Subject: Re: [Patch v11 08/10] perf dwarf-regs: Add SIMD/eGPRs support for x86 DWARF registers
Date: Mon, 14 Sep 2026 01:56:17 +0000 [thread overview]
Message-ID: <20260914015617.F2E731F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260914014049.2061519-9-dapeng1.mi@linux.intel.com>
> Enhance the x86-specific DWARF register handling by adding support for
> SIMD and eGPRs registers.
>
> This update is based on the "DWARF Register Number Mapping" table from
> the "System V Application Binary Interface AMD64 Architecture Processor
> Supplement" (version 1.0).
>
> Modifications include:
> - Updating the x86_64_regidx_table[] array to incorporate SIMD and eGPRs
> registers.
> - Enhancing the __get_dwarf_regnum_for_perf_regnum_x86_64() function to
> retrieve the DWARF register index for eGPRs.
>
> Since currently libdw doesn't support SIMD and APX eGPRs registers yet,
> still keep the original return value for get_libdw_frame_nregs() helper.
>
> Signed-off-by: Dapeng Mi <dapeng1.mi@linux.intel.com>
