* drm/radeon/kms: properly set accel working flag and bailout when falseJerome Glisse2012-02-2213-8/+64
| | | | | | | | | | | | If accel is not working many subsystem such as the ib pool might not be initialized properly that can lead to segfault inside kernel when cs ioctl is call with non working acceleration. To avoid this make sure the accel working flag is false when an error in GPU startup happen and return EBUSY from cs ioctl if accel is not working.

| * drm/i915: do not enable RC6p on Sandy BridgeEugeni Dodonov2012-02-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With base on latest findings, RC6p seems to be respondible for RC6-related issues on Sandy Bridge platform. To work-around those issues, the previous solution was to completely disable RC6 on Sandy Bridge for the past few releases, even if plain RC6 was not giving any issues. What this patch does is preventing RC6p from being enabled on Sandy Bridge even if users enable RC6 via a kernel parameter. So it won't change the defaults in any way, but will ensure that if users do enable RC6 manually it won't break their machines by enabling this extra state. Proper fix for this (enabling specific RC6 states according to the GPU generation) were proposed for the -next kernel, but we are too late in the release process now to pick such changes.

This patch only supports 18bpp and 24bpp modes, which means that 10bpc modes will be computed incorrectly. Fixing that will require more extensive changes, and so must be addressed separately from this bugfix. intel_dp_link_required is called from intel_dp_mode_valid and intel_dp_mode_fixup. * intel_dp_mode_valid is called to list supported modes; in this case, the current crtc values cannot be relevant as the modes in question may never be selected. Thus, using intel_crtc->bpp is never right. * intel_dp_mode_fixup is called during mode setting, but it is run well before ironlake_crtc_mode_set is called to set intel_crtc->bpp, so using intel_crtc-bpp in this path can only ever get a stale value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Evergreen and NI blit copy was broken if the buffer maps to a rectangle whose one dimension is 16384 (max dimension allowed by these chips). In the mainline kernel, the problem is exposed only when buffers are very large (1G), but it's still a problem. The problem could be exposed for smaller buffers if anyone modifies the algorithm for rectangle construction in r600_blit_create_rect() (the reason why someone would modify that algorithm is to tune the performance of buffer moves). The root cause was in i2f() function which only operated on range between 0 and 16383. Fix this by extending the range of i2f() function to 0 to 32767. While at it improve the function so that the range can be easily extended in the future (if it becomes necessary), cleanup lines over 80 characters, and replace in-line comments with one strategic comment that explains the crux of the function. Credits to michel@daenzer.net for pointing out the root cause of the bug. v2: Fix I2F_MAX_INPUT constant definition goof and warn only once if input argument is out of range.

| | | | | | | | | | | | | | | | | | The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.

I've failed to take an odd interaction between my other cleanups and this reclaim_buffers patch into account and also failed to properly test it. Looks like there are more dragons and hidden trapdoors in the drm release path than actual lines of code. Until I get a clue, let's just revert this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | My forcewake spinlock patches have a functional conflict with Ben Widawsky's gen6 drpc support for debugfs. Result was a benign warning about trying to read an non-atomic variabla with atomic_read. Note that the entire check is racy anyway and purely informational. Also update it to reflect the forcewake voodoo changes, the kernel can now also hold onto a forcewake reference for longer times.
