That's OK with me, but I'm also OK taking them through the RISC-V tree. Note that cpuinfo dependency seems to be triggering kasan failures, so we'll at least need to sort that out.

As i remember correctly you were willing to take these patches into 6.0 =). Well they are acked by Palmer and [2] series, which my series depends on, also have been accepted. I can resend if it helps you. Yours, Nikita Shubin.

I picked it from this Message-ID with b4, applied cleanly, but yesterday the merge window closed for v6.1, I applied it to my perf/core branch, for v6.2. Thanks, - Arnaldo
From: Nikita Shubin <n.shubin@yadro.com> This series aims to provide matching vendor SoC with corresponded JSON bindings. The ID string is proposed to be in form of MVENDORID-MARCHID-MIMPID, for example for Sifive Unmatched the corresponding string will be: 0x489-0x8000000000000007-0x[[:xdigit:]]+,v1,sifive/u74,core Where MIMPID can vary as all impl supported the same number of events, this might not be true for all future SoC however. Also added SBI firmware events pretty names, as any firmware that supports SBI PMU should also support firmare events [1]. Series depends on patch by Anup Patel, exposing mvendor, marchid and mimpid to "/proc/cpuinfo" [2].
