off-by:

We link every DRM "file_priv" to a "drm_master" structure. Currently, the drmSetMaster() call returns 0 when there is _any_ active master associated with the "drm_master" structure of the calling "file_priv". This means, that after drmSetMaster() we are not guaranteed to be DRM-Master and might not be able to perform mode-setting. A way to reproduce this is by starting weston with the DRM backend from within an X-console (eg., xterm). Because the xserver's "drm_master" is currently active, weston is assigned to the same master but is inactive because its VT is inactive and the xserver is still active. But when "fake-activating" weston, it calls drmSetMaster(). With current behavior this returns "0/success" and weston thinks that it is DRM-Master, even though it is not (as the xserver is still DRM-Master). Expected behavior would be drmSetMaster() to return -EINVAL, because the xserver is still DRM-Master. This patch changes exactly that. The only way this bogus behavior would be useful is for clients to check whether their associated "drm_master" is currently the active DRM-Master. But this logic fails if no DRM-Master is currently active at all. Because then the client itself would become DRM-Master (if it is root) and this makes this whole thing useles. Also note that the second "if-condition": file_priv->minor->master != file_priv->master is always true and can be skipped. Signed-off-by:

Whoops. This was fixed previously, but not sure how it got lost. It's not needed for -fixes or stable because at the moment drm_i915_file_private is way bigger than i915_hw_context (by 120 bytes on my 64b build). Signed-off-by:

After the rework, intel_set_mode() became a little better behaved in restoring the current mode if we failed to apply the requested modeline. However, the failure path for load-detect would clobber the existing state, leading to an oops during BIOS takeover on older machines. Signed-off-by:

This allows us to map the PTEs WC. I've not done thorough testing or performance measurements with this patch, but it should be decent. This is based on a patch from Jesse with the original commit message > I've only lightly tested this so far, but the corruption seems to be > gone if I write the GFX_FLSH_CNTL reg after binding an object. This > register should control the TLB for the system agent, which is what CPU > mapped objects will go through. It has been updated for the new AGP-less code by me, and included with it is feedback from the original patch. v2: Updated to reflect paranoia on pte updates/register posting reads. Signed-off-by:

This bug existed in the old code, but was easier to fix here in the rework. Unfortunately gen7 doesn't have a nice way to figure out the size and we must use a lookup table. As Jesse pointed out, there is some confusion in the docs about these definitions. We're picking the one which seems more accurate, but we really aren't certain. Signed-off-by:

As a quick hack we make the old intel_gtt structure mutable so we can fool a bunch of the existing code which depends on elements in that data structure. We can/should try to remove this in a subsequent patch. This should preserve the old gtt init behavior which upon writing these patches seems incorrect. The next patch will fix these things. The one exception is VLV which doesn't have the preserved flush control write behavior. Since we want to do that for all GEN6+ stuff, we'll handle that in a later patch. Mainstream VLV support doesn't actually exist yet anyway. v2: Update the comment to remove the "voodoo" Check that the last pte written matches what we readback v3: actually kill cache_level_to_agp_type since most of the flags will disappear in an upcoming patch v4: v3 was actually not what we wanted (Daniel) Make the ggtt bind assertions better and stricter (Chris) Fix some uncaught errors at gtt init (Chris) Some other random stuff that Chris wanted v5: check for i==0 in gen6_ggtt_bind_object to shut up gcc (Ben) Signed-off-by:

Communicating via the mailbox registers with the PCU can take quite awhile.

The console lock can be contended, so rather than prevent other drivers after us from being held up, queue the console suspend into the global work queue that can happen anytime. I've measured this to take around 200ms on my T420. Combined with the ring freq/turbo change, we should save almost 1/2 a second on resume. v2: use console_trylock() to try to resume the console immediately (Chris) Signed-off-by:

dev_priv has grown way too big, and grouping memebers into substructs and moving them out of line helps re-gain some overview. Unfortunatley I couldn't just call the substruct save and drop the prefix, since that will make most member names clash with registers #defines.
