* core: rename subclass.base to subclass.superclassBen Skeggs2015-01-101-1/+0
| | | | | | | | Makes things a bit more readable. This is specially important now as upcoming commits are going to be gradually removing the use of macros for down-casts, in favour of compile-time checking. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm: wake up the card if necessary during gem callbacksBen Skeggs2014-12-221-5/+30
| | | | | | | | | | The failure paths if we fail to wake the card are less than desirable, but there's not really a graceful way to handle this case currently. I'll keep this situation in mind when I get to fixing other vm-related issues. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm: fix missing return statement in nouveau_ttm_tt_unpopulateAlexandre Courbot2014-12-221-1/+3
| | | | | | | | | | nouveau_ttm_tt_unpopulate() is supposed to return right after calling ttm_dma_unpopulate() in the case of a coherent buffer. The return statement was omitted, leading to the pages being unmapped twice. Fix this. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* kms/nv50: drop requirement that framebuffer bos be contig up-frontBen Skeggs2014-12-021-5/+0
| | | | | | We'll move them at pin() time if necessary. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* kms/nv50: directly use cursor image from userspace bufferBen Skeggs2014-12-022-49/+32
| | | | | | | | | Preparation for transition to planes, which use framebuffers for the cursor image. We've always done copies from the userspace buffer up until now for legacy reasons, there's no good reason to do so on the chipsets this code covers. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* kms: when pinning display-related buffers, force contig vramBen Skeggs2014-12-022-7/+7

* drm: teach nouveau_bo_pin() how to force a contig vram allocationBen Skeggs2014-12-0213-27/+52
| | | | | | | | | | | We have the ability to move buffers around in the kernel if necessary, and should probably use it rather than failing if userspace passes us a non-contig buffer for a plane. The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere initial placement hint once all the relevant paths have been updated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* bios: add parsing of BIT M(v2) +0x03 tableBen Skeggs2014-12-023-0/+3
| | | | | | | | | We only support one kind of matching here (ramcfg strap), but it appears alternate methods are possible. I wrote a tool to scan our vbios repo for other types, but did not see any used. Hopefully this means there aren't any in the wild that will now break. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm: synchronize BOs when requiredAlexandre Courbot2014-12-023-0/+56
| | | | | | | | | | | | | | | On architectures for which access to GPU memory is non-coherent, caches need to be flushed and invalidated explicitly when BO control changes between CPU and GPU. This patch adds buffer synchronization functions which invokes the correct API (PCI or DMA) to ensure synchronization is effective. Based on the TTM DMA cache helper patches by Lucas Stach.

* drm: allocate GPFIFOs and fences coherentlyAlexandre Courbot2014-12-022-3/+3
| | | | | | | | | Specify TTM_PL_FLAG_UNCACHED when allocating GPFIFOs and fences to allow them to be safely accessed by the kernel without being synced on non-coherent architectures. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm: implement explicitly coherent BOsAlexandre Courbot2014-12-022-8/+73
| | | | | | | | | | | | | | | Allow nouveau_bo_new() to recognize the TTM_PL_FLAG_UNCACHED flag, which means that we want the allocated BO to be perfectly coherent between the CPU and GPU. This is useful on non-coherent architectures for which we do not want to manually sync some rarely-accessed buffers: typically, fences and pushbuffers. A TTM BO allocated with the TTM_PL_FLAG_UNCACHED on a non-coherent architecture will be populated using the DMA API, and accesses to it performed using the coherent mapping performed by dma_alloc_coherent().

* bios: split out shadow methodsBen Skeggs2014-12-0210-0/+16
| | | | | | | | | | | We're about to need to be able to fetch additional chunks of data beyond the primary bios image, which makes fetching a lot more complicated. This splits out the verious shadowing routines to be nothing more than very dumb "fetch this much data from this offset" routines, and leaves the logic of what and how much to fetch in common code.

| | | | | | | | | | | | | | | | | Commit 1dce6264045cd23e9c07574ed0bb31c7dce9354f introduced a regression spotted on several G94 (FDObz #85160).

* gpio: rename g92 class to g94Emil Velikov2014-10-023-2/+2
| | | | | | | | | | | | | | | | | nv92 hardware has only 16 interrupt lines, while nv94 and later has 32. Accessing 0xe0c{0,4} registers on nv92 can lead to incorrect PDISP setup.
