2023-10-31drm/nouveau/imem/tu102-: prepare for GSP-RMBen Skeggs
- move suspend/resume paths to HW-specific code - allow (future) RM paths to be based on nv50_instmem Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230918202149.4343-15-skeggsb@gmail.com
2023-09-19drm/nouveau/imem: support allocations not preserved across suspendBen Skeggs
Will initially be used to tag some large grctx allocations which don't need to be saved, to speedup suspend/resume.

2017-11-02drm/nouveau/core/memory: add reference countingBen Skeggs
We need to be able to prevent memory from being freed while it's still mapped in a GPU's address-space. Will be used by upcoming MMU changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-11-02drm/nouveau/imem: allow nvkm_instobj to be directly embedded in backend objectBen Skeggs
This will eliminate a step through the call chain, and give backends more flexibility. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/memory: split info pointers from accessor pointersBen Skeggs
The accessor functions can change as a result of acquire()/release() calls, and are protected by any refcounting done there. Other functions must remain constant, as they can be called any time. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-11-25drm/nouveau/instmem: protect instobj list with a spinlockBen Skeggs
No locking is required for the traversal of this list, as it only happens during suspend/resume where nothing else can be executing. Fixes some of the issues noticed during parallel piglit runs. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-08-28drm/nouveau/imem: cosmetic changesBen Skeggs

2015-01-22drm/nouveau/instmem: namespace + nvidia gpu names (no binary change)Ben Skeggs
The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes)Ben Skeggs
The symlinks were annoying some people, and they're not used anywhere else in the kernel tree. The include directory structure has been changed so that symlinks aren't needed anymore. NVKM has been moved from core/ to nvkm/ to make it more obvious as to what the directory is for, and as some minor prep for when NVKM gets split out into its own module (virt) at a later date.
