Subject: [PATCH RESEND] drm/aspeed: fix Kconfig warning & subsequent build errors
Date: Sun, 11 Oct 2020 16:01:31 -0700 [thread overview]
Message-ID: <20201011230131.4922-1-rdunlap@infradead.org> (raw)
kernel test robot reported build errors (undefined references)
that didn't make much sense. After reproducing them, there is also
a Kconfig warning that is the root cause of the build errors, so
fix that Kconfig problem.
Fixes this Kconfig warning:
WARNING: unmet direct dependencies detected for CMA
Depends on [n]: MMU [=n]
Selected by [m]:
- DRM_ASPEED_GFX [=m] && HAS_IOMEM [=y] && DRM [=m] && OF [=y] && (COMPILE_TEST [=y] || ARCH_ASPEED) && HAVE_DMA_CONTIGUOUS [=y]
and these dependent build errors:
(.text+0x10c8c): undefined reference to `start_isolate_page_range'
microblaze-linux-ld: (.text+0x10f14): undefined reference to `test_pages_isolated'
microblaze-linux-ld: (.text+0x10fd0): undefined reference to `undo_isolate_page_range'
Fixes: 76356a966e33 ("drm: aspeed: Clean up Kconfig options")
