2017-11-03drm/nouveau/bios: make const arrays hwsq_signature and edid_sig staticColin Ian King
Don't populate arrays hwsq_signature and edid_sig on the stack but instead make them static. Makes the object code smaller by over 190 bytes: Before: text data bss dec hex filename 35676 3312 64 39052 988c nouveau_bios.o After: text data bss dec hex filename 35319 3472 64 38855 97c7 nouveau_bios.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-11-02drm/nouveau: queue delayed unmapping of VMAs on client workqueueBen Skeggs
VMAs are about to not take references on the VMM they belong to, which means more care is required when handling delayed unmapping. Queuing it on the client workqueue ensures all pending VMA unmaps will have completed before the VMM is destroyed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-11-02drm/nouveau: check kind validity against mmu objectBen Skeggs
This is already handled in the top-level gem_new() ioctl in another manner, but this will be removed in a future commit. Ideally we'd not need to check up-front at all, and let the VMM code handle error checking, but there are paths in the current BO management code where this isn't possible due to map() not always being called during BO creation, and map() calls not being allowed to fail during buffer migration.

2017-11-02drm/nouveau/mmu: implement new vmm frontendBen Skeggs
These are the new priviledged interfaces to the VMM backends, and expose some functionality that wasn't previously available. It's now possible to allocate a chunk of address-space (even all of it), without causing page tables to be allocated up-front, and then map into it at arbitrary locations. This is the basic primitive used to support features such as sparse mapping, or to allow userspace control over its own address-space, or HMM (where the GPU driver isn't in control of the address-space layout). Rather than being tied to a subtle combination of memory object and VMA properties, arguments that control map flags (ro, kind, etc) are passed explicitly at map time. The compatibility hacks to implement the old frontend on top of the new driver backends have been replaced with something similar to implement the old frontend's interfaces on top of the new frontend.

2017-11-02drm/nouveau/mmu/gp100,gp10b: implement new vmm backendBen Skeggs
Adds support for: - 64KiB/2MiB big page sizes (128KiB not supported by HW with new PT layout). - System-memory PTs. - LPTE "invalid" state. - (Tegra) Use of video memory aperture. - Sparse PDEs/PTEs. - Additional blocklinear kinds. - 49-bit address-space. GP100 supports an entirely new 5-level page table layout that provides an expanded 49-bit address-space. It also supports the layout present on previous generations, which we've been making do with until now. This commit implements support for the new layout, and enables it by default.

2017-11-02drm/nouveau/mmu/gk104,gk20a: implement new vmm backendBen Skeggs
Adds support for: - 64KiB big page size. - System-memory PTs. - LPTE "invalid" state. - (Tegra) Use of video memory aperture. Adds support for marking LPTEs invalid, resulting in the corresponding SPTEs being ignored, which is supposed to speed up TLB invalidates. On The Tegra side, this will switch to using the video memory aperture for all mappings. The HW will still target non-coherent system memory, but this aperture needs to be selected in order to support compression. Tegra's instmem backend somewhat cheated to get this effect previously.
