* drm/radeon: fix deferred page-flip detection logic on Avivo-based ASICsFelix Kuehling2012-02-29
| | | | | | | | | | | | | | | | | | | | | | | | This fixes page-flip-related flickering observed on Iconia Tab W500. The update_pending status returned by radeon_page_flip is very accurate on Avivo-based ASICs when vpos is negative. Experiments were conducted on several ASIC generations ranging from RS690 to Cayman where the page flip was artificially timed to occur at a specific vpos. With negative vpos, overriding update_pending always lead to flickering. The same experiment on RV380 and RV410 showed that update_pending is not accurate with negative vpos. In most cases update_pending == 1 is returned although the flip would complete before the start of the next frame. Therefore I left the behaviour unchanged for pre-AVIVO ASICs for performance reasons, although this may result in flickering in rare cases. This change also makes the logic a little easier to understand.

| * drm: move pci bus master enable into driver.Dave Airlie2012-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current enabling of bus mastering in the drm midlayer allows a large race condition under kexec. When a kexec'ed kernel re-enables bus mastering for the GPU, previously setup dma blocks may cause writes to random pieces of memory. On radeon the writeback mechanism can cause these sorts of issues. This patch doesn't fix the problem, but it moves the bus master enable under the individual drivers control so they can move enabling it until later in their load cycle and close the race. Fix for radeon kms driver will be in a follow-up patch. Signed-off-by: Dave Airlie <airlied@redhat.com>

| * drm/kms: Make i2c buses fasterJean Delvare2012-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A udelay value of 20 leads to an I2C bus running at only 25 kbps. I2C devices can typically operate faster than this, 50 kbps should be fine for all devices (and compliant devices can always stretch the clock if needed.) FWIW, the vast majority of framebuffer drivers set udelay to 10 already. So set it to 10 in DRM drivers too, this will make EDID block reads faster. We might even lower the udelay value later if no problem is reported.

* drm/radeon/kms/blit: fix blit copy for very large buffersIlija Hadzic2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Evergreen and NI blit copy was broken if the buffer maps to a rectangle whose one dimension is 16384 (max dimension allowed by these chips). In the mainline kernel, the problem is exposed only when buffers are very large (1G), but it's still a problem. The problem could be exposed for smaller buffers if anyone modifies the algorithm for rectangle construction in r600_blit_create_rect() (the reason why someone would modify that algorithm is to tune the performance of buffer moves). The root cause was in i2f() function which only operated on range between 0 and 16383. Fix this by extending the range of i2f() function to 0 to 32767. While at it improve the function so that the range can be easily extended in the future (if it becomes necessary), cleanup lines over 80 characters, and replace in-line comments with one strategic comment that explains the crux of the function. Credits to michel@daenzer.net for pointing out the root cause of the bug. v2: Fix I2F_MAX_INPUT constant definition goof and warn only once if input argument is out of range.
