Subject: [PATCH] perf arch events: Fix duplicate RISC-V SBI firmware event name
Date: Thu, 18 Jul 2024 23:22:54 +0800 [thread overview]
Message-ID: <20240718152254.16007-1-eric.lin@sifive.com> (raw)
Currently, the RISC-V firmware JSON file has duplicate event name
"FW_SFENCE_VMA_RECEIVED". According to the RISC-V SBI PMU extension[1],
the event name should be "FW_SFENCE_VMA_ASID_SENT".
Before this patch:
$ perf list
firmware:
fw_access_load
[Load access trap event. Unit: cpu]
fw_access_store
[Store access trap event. Unit: cpu]
....
fw_set_timer
[Set timer event. Unit: cpu]
fw_sfence_vma_asid_received
[Received SFENCE.VMA with ASID request from other HART event. Unit: cpu]
fw_sfence_vma_received
[Sent SFENCE.VMA with ASID request to other HART event. Unit: cpu]
After this patch:
$ perf list
firmware:
fw_access_load
[Load access trap event. Unit: cpu]
fw_access_store
[Store access trap event. Unit: cpu]
.....
fw_set_timer
[Set timer event. Unit: cpu]
fw_sfence_vma_asid_received
[Received SFENCE.VMA with ASID request from other HART event. Unit: cpu]
fw_sfence_vma_asid_sent
[Sent SFENCE.VMA with ASID request to other HART event. Unit: cpu]
fw_sfence_vma_received
[Received SFENCE.VMA request from other HART event. Unit: cpu]
