503d489dba gpu: nvgpu: Initialize hwpm perfmons (engine_sel)
- For Mode-E ctxsw it is required that engine_sel
is set to 0xFFFFFFFF.
- Default 0 is a valid signal and causes problems.

e14fdcd8f1 gpu: nvgpu: enable HWPM Mode-E context switch
- Write new pm mode to context buffer header. Ucode use
this mode to enable mode-e context switch. This is Mode-B
context switch of PMs with Mode-E streamout on one context.
If this mode is set, Ucode makes sure that Mode-E pipe
(perfmons, routers, pma) is idle before it context switches PMs.
- This allows us to collect counters in a secure way
(i.e. on context basis) with stream out.

10c3d4447d gpu: nvgpu: gv11b: enable RMW for gpu atomics
Separate HAL added in gv11b and gv100 for
init_gpc_mmu function.
In gv11b HAL, RMW is enabled for gpu atomics
as default.
In gv100 HAL, GPC atomic capability mode will
get set based on the FB MMU capability.
If GPU is connected through NVLINK then mmu
will be set to RMW mode, else it will be in
L2 mode.

a0dfb2b911 gpu: nvgpu: gv100: consider floorswept FBPA for getting unicast list
In gr_gv11b/gk20a_create_priv_addr_table() we do not consider floorswept FBPAs
and just calculate the unicast list assuming all FBPAs are present
This generates incorrect list of unicast addresses

Fix this introducing new HAL ops.gr.split_fbpa_broadcast_addr
Set gr_gv100_get_active_fpba_mask() for GV100
Set gr_gk20a_split_fbpa_broadcast_addr() for rest of the chips

gr_gv100_get_active_fpba_mask() will first get active FPBA mask and generate
unicast list only for active FBPAs

77b806fe7e gpu: nvgpu: gv100: fix PMA list alignment in ctxsw buffer
GV100 ucode is changed so that it expects LIST_nv_perf_pma_ctx_reg list in
ctxsw buffer to be 256 byte aligned but same change is not applied to other
chip ucodes

ADD new HAL (*add_ctxsw_reg_perf_pma) to configure PMA register list and
define a common HAL gr_gk20a_add_ctxsw_reg_perf_pma() for all other
chips except GV100

Define a separate HAL for GV100 gr_gv100_add_ctxsw_reg_perf_pma() and fix
the required alignment in this function

66751bc05d gpu: nvgpu: gv100: fix num_fbpas while adding ctxsw buffer entries
For LIST_nv_pm_fbpa_ctx_regs, we right now call
add_ctxsw_buffer_map_entries_subunits() to add registers corresponding
to all the FBPAs

But while configuring total number of registers, we do not consider
floorswept FBPAs and that causes misalignment in subsequent lists for GV100

Fix this by reading disabled/floorswept FBPAs from fuse and consider only those
FBPAs which are active for GV100

Add new HAL (*add_ctxsw_reg_pm_fbpa) to support this setting and define a
common HAL gr_gk20a_add_ctxsw_reg_pm_fbpa() for all chips except GV100

Define GV100 specific gr_gv100_add_ctxsw_reg_pm_fbpa() with above mentioned
implementation to consider floorsweeping

On gv11b we can have multiple SMs per TPC. Add sm_per_tpc in
vgpu constants to properly dimension the virtual SM to TPC/GPC
mapping in virtualization case.
Use TEGRA_VGPU_CMD_GET_SMS_MAPPING to query current mapping.

ed8ac6e005 gpu: nvgpu: fix smid generation of perf tables
SMID tables were generated according with the local tpc and the pagepool and cb
buffers from a different chip and did not take performance in consideration,
which made compute kernels hang with CTAs on the fly.

This change ensures we are using the right sizes and adds proper enumeration
of smids.
