Created attachment 10332 [details] [review] X.org log file with bad driver Created attachment 10333 [details] [review] X.org log with good driver Alex, any ideas? I'd noticed some freezes on switching back to the server, and although I haven't had time to track them down, that commit seems to fit the timeframe for me as well. Not sure. No freezes for me. Perhaps some cards don't like having the RADEON_LVDS_ON bit messed with? It seems some chips need it for proper LVDS blanking while others do not. Maybe it should be a driver option? I need to change RADEONDisableDisplays() to only touch LVDS on mobility chips; that may fix Andrew's issue (although if that were the case f19a6f7ee5bf4ec632e7813359f167599c08e823 should have broken things for him rather than c292fc64499ff4cc135c07deda99cf4169f8fef4). Andrew, I've just committed a patch (b72ff160f908bf3aa9f64705377e92d80360a4f7) to not touch LVDS on non-mobility radeons. Do you still get lockups with git master? I've just noticed one thing - lockups was not always after first switch from and back to X. Sometimes i need few switches back and forth - but 4 at max. I do new git bisect and result is: dcb64a4d3947e5a9fbda4b72e29a5b6102370f07 is first bad commit commit dcb64a4d3947e5a9fbda4b72e29a5b6102370f07 Author: Dave Airlie <airlied@linux.ie> Date: Sun Jun 3 17:10:49 2007 +1000 radeon: disable vbl interrupts when no 3d is running on a new enough drm with driver up to 4c61c0ee91a2ffeefce30972a584486f1df1d1ae i can switch VTs at least ten times without lockup.... will try more ... I moved RADEONDRISetVBlankInterrupt (pScrn, TRUE); right before RADEONDRIResume(pScrn->pScreen); in radeon_driver.c (function RADEONEnterVT) and i can jump to console and back to X without problem, even with spinning glxgears. Fix committed. Thanks for tracking it down. 92e65d5e0d6817ff4c9a08020a0a9b3a8c3c98b0 |
