[PATCH] vmwgfx: allow building with CONFIG_HAS_IOPORT disabled
From: Arnd Bergmann
Date: Fri Oct 04 2024 - 16:51:09 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
The older version of the vmwgfx driver requires port I/O in order to work:
In file included from arch/arm64/include/asm/io.h:298,
from drivers/gpu/drm/vmwgfx/vmwgfx_kms.c:28:
drivers/gpu/drm/vmwgfx/vmwgfx_drv.h: In function 'vmw_read':
include/asm-generic/io.h:626:15: error: call to '_outl' declared with attribute error: outl() requires CONFIG_HAS_IOPORT
626 | #define _outl _outl
include/asm-generic/io.h:663:14: note: in expansion of macro '_outl'
663 | #define outl _outl
| ^~~~~
drivers/gpu/drm/vmwgfx/vmwgfx_drv.h:692:17: note: in expansion of macro 'outl'
692 | outl(offset, dev_priv->io_start + SVGA_INDEX_PORT);
| ^~~~
Change the version check to hardcode the v3 version and remove the PCI
ID for v2 in configurations that only support v3.
