2012-04-22drm/radeon: fix load detect on rn50 with hardcoded EDIDs.Dave Airlie
commit a09d431f344d854e4fe9cfac44f78cb8202f3eb7 upstream. When the force changes went in back in 3.3.0, we ended up returning disconnected in the !force case, and the connected in when forced, as it hit the hardcoded check. Fix it so all exits go via the hardcoded check and stop spurious modesets on platforms with hardcoded EDIDs.

2012-04-22drm/radeon/kms: fix the regression of DVI connector checkTakashi Iwai

The check of the encoder type in the commit [e00e8b5e: drm/radeon/kms: fix analog load detection on DVI-I connectors] is obviously wrong, and it's the culprit of the regression on my workstation with DVI-analog connection resulting in the blank output.

2012-02-02drm/radeon/kms/blit: fix blit copy for very large buffersIlija Hadzic
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. Edit the comment a little bit to avoid some linguistic confusion and make it look better in general.

2012-02-01drm/radeon: Set DESKTOP_HEIGHT register to the framebuffer (not mode) height.Michel Dänzer
The value of this register is transferred to the V_COUNTER register at the beginning of vertical blank. V_COUNTER is the reference for VLINE waits and goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout, so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the beginning of vertical blank, and VLINE waits excluding the whole scanout area could never finish (possibly only if VIEWPORT_Y_START is larger than the length of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer height should prevent this for any kind of VLINE wait. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=45329 .
