2008-08-25drm: don't set the signal blocker on the master process.Dave Airlie1-8/+13
There is a problem with debugging the X server and gdb crashes in the xkb startup code. This avoids the problem by allowing the master process to get signals. It should be safe as the signal blocker is mainly so that you can Ctrl-Z a 3D application without locking up the whole box. Ctrl-Z the X server isn't something many people do.

2008-08-25drm: don't call the vblank tasklet with irqs disabled.Thomas Hellstrom2-15/+17
If a specific tasklet shares data with irq context, it needs to take a private irq-blocking spinlock within the tasklet itself. Signed-off-by: Dave Airlie <[email protected]>
2008-08-25r300: Fix cliprect emitNicolai Haehnle1-1/+4
This makes our handling of cliprects sane. drm_clip_rect always has exclusiv bottom-right corners, but the hardware expects inclusive bottom-right corner so we adjust this here. This complements Michel Daenzer's commit 57aea290e1e0a26d1e74df6cff777eb9f03 to Mesa. See also http://bugs.freedesktop.org/show_bug.cgi?id=16123 Signed-off-by: Dave Airlie <[email protected]>
2008-08-25drm/radeon: r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEXNicolai Haehnle1-16/+64
DRAW_INDEX writes a vertex count to VAP_VF_CNTL. Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.

2008-08-25radeon: fix some hard lockups on r3/4/500sJerome Glisse4-49/+130
This patch should fix hard lockup and convert them in softlockup (ie you can ssh the box but the gpu is busted and we are waiting in loop for it to come back to reason). Signed-off-by: Dave Airlie <[email protected]>
2008-07-30Fix off-by-one error in iov_iter_advance()Linus Torvalds1-1/+1
The iov_iter_advance() function would look at the iov->iov_len entry even though it might have iterated over the whole array, and iov was pointing past the end. This would cause DEBUG_PAGEALLOC to trigger a kernel page fault if the allocation was at the end of a page, and the next page was unallocated. The quick fix is to just change the order of the tests: check that there is any iovec data left before we check the iov entry itself. Thanks to Alexey Dobriyan for finding this case, and testing the fix.

2008-07-30romfs_readpage: don't report errors for pages beyond i_sizeLinus Torvalds1-14/+23
We zero-fill them like we are supposed to, and that's all fine. It's only an error if the 'romfs_copyfrom()' routine isn't able to fill the data that is supposed to be there. Most of the patch is really just re-organizing the code a bit, and using separate variables for the error value and for how much of the page we actually filled from the filesystem.
