Subject: [PATCH 0/4] perf: support zstd-compressed kernel modules
Date: Wed, 14 Oct 2026 20:34:06 +0300 [thread overview]
Message-ID: <20261014-perf-zstd-v1-0-9652727886fa@intelfx.name> (raw)
This extends in-perf zstd code to add an interface for streaming
decompression of an entire file, and uses that interface in dso.c to
support handling of zstd-compressed DSOs (e.g., zstd-compressed kernel
modules, as shipped by various distros including Arch).

Ivan Shapovalov (4):
perf: zstd: zstd_decompress_stream -> zstd_decompress_buffer
perf: zstd: factor out zstd_init_{c,d}stream()
perf: zstd: add streaming decompression and format probe functions
perf: support zstd-compressed kernel modules
