2010-01-11drm/nouveau: initialise DMA tracking parameters earlierBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-11drm/nouveau: use dma.max rather than pushbuf size for checking GET validityBen Skeggs
Some upcoming G80 DMA changes will depend on this, but it's split out for bisectibility just in case it causes some unexpected issues. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-01-11drm/nouveau: Fix null deref in nouveau_fence_emit due to deleted fenceLuca Barbieri
Currently Nouveau will unvalidate all buffers if it is forced to wait on one, and then start revalidating from the beginning. While doing so, it destroys the operation fence, causing nouveau_fence_emit to crash. This patch fixes this bug by taking the fence object out of validate_op and creating it just before emit. The fence pointer is initialized to 0 and unref'ed unconditionally. In addition to fixing the bug, this prevents its reintroduction and simplifies the code.

2010-01-11drm/nv50: prevent a possible ctxprog hangBen Skeggs
The below is mainly an educated guess at what's going on, docs would sure be handy... NVIDIA? :P It appears it's possible for a ctxprog to run even while a GPU exception is pending. The GF8 and up ctxprogs appear to have a small snippet of code which detects this, and stalls the ctxprog until it's been handled, which essentially looks like: if (r2 & 0x00008000) { r0 |= 0x80000000; while (r0 & 0x80000000) {} } I don't know of any way that flag would get cleared unless the driver intervenes (and indeed, in the cases I've seen the hang, nothing steps in to automagically clear it for us). This patch causes the driver to clear the flag during the PGRAPH IRQ handler. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-11drm/nouveau: have ttm's fault handler called directlyBen Skeggs
There's no good reason for us to have our own anymore, this is left over from an early port to these TTM interfaces. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-01-11drm/nouveau: create function for "dealing" with gpu lockupMarcin Slusarz
It's mostly a cleanup, but in nv50_fbcon_accel_init gpu lockup message was printed, but HWACCEL_DISBALED flag was not set. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-01-11drm/nouveau: fix handling of fbcon colours in 8bppBen Skeggs
Depending on the visual, the colours handed to us in fillrect() can either be an actual colour, or an index into the pseudo-palette. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-11drm/nv04: Context switching fixes.Francisco Jerez
Signed-off-by: Francisco Jerez <currojerez@riseup.net>
2010-01-11drm/nouveau: Use the software object for fencing.Francisco Jerez
This should avoid a race condition on nv0x, if we're doing it with actual PGRAPH objects and a there's a fence within the FIFO DMA fetch area when a context switch kicks in. In that case we get an ILLEGAL_MTHD interrupt as expected, but the values in PGRAPH_TRAPPED_ADDR aren't calculated correctly and they're almost useless (e.g. you can see ILLEGAL_MTHDs for the now inactive channel, with a wrong offset/data pair). Signed-off-by: Francisco Jerez <currojerez@riseup.net>
2010-01-11drm/nouveau: Allocate a per-channel instance of NV_SW.Francisco Jerez
It will be useful for various synchronization purposes, mostly stolen from "[PATCH] drm/nv50: synchronize user channel after buffer object move on kernel channel" by Maarten Maathuis. Signed-off-by: Francisco Jerez <currojerez@riseup.net>
2010-01-11drm/nv50: make the blocksize depend on vram sizeMaarten Maathuis
- This should be better than what we have now. - I'm less sure about the non power of two path. Signed-off-by: Maarten Maathuis <madman2003@gmail.com>
2010-01-11drm/nouveau: better alignment of bo sizes and use roundup instead of ALIGNMaarten Maathuis
- Aligning to block size should ensure that the extra size is enough. - Using roundup, because not all sizes are powers of two. Signed-off-by: Maarten Maathuis <madman2003@gmail.com>

2010-01-11drm/kms/fb: check for depth changes from userspace for resizing.Dave Airlie
If userspace (plymouth in this case) asks for a deeper depth, refuse it as well due to lack of resizing. This fixes an issue since < 32MB cards went to 8bpp and plymouth crashes on startup. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-01-11drm: Keep disabled outputs disabled after suspend / resumeDavid John
With the current DRM code, an output that has been powered off from userspace will automatically power back on when resuming from suspend. This patch fixes this behaviour.

2010-01-07drm: remove address mask param for drm_pci_alloc()Zhenyu Wang
drm_pci_alloc() has input of address mask for setting pci dma mask on the device, which should be properly setup by drm driver. And leave it as a param for drm_pci_alloc() would cause confusion or mistake would corrupt the correct dma mask setting, as seen on intel hw which set wrong dma mask for hw status page.
