gpu: nvgpu: enable HWPM Mode-E context switch
- This patch enables HWPM Mode-E context switch for gv11b.
- 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.
- For Mode-E ctxsw it is required that engine_sel
is set to 0xFFFFFFFF.
- Default 0 is a valid signal and causes problems.
