* gpu: nvgpu: avoid faulty elpg protectionKonsta Hölttä2021-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | Don't store the return value of elpg re-enable if disable fails; this could make the local status value zero again, causing the elpg-protected call to be executed with elpg still enabled and elpg re-enabled twice. Commit c90585856567 ("gpu: nvgpu: add cg and pg function") introduced this bug; failure of re-enabling after a failed disable might be another problem (and it's not clear why this is done in the first place) which isn't propagated to the caller, but that would belong to another patch.

* gpu: nvgpu: Add configurable comptag_mem_deduct sysfs node per deviceNicolin Chen2018-09-04
| | | | | | | | | | | | | | | | | | | | | | | Adding a comptag_mem_deduct in the platform_gk20a has certain problems: 1) It's not really convenient for platform users to configure it. 2) All products using the same GPU have to share the same configuration. So this patch moves this comptag_mem_deduct from struct platform_gk20a to struct gr_gk20a (per device). And it adds an sysfs node for products or platform users to easily configure from user space. Note: The comptag memory will not be allocated until the GPU driver goes through the final poweron routine. So the user space has a small window to configure this sysfs node.

These sizes are different for gv11b from gp10b. For gp10b used smaller buffer sizes than specified value in hw manuals as per sw requirement. Also used gv11b specific preemption related functions: gr_gv11b_set_ctxsw_preemption_mode gr_gv11b_update_ctxsw_preemption_mode This is required because preemption related buffer sizes are different for gv11b from gp10b. More optimization will be done as part of NVGPU-484. Another issue fixed is: gpu va for preemption buffers still needs to be 8 bit aligned, even though 49 bits available now. This done because of legacy implementation of fecs ucode.
