In 3.7-rc4, when starting X with the integrated GPU and suspending the discrete GPU, after one or more 32-bit applications are used (eg Skype) and X is stopped, we hit a panic. Prevent this by testing if the fini function is valid.

...I'm seeing significant graphical corruption and later unrecoverable GPU lockup, accompanied by thousands of ILLEGAL_MTHD or related kernel messages [1]. I see similar issues on 3.12 also. Is there any debugging or testing I can do to help diagnose this? Many thanks, Daniel --- [1] http://quora.org/nouveau-dmesg.txt http://quora.org/nouveau-Xorg.0.log -- Daniel J Blueman

On 3.8-rc2 with lockdep enabled and dual-GPU setup (Macbook Pro Retina), I see two releated lock inversion issues with the EFI framebuffer, leading to possible deadlock: when X takes over from the EFI framebuffer [1] and when nouveau releases the framebuffer when being vgaswitcherood [2]. Let me know if you'd like any testing or analysis when I can get the time. Many thanks, Daniel ---

Hi all, when I call the llvm.memcpy/memmove/memset.* intrinsics, typically I have to pass in valid (non-dangling, non-NULL pointers) of the given alignment. However, to what extent to these rules apply when the count is 0? Concretely (for any variant of the three aforementioned intrinsics): Is it UB to call them on a dangling pointer when count is 0? On a pointer of less than the given
