In order to prevent the most obvious issue of the low of the vblank interrupt (stuttering compositing that only updates when the mouse is moving) is to install a PM QoS request to prevent low c-states whilst the GPU is active.

If the vbios has not run, several of these will need to be setup. So we need to check that the LVDS sync polarity is correctly configured per any available modelines (e.g. EDID) and adjust if not, issuing a warning as we do.

So we can't just clobber the existing state everytime we set a mode, we need to take into account what the other CRTCs are doing at the time. Doing so fixes an issue where you'd lose the LVDS display at boot if you had an LVDS+DP config.

This causes wrong backlight values in certain conditions. Instead of adding tricky code handling badly documented and rare corner cases, don't handle combination mode specially at all. This way PCI_LBPC is never touched and weird things shouldn't happen. If combination mode is enabled, then the only downside is that changing the brightness has a greater granularity (the LBPC value), but LBPC is at most 254 and the maximum is in the thousands, so this is no real functional loss. A potential problem with not handling combined mode is that a brightness of max * PCI_LBPC is not bright enough. However, this is very unlikely because from the documentation LBPC seems to act as a scaling factor and doesn't look like it's supposed to be changed after boot. The value at boot should always result in a bright enough screen. IMPORTANT: However, although usually the above is true, it may not be when people ran an older (2.6.37) kernel which messed up the LBPC register, and they are unlucky enough to have a BIOS that saves and restores the LBPC value. Then a good kernel may seem to not work: Max brightness isn't bright enough. If this happens people should boot back into the old kernel, set brightness to the maximum, and then reboot. After that everything should be fine. For more information see the below links.

Probably inherited from i81x which had 2kb tiles (which naturally fit an even-number-of-tile-rows scheme to fit onto 4kb pages). There is no other mention of this in any docs (also not in the Intel internal documention according to Chris Wilson). Problem manifests itself in corruptions in the second half of the last tile row (if the bo has an odd number of tiles). Which can only happen with relaxed tiling (introduced in a00b10c360b35d6431a9). So reject set_tiling calls that don't satisfy this constrain to prevent broken userspace from causing havoc. While at it, also check the size for newer chipsets.

The symptoms are that 4 bytes at the beginning of a page get overwritten by zeroes. The address of the corruption varies when rebooting the machine, but stays constant while it's running (so it's possible to repeatedly write some data and then corrupt it again by plugging the cable). Further investigation revealed that the corrupted address is (dev_priv->status_page_dmah->busaddr & 0xffffffff), ie. the beginning of the hardware status page of the i965 graphics card, cut to 32 bits. So it seems that for some memory access, the hardware uses only 32 bit addressing. If the hardware status page is located >4GB, this corrupts unrelated memory.

(I'm optimistic that disabling GPU semaphores is simply hiding another bug by the latency and side-effects of the additional device interaction it introduces...) However, use of semaphores is a massive performance improvement... Only as long as the system remains stable. Enable at your peril.
