2010-02-11vgaarb: fix incorrect dereference of userspace pointer.Andy Getzendanner
This patch corrects a userspace pointer dereference in the VGA arbiter in 2.6.32.1. copy_from_user() is used at line 822 to copy the contents of buf into kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.

2010-02-10drm/i915: Fix crash while aborting hibernationRafael J. Wysocki
Commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915) introduced the problem that if s2disk hibernation is aborted, the system will crash, because i915_pm_freeze() does nothing, while it should at least reverse some operations carried out by i915_suspend(). Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.

2010-02-10drm/i915: untangle page flip completionJesse Barnes
When a new page flip is requested, we need to both queue an unpin for the current framebuffer, and also increment the flip pending count on the newly submitted buffer. At flip finish time, we need to unpin the old fb and decrement the flip pending count on the new buffer. The old code was conflating the two, and led to hangs when new direct rendered apps were started, replacing the existing frame buffer. This patch splits out the buffers and prevents the hangs.

2010-02-10drm/i915: Increase fb alignment to 64kChris Wilson
An untiled framebuffer must be aligned to 64k. This is normally handled by intel_pin_and_fence_fb_obj(), but the intelfb_create() likes to be different and do the pinning itself. However, it aligns the buffer object incorrectly for pre-i965 chipsets causing a PGTBL_ERR when it is installed onto the output.

2010-02-10drm/i915: Update write_domains on active list after flush.Daniel Vetter
Before changing the status of a buffer with a pending write we will await upon a new flush for that buffer. So we can take advantage of any flushes posted whilst the buffer is active and pending processing by the GPU, by clearing its write_domain and updating its last_rendering_seqno -- thus saving a potential flush in deep queues and improves flushing behaviour upon eviction for both GTT space and fences. In order to reduce the time spent searching the active list for matching write_domains, we move those to a separate list whose elements are the buffers belong to the active/flushing list with pending writes. Orignal patch by Chris Wilson <chris@chris-wilson.co.uk>, forward-ported by me. In addition to better performance, this also fixes a real bug. Before this changes, i915_gem_evict_everything didn't work as advertised. When the gpu was actually busy and processing request, the flush and subsequent wait would not move active and dirty buffers to the inactive list, but just to the flushing list. Which triggered the BUG_ON at the end of this function. With the more tight dirty buffer tracking, all currently busy and dirty buffers get moved to the inactive list by one i915_gem_flush operation. I've left the BUG_ON I've used to prove this in there.

2010-02-10drm/i915: Rework DPLL calculation parameters for IronlakeZhenyu Wang
Got Ironlake DPLL parameter table, which reflects the hardware optimized values. So this one trys to list DPLL parameters for different output types, should potential fix clock issue seen on new Arrandale CPUs. This fixes DPLL setting failure on one 1920x1080 dual channel LVDS for Ironlake. Test has also been made on LVDS panels with smaller size and CRT/HDMI/DP ports for different monitors on their all supported modes. Update: - Change name of double LVDS to dual LVDS. - Fix SSC 120M reference clock to use the right range.

2010-02-10drm/nv50: avoid unloading pgraph context when ctxprog is runningMaarten Maathuis
- We need to disable pgraph fifo access before checking the current channel, otherwise we could still hit a running ctxprog. - The writes to 0x400500 are already handled by pgraph->fifo_access and are therefore redundant, moreover pgraph fifo access should not be reenabled before current context is set as invalid.

2010-02-10drm/nv50: align size of buffer object to the right boundaries.Maarten Maathuis
- In the current situation the padding that is added is dangerous to write to, userspace could potentially overwrite parts of another bo. - Depth and stencil buffers are supposed to be large enough in general so the waste of memory should be acceptable. - Alternatives are hiding the padding from users or splitting vram into 2 zones.
