Subject: [PATCH] drm: ttm: select CONFIG_SHMEM
Date: Fri, 11 Apr 2025 14:55:25 +0200 [thread overview]
Message-ID: <20250411125532.1444682-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
ttm now directly calls into shmem code, which fails to build when
that is disabled at compile time.
ld.lld-21: error: undefined symbol: shmem_writeout
>>> referenced by ttm_backup.c
>>> drivers/gpu/drm/ttm/ttm_backup.o:(ttm_backup_backup_page) in archive vmlinux.a
Select SHMEM here.
Fixes: fe75adffac33 ("ttm: Call shmem_writeout() from ttm_backup_backup_page()")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
