2017-11-02drm/nouveau: separate constant-va tracking from nvkm vma structureBen Skeggs1-4/+5
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau/fbcon: make use of drm_fb_helper.fbBen Skeggs1-1/+1
Transitional step towards properly refcounting the fbcon fb. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau/fbcon: make use of drm_fb_helper.devBen Skeggs1-4/+4
No need to store the pointer ourselves when it's already present in the base struct. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-30drm/nouveau/fbcon: fix font width not divisible by 8Mikulas Patocka1-1/+1
The patch f045f459d925 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses") tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the display when using fonts with width that is not divisiable by 8. The monochrome bitmap for each character is stored in memory by lines from top to bottom. Each line is padded to a full byte. For example, for 22x11 font, each line is padded to 16 bits, so each character is consuming 44 bytes total, that is 11 32-bit words. The patch f045f459d925 changed the logic to "dsize = ALIGN(image->width * image->height, 32) >> 5", that is just 8 words - this is incorrect and it causes display corruption. This patch adds the necesary padding of lines to 8 bytes. This patch should be backported to stable kernels where f045f459d925 was backported.

2016-05-20drm/nouveau: rename nouveau_drm.h to nouveau_drv.hBen Skeggs1-1/+1
Fixes out-of-tree build issue where uapi/drm/nouveau_drm.h gets picked up instead. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-08-28drm/nouveau/nvif: simplify and tidy library interfacesBen Skeggs1-1/+1
A variety of tweaks to the NVIF library interfaces, mostly ripping out things that turned out to be not so useful. - Removed refcounting from nvif_object, callers are expected to not be stupid instead. - nvif_client is directly reachable from anything derived from nvif_object, removing the need for heuristics to locate it - _new() versions of interfaces, that allocate memory for the object they construct, have been removed. The vast majority of callers used the embedded _init() interfaces. - No longer storing constructor arguments (and the data returned from nvkm) inside nvif_object, it's more or less unused and just wastes memory.

2015-07-27drm/nouveau/fbcon/gf100-: reduce RING_SPACE allocationIlia Mirkin1-1/+1
We only emit 58 words to the ring, not 60. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/nouveau: remove (most) hardcoded object handle usageBen Skeggs1-2/+2
The PFIFO<->EVO sync buffers will be fixed up later when inter-channel sync in general is improved. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nouveau: port remainder of drm code, and rip out compat layerBen Skeggs1-4/+4
v2: Ben Skeggs <bskeggs@redhat.com> - fill in nouveau_pm.dev to prevent oops - fix ppc issues (build + OF shadow) Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau: port all engines to new engine module formatBen Skeggs1-19/+12
This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination. It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz <marcin.slusarz@gmail.com> - fix find/replace bug in license header v3: Ben Skeggs <bskeggs@redhat.com> - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz <marcin.slusarz@gmail.com> - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs <bskeggs@redhat.com> - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs1-2/+2
Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
