* gpu: nvgpu: vgpu: profiler reservation supportPeter Daifuku2017-03-24
| | | | | | | | | | | | | | | | | | | | | | | Support for hwpm reservations in the virtual case: - Add session ops for checking and setting global and context reservations, and releasing reservations - in the native case, these just update reservation counts and flags - in the vgpu case, when the reservation count is 0, check with the RM server that a reservation is possible: for global reservations, no other guest can have a reservation; for context reservations, no other guest can have a global reservation - in the vgpu case, when the reservation count is decremented to 0, notify the RM server that the guest no longer has any reservations Bug 1775465 JIRA VFND-3428 Change-Id: Idf115b730e465e35d0745c96a8f8ab6b645c7cae Signed-off-by: Peter Daifuku <pdaifuku@nvidia.com> Reviewed-on: http://git-master/r/1323375 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | Move all programming of FB to fb_*.c files, and remove the inclusion of FB hardware headers from other files. TLB invalidate function took previously a pointer to VM, but the new API takes only a PDB mem_desc, because FB does not need to know about higher level VM. GPC MMU is programmed from the same function as FB MMU, so added dependency to GR hardware header to FB. GP106 ACR was also triggering a VPR fetch, but that's not applicable to dGPU, so removed that call.

At the same time we can replace calls to clk framework with the new HAL and drop direct dependency to clk framework. gp10b ops were replaced as a whole at HAL initialization. That replaces anything set in platform probe stage, so reduce that to touch only clock gating regs.
