2013-08-04drm/radeon: allow selection of alignment in the sub-allocatorAlex Deucher
commit 6c4f978b357bc779c703fda1f200e9179623d3e9 upstream. There are cases where we need more than 4k alignment. No functional change with this commit. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-10-03Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds
Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked." Tons of conflicts mostly due to silly include line changes, but mostly mindless. A few other small semantic conflicts too, noted from Dave's pre-merged branch. * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (447 commits) drm/nv98/crypt: fix fuc build with latest envyas drm/nouveau/devinit: fixup various issues with subdev ctor/init ordering drm/nv41/vm: fix and enable use of "real" pciegart drm/nv44/vm: fix and enable use of "real" pciegart drm/nv04/dmaobj: fixup vm target handling in preparation for nv4x pcie drm/nouveau: store supported dma mask in vmmgr drm/nvc0/ibus: initial implementation of subdev drm/nouveau/therm: add support for fan-control modes drm/nouveau/hwmon: rename pwm0* to pmw1* to follow hwmon's rules drm/nouveau/therm: calculate the pwm divisor on nv50+ drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, faster drm/nouveau/therm: move thermal-related functions to the therm subdev drm/nouveau/bios: parse the pwm divisor from the perf table drm/nouveau/therm: use the EXTDEV table to detect i2c monitoring devices drm/nouveau/therm: rework thermal table parsing drm/nouveau/gpio: expose the PWM/TOGGLE parameter found in the gpio vbios table drm/nouveau: fix pm initialization order drm/nouveau/bios: check that fixed tvdac gpio data is valid before using it drm/nouveau: log channel debug/error messages from client object rather than drm client drm/nouveau: have drm debugging macros build on top of core macros ...

2012-10-02UAPI: (Scripted) Remove redundant DRM UAPI header #inclusions from drivers/gpu/.David Howells
Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.

2012-05-09drm/radeon: multiple ring allocator v3Christian König
A startover with a new idea for a multiple ring allocator. Should perform as well as a normal ring allocator as long as only one ring does somthing, but falls back to a more complex algorithm if more complex things start to happen. We store the last allocated bo in last, we always try to allocate after the last allocated bo. Principle is that in a linear GPU ring progression was is after last is the oldest bo we allocated and thus the first one that should no longer be in use by the GPU. If it's not the case we skip over the bo after last to the closest done bo if such one exist. If none exist and we are not asked to block we report failure to allocate. If we are asked to block we wait on all the oldest fence of all rings. We just wait for any of those fence to complete. v2: We need to be able to let hole point to the list_head, otherwise try free will never free the first allocation of the list. Also stop calling radeon_fence_signalled more than necessary. v3: Don't free allocations without considering them as a hole, otherwise we might lose holes. Also return ENOMEM instead of ENOENT when running out of fences to wait for. Limit the number of holes we try for each ring to 3.

2011-12-20drm/radeon: introduce a sub allocator and convert ib pool to it v4Jerome Glisse
Somewhat specializaed sub-allocator designed to perform sub-allocation for command buffer not only for current cs ioctl but for future command submission ioctl as well. Patch also convert current ib pool to use the sub allocator. Idea is that ib poll buffer can be share with other command buffer submission not having 64K granularity. v2 Harmonize pool handling and add suspend/resume callback to pin/unpin sa bo (tested on rv280, rv370, r420, rv515, rv610, rv710, redwood, cayman, rs480, rs690, rs880) v3 Simplify allocator v4 Fix radeon_ib_get error path to properly free fence Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
