drm: Hook up DPMS property handling in drm_crtc.c. Add drm_helper_connector_dpms.

2009-06-03T23:32:12Z

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.

drm/i915: allocate large pointer arrays with vmalloc

2009-05-19T17:07:14Z

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.] fd.o bug #20152 (part 1/3) Signed-off-by: Jesse Barnes Signed-off-by: Eric Anholt

drm/i915: Add new GET_PIPE_FROM_CRTC_ID ioctl.

2009-05-14T23:00:32Z

This allows userlevel code to discover the pipe number corresponding to a given CRTC ID. This is necessary for doing pipe-specific operations such as waiting for vblank on a given CRTC. Failure to use the right pipe mapping can result in GPU hangs, or at least failure to actually sync to vblank.

drm/i915: add support for G41 chipset

2009-04-22T00:22:53Z

This had been delayed for some time due to failure to work on the one piece of G41 hardware we had, and lack of success reports from anybody else. Current hardware appears to be OK. Signed-off-by: Zhenyu Wang [anholt: hand-applied due to conflicts with IGD patches] Signed-off-by: Eric Anholt

Support the Intel 854 Chipset in fbdev. We test and use the patch on a Thomson IP1101 IPTV-Box. On the VGA-Port we get a normal signal.

drm/i915: Allow tiling of objects with bit 17 swizzling by the CPU.

2009-04-08T17:50:57Z

Save the bit 17 state of the pages when freeing the page list, and reswizzle them if necessary when rebinding the pages (in case they were swapped out). Since we have userland with expectations that the swizzle enums let it pread and pwrite contents accurately, we can't expose a new swizzle enum for bit 17 (which it would have to GTT map to handle), so we handle it down in pread and pwrite by swizzling the copy when bit 17 of the page address is set.
