There is an error in i915_read_blc_pwm_ctl, where the register values are not being copied correctly. BLC_PWM_CTL and BLC_PWM_CTL2 are getting mixed up. This patch fixes that so that saveBLC_PWM_CTL2 and not saveBLC_PWM_CTL is copied to the BLC_PWM_CTL2 register. Signed-off-by:

This patch enforces that the downclock clock source is the same as the preferred clock source for LVDS. This fixes a bug where the driver chooses a downclock clock source with a different P than the preferred mode clock source. This happened even if the preferred clock source implemented an acceptable rate for the downclock. The result of this bug is that downclock is disabled. Signed-off-by:

The "if (!p && !p->dev)" condition isn't right because || was intended instead of &&. But actually, "p" is the list cursor and so it's always non-NULL and we can just remove that bit. We can remove the another similar check as well. Signed-off-by:

So we have a few places where the drm drivers would like to sleep to be nice to the system, mainly in the modesetting paths, but we also have two cases were atomic modesetting must take place, panic writing and kernel debugger. So provide a central inline to determine if a sleep or delay should be used and use this in the intel and radeon drivers. v2: drop intel_drv.h MSLEEP macro, nobody uses it.

It would previously write basically random bits to PCI configuration space... Not very surprising that the GPU tended to stop responding completely. The resulting MCE even froze the whole machine sometimes. Now resetting the GPU after a lockup has at least a fighting chance of succeeding. Cc: stable@vger.kernel.org Signed-off-by:

drm/ttm/dma: Fix accounting error when calling ttm_mem_global_free_page and don't try to free freed pages. The code to figure out how many pages to shrink the pool ends up capping the 'count' at _manager->options.max_size - which is OK. Except that the 'count' is also used when accounting for how many pages are recycled - which we end up with the invalid values. This fixes it by using a different value for the amount of pages to shrink. On top of that we would free the cached page pool - which is nonsense as they are deleted from the pool - so there are no free pages in that pool.. Also we also missed the opportunity to batch the amount of pages to free (similar to how ttm_page_alloc.c does it). This reintroduces the code that was lost during rebasing. Reviewed-by:

Otherwise we are doing redundant work. Especially since the 'unbind' and 'unpopulate' have been merged and nouveau driver ends up calling it quite excessivly. On a GeForce 8600 GT with Gnome Shell (GNOME 3) we end up spending about 54% CPU time in __change_page_attr_set_clr checking the page flags.

Virtual address space are per drm client (opener of /dev/drm). Client are in charge of virtual address space, they need to map bo into it by calling DRM_RADEON_GEM_VA ioctl. First 16M of virtual address space is reserved by the kernel. Once using 2 level page table we should be able to have a small vram memory footprint for each pt (there would be one pt for all gart, one for all vram and then one first level for each virtual address space). Plan include using the sub allocator for a common vm page table area and using memcpy to copy vm page table in & out. Or use a gart object and copy things in & out using dma. v2: agd5f fixes: - Add vram base offset for vram pages. The GPU physical address of a vram page is FB_OFFSET + page offset. FB_OFFSET is 0 on discrete cards and the physical bus address of the stolen memory on integrated chips. - VM_CONTEXT1_PROTECTION_FAULT_DEFAULT_ADDR covers all vmid's >= 1 v3: agd5f: - integrate with the semaphore/multi-ring stuff v4: - rebase on top ttm dma & multi-ring stuff - userspace is now in charge of the address space - no more specific cs vm ioctl, instead cs ioctl has a new chunk v5: - properly handle mem == NULL case from move_notify callback - fix the vm cleanup path v6: - fix update of page table to only happen on valid mem placement v7: - add tlb flush for each vm context - add flags to define mapping property (readable, writeable, snooped) - make ring id implicit from ib->fence->ring, up to each asic callback to then do ring specific scheduling if vm ib scheduling function v8: - add query for ib limit and kernel reserved virtual space - rename vm->size to max_pfn (maximum number of page) - update gem_va ioctl to also allow unmap operation - bump kernel version to allow userspace to query for vm support v9: - rebuild page table only when bind and incrementaly depending on bo referenced by cs and that have been moved - allow virtual address space to grow - use sa allocator for vram page table - return invalid when querying vm limit on non cayman GPU - dump vm fault register on lockup v10: agd5f: - Move the vm schedule_ib callback to a standalone function, remove the callback and use the existing ib_execute callback for VM IBs. v11: - rebase on top of lastest Linus v12: agd5f: - remove spurious backslash - set IB vm_id to 0 in radeon_ib_get() v13: agd5f: - fix handling of RADEON_CHUNK_ID_FLAGS v14: - fix va destruction - fix suspend resume - forbid bo to have several different va in same vm v15: - rebase v16: - cleanup left over of vm init/fini v17: agd5f: - cs checker v18: agd5f: - reworks the CS ioctl to better support multiple rings and VM. Rather than adding a new chunk id for VM, just re-use the IB chunk id and add a new flags for VM mode. Also define additional dwords for the flags chunk id to define the what ring we want to use (gfx, compute, uvd, etc.) and the priority. v19: - fix cs fini in weird case of no ib - semi working flush fix for ni - rebase on top of sa allocator changes v20: agd5f: - further CS ioctl cleanups from Christian's comments v21: agd5f: - integrate CS checker improvements v22: agd5f: - final cleanups for release, only allow VM CS on cayman Signed-off-by:

drm_getclient, drm_getstats and drm_getmap (with a few minor adjustments) do not need global mutex, so fix that and make the said ioctls DRM_UNLOCKED. Details: drm_getclient: the only thing that should be protected here is dev->filelist and that is already protected everywhere with dev->struct_mutex. drm_getstats: there is no need for any mutex here because the loop runs through quasi-static (set at load time only) data, and the actual count access is done with atomic_read() drm_getmap already uses dev->struct_mutex to protect dev->maplist, which also used to protect the same structure everywhere else except at three places: * drm_getsarea, which doesn't grab *any* mutex before touching dev->maplist (so no drm_global_mutex doesn't help here either; different issue for a different patch). However, drivers seem to call it only at initialization time so it probably doesn't matter * drm_master_destroy, which is called from drm_master_put, which in turn is protected with dev->struct_mutex everywhere else in drm module, so we are good here too. * drm_getsareactx, which releases the dev->struct_mutex too early, but this patch includes the fix for that. v2: * incorporate comments received from Daniel Vetter * include the (long) explanation above to make it clear what we are doing (and why), also at Daniel Vetter's request * tighten up mutex grab/release locations to only encompass real critical sections, rather than some random code around them Signed-off-by:Ilija Hadzic <ihadzic@research.bell-labs.com> Reviewed-by:
