Subject: [PATCH] gpu: host1x: select CONFIG_DMA_SHARED_BUFFER
Date: Mon, 27 Sep 2021 11:36:59 +0200 [thread overview]
Message-ID: <20210927093705.458573-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Linking fails when dma-buf is disabled:
ld.lld: error: undefined symbol: dma_fence_release
>>> referenced by fence.c
>>> gpu/host1x/fence.o:(host1x_syncpt_fence_enable_signaling) in archive drivers/built-in.a
>>> referenced by fence.c
>>> gpu/host1x/fence.o:(host1x_fence_signal) in archive drivers/built-in.a
>>> referenced by fence.c
>>> gpu/host1x/fence.o:(do_fence_timeout) in archive drivers/built-in.a
Fixes: 687db2207b1b ("gpu: host1x: Add DMA fence implementation")
