Legacy profiler does not reserve PMA stream resource with PM reservation system. Also, HWPM system reset is separately implemented in membuf disable path. And it does not even restore perf unit SLCG prod values. Allcoate a dummy profiler object for debug session in perfbuf map path. Free it in perfbuf unmap path. This has advantage of synchronizing PMA stream reservation with new profiler stack. And this also leverages HWPM system reset and SLCG handling code during resource reservation. Remove explicit HWPM reset from gops.perf.membuf_reset_streaming() HALs Bug 2510974 Jira NVGPU-5360 Change-Id: I54c5202b6251dea3d80a4dfc011e8a296339e07f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvgpu/+/2399595 Reviewed-by: automaticguardword <automaticguardword@nvidia.com> Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> Reviewed-by: svc-mobile-misra <svc-mobile-misra@nvidia.com> Reviewed-by: svc-mobile-cert <svc-mobile-cert@nvidia.com> Reviewed-by: Alex Waterman <alexw@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
