2011-05-16drm: Take lock around probes for drm_fb_helper_hotplug_eventChris Wilson1-4/+22
We need to hold the dev->mode_config.mutex whilst detecting the output status. But we also need to drop it for the call into drm_fb_helper_single_fb_probe(), which indirectly acquires the lock when attaching the fbcon. Failure to do so exposes a race with normal output probing. Detected by adding some warnings that the mutex is held to the backend detect routines: [ 17.772456] WARNING: at drivers/gpu/drm/i915/intel_crt.c:471 intel_crt_detect+0x3e/0x373 [i915]() [ 17.772458] Hardware name: Latitude E6400 [ 17.772460] Modules linked in: ....

2011-05-16drm/i915: Revert i915.semaphore=1 default from 47ae63e0Andy Lutomirski1-1/+1
My Q67 / i7-2600 box has rev09 Sandy Bridge graphics. It hangs instantly when GNOME loads and it hangs so hard the reset button doesn't work. Setting i915.semaphore=0 fixes it. Semaphores were disabled in a1656b9090f7008d2941c314f5a64724bea2ae37 in 2.6.38 and were re-enabled by commit 47ae63e0c2e5fdb582d471dc906eb29be94c732f Merge: c59a333 467cffb Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Mar 7 12:32:44 2011 +0000 Merge branch 'drm-intel-fixes' into drm-intel-next Apply the trivial conflicting regression fixes, but keep GPU semaphores enabled. Conflicts: drivers/gpu/drm/i915/i915_drv.h drivers/gpu/drm/i915/i915_gem_execbuffer.c (It's worth noting that the offending change is i915_drv.c, which is not a conflict.)

2011-05-16vga_switcheroo: don't toggle-switch devicesFlorian Mickler1-3/+3
If the requested device is already active, ignore the request. This restores the original behaviour of the interface. The change was probably an unintended side effect of commit 66b37c6777c4 vga_switcheroo: split switching into two stages which did not take into account to duplicate the !active check in the split-off stage2. Fix this by factoring that check out of stage1 into the debugfs_write routine.

2011-05-11drm/radeon/nouveau: fix build regression on alpha due to Xen changes.Dave Airlie2-4/+5
The Xen changes were using DMA_ERROR_CODE which isn't defined on a few platforms, however we reverted the Xen patch that caused use to try and use this code path earlier in 2.6.39 cycle, so for now lets just force the code to never take this path and allow it to build again on alpha. The proper long term answer is probably to store if the dma_addr has been assigned to alongside the dma_addr in the higher level code, though I think Thomas wanted to rewrite most of this anyways properly.

2011-05-09drm/nouveau: Fix a crash at card takedown for NV40 and older cardsJimmy Rentz2-2/+5
NV40 and older cards (pre NV50) reserve a vram bo for the vga memory at card init. This bo is then freed at card shutdown. The problem is that the ttm bo vram manager was already freed. So a crash occurs when the vga bo is freed. The fix is to free the vga bo prior to freeing the ttm bo vram manager. There might be other solutions but this seemed the simplest to me.

Given that the hardware may be left in a random condition by the BIOS, it is conceivable that we then attempt to clear the DP_PIPEB_SELECT bit without us ever enabling/attaching the DP encoder to a pipe.

Sometimes the i2c test in i2c_bit_add_bus fails if this happens we fail to register the i2c adapter and eventually fail to add the connector. If i2c fails, add the connector to the user can at least force it on. Note that some distros set i2c-algo-bit.bit_test to 1 by default which sometimes fails preventing the ddc i2c adapter from being added. The i2c adapter works even if the bit test fails, probably due to pre/post_xfer not getting called in the test_bit function. I have another patch to follow up on that.
