Subject: [PATCH] drm/panic: Select ZLIB_DEFLATE for DRM_PANIC_SCREEN_QR_CODE
Date: Fri, 4 Oct 2024 01:07:34 +0200 [thread overview]
Message-ID: <20241003230734.653717-1-ojeda@kernel.org> (raw)
Under `CONFIG_DRM_PANIC_SCREEN_QR_CODE=y`, zlib is used:
ld.lld: error: undefined symbol: zlib_deflate_workspacesize
>>> referenced by drm_panic.c
>>> drivers/gpu/drm/drm_panic.o:(drm_panic_qr_init) in archive vmlinux.a
Thus select `CONFIG_ZLIB_DEFLATE`.
Fixes: cb5164ac43d0 ("drm/panic: Add a QR code panic screen")

This option adds a QR code generator, and a panic screen with a QR
code. The QR code will contain the last lines of kmsg and other debug
