That indirection mess can now go. Add a dummy i81x gtt_driver to avoid a NULL pointer check. Signed-off-by:

Like before, but now with the added bonus of being able to kill quite a bit of no-longer userful code (the old dmar support stuff). Signed-off-by:

Beef up the generic version to support dmar. Otherwise like for the i830. v2: Don't try to DMA remap on resume for already remapped pages. Signed-off-by:

Daniel Vetter authored
Well, not all too generic because it does not yet support dmar. Add a new function check_flags to ensure that non-gem code does not try to screw us over. v2: Beautify i830_check_flags with an idea from Chris Wilson. Signed-off-by:

Only used to remap the scratch page. Now that intel-gtt does this itself, kill the support code. Cc: Dave Airlie <airlied@linux.ie> Signed-off-by:

intel-gtt.c now handles the scratch page itself, so drop all that was just there to support it. Signed-off-by:

Like for i830. intel_i9xx_configure is now unused, so kill it. Signed-off-by:

And put it to use in the gtt configuration code that writes the scratch page addr in all gtt ptes. This makes intel_i830_configure generic, hence rename it to intel_fake_agp_configure. Signed-off-by:

Daniel Vetter authored
The intel gtt fake agp driver is the only agp driver to use dma address remapping. So it makes sense to fold this code back into the only user (and thus reduce the reliance on the agp code). This patch does the first step by initializing (and remapping) the scratch page in a new function intel_gtt_setup_scratch_page. Unfortunately intel_gtt_cleanup had to move to avoid a forward declaration. The new scratch page is not yet used, though. v2: Refactor out scratch page teardown. Suggested by Chris Wilson on irc. This makes it clear what's going on and results in a nice symmetry between setup and teardown. Signed-off-by:

Keep a list of pinned objects and display it via debugfs. Now all objects that exist in the GTT are always tracked on one of the active, flushing, inactive or pinned lists. Signed-off-by: -

Track if the gpu requires the fence for the execution of a batch buffer and so only wait upon the retirement of the object's last rendering seqno if the fence is in use by the GPU. Signed-off-by: -

Documentation explicitly mentions that the ring registers are designed to have the same offsets relative to a base registers. Use this to fight the code beaurocratic in intel_ringbuffer.c. No code changes in this patch, just the new definitions. Signed-off-by:

Daniel Vetter authored
This looks like a copy-paste remnant from the i810. All the regs that are actually used are already defined somewhere else in i915_reg.h! Signed-off-by:

As noted by Zhenyu, we can now simply replace the existing advance hook by calling the new set_tail function pointer directly. Signed-off-by: -

This is prepared for video codec ring buffer on Sandybridge. It is needed to read/write more than one register to move the tail pointer of the video codec ring on Sandybridge. Signed-off-by:

Previously we only tidied up the active bo lists for chipsets were we would attempt to reset the GPU. However, this action is necessary for the system to continue and reclaim the dead bo for all chipsets. Pointed out, in passing, by Owain Ainsworth. Signed-off-by: -

Clear the GPU read domain for the inactive objects on a reset so that they are correctly invalidated on reuse. Signed-off-by: -

Owain Ainsworth noticed that the reset code failed to clear the flushing list leaving the driver in an inconsistent state following a hung GPU. Signed-off-by: -

When flushing the GPU domains,we emit a flush on *both* rings, even though they share a unified cache. Only emit the flush on the currently active ring. Signed-off-by: -

Change the semantics to retire any buffer older than the current seqno rather than repeatedly calling calling the function to retire the buffer at the head of the list matching the request seqno. Whilst this should have no semantic impact on the implementation, Daniel was wondering if there was a bug where we might miss a retirement and so end up with a continually growing active list.

On more recent chipsets, restoring the display is not as simple as writing a few registers, so force a full modeset of the current configuration in order to retrain the display link. Signed-off-by: -

The graphics domains are listed as GRDOM in the documentation, and the GDRST PCI config register (0xc0) is only valid on I965 and GM45. Newer chips (like Sandy Bridge) have a different GDRST. Signed-off-by:
