* drm/nouveau: debugfs: implement DRM GPU VA debugfsDanilo Krummrich2023-08-041-0/+39

* drm: convert .debugfs_init() hook to return void.Wambui Karuga2020-03-181-4/+2
| | | | | | | | | | | | | | | | | | | | | As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

* drm/nouveau: make nouveau_drm_debugfs_init() return 0Wambui Karuga2020-03-181-12/+8
| | | | | | | | | | | | | | | | | | Since 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), there is no need to ever check for the the return value of debugfs_create_file() and drm_debugfs_create_files(). Therefore, remove unnecessary checks and error handling in nouveau_drm_debugfs_init() and have the function return 0 directly. v2: have nouveau_drm_debugfs_init() return 0 instead of void so as not to introduce any build warnings to enable individual patch compilation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | PFIFO on G80 and up has a new mode where the main ring buffer is simply a ring of pointers to indirect buffers containing the actual command/data packets. In order to be able to implement index buffers in the 3D driver we need to be able to submit data-only push buffers right after the cmd packet header, which is only possible using the new command submission method. This commit doesn't make it possible to implement index buffers yet, some userspace interface changes will be required, but it does allow for testing/debugging of the hardware-side support in the meantime.

* drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs2009-12-111-0/+155
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver. This driver requires firmware files not available in this kernel tree, interested parties can find them via the nouveau project git archive. This driver is reverse engineered, and is in no way supported by nVidia. Support for nearly the complete range of nvidia hw from nv04->g80 (nv50) is available, and the kms driver should support driving nearly all output types (displayport is under development still) along with supporting suspend/resume. This work is all from the upstream nouveau project found at nouveau.freedesktop.org.
