drm/gpuvm: allow building as module

2023-09-25T23:58:28Z

Currently, the DRM GPUVM does not have any core dependencies preventing a module build. Also, new features from subsequent patches require helpers (namely drm_exec) which can be built as module.

drm: fix up fbdev Kconfig defaults

2023-09-18T08:52:55Z

As a result of the recent Kconfig reworks, the default settings for the framebuffer interfaces changed in unexpected ways: Configurations that leave CONFIG_FB disabled but use DRM now get DRM_FBDEV_EMULATION by default. This also turns on the deprecated /dev/fb device nodes for machines that don't actually want it. In turn, configurations that previously had DRM_FBDEV_EMULATION enabled now only get the /dev/fb front-end but not the more useful framebuffer console, which is not selected any more. We had previously decided that any combination of the three frontends (FB_DEVICE, FRAMEBUFFER_CONSOLE and LOGO) should be selectable, but the new default settings mean that a lot of defconfig files would have to get adapted. Change the defaults back to what they were in Linux 6.5: - Leave DRM_FBDEV_EMULATION turned off unless CONFIG_FB is enabled. Previously this was a hard dependency but now the two are independent. However, configurations that enable CONFIG_FB probably also want to keep the emulation for DRM, while those without FB presumably did that intentionally in the past. - Leave FB_DEVICE turned off for FB=n. Following the same logic, the deprecated option should not automatically get enabled here, most users that had FB turned off in the past do not want it, even if they want the console - Turn the FRAMEBUFFER_CONSOLE option on if DRM_FBDEV_EMULATION is set to avoid having to change defconfig files that relied on it being selected unconditionally in the past. This also makes sense since both LOGO and FB_DEVICE are now disabled by default for builds without CONFIG_FB, but DRM_FBDEV_EMULATION would make no sense if all three are disabled.

drm: Drop select FRAMEBUFFER_CONSOLE for DRM_FBDEV_EMULATION

2023-08-04T16:49:15Z

The commit c242f48433e7 ("drm: Make FB_CORE to be selected if DRM fbdev emulation is enabled") changed DRM_FBDEV_EMULATION from 'depends on FB' to an effective 'select FB_CORE', so any config that previously had DRM=y and FB=n now has FB_CORE=y and FRAMEBUFFER_CONSOLE=y. This leads to unmet direct dependencies detected for FRAMEBUFFER_CONSOLE as reported by Arthur Grillo, e.g: WARNING: unmet direct dependencies detected for FRAMEBUFFER_CONSOLE Depends on [n]: VT [=n] && FB_CORE [=y] && !UML [=y] Selected by [y]: - DRM_FBDEV_EMULATION [=y] && HAS_IOMEM [=y] && DRM [=y] && !EXPERT [=n] Arnd Bergmann suggests to drop the select FRAMEBUFFER_CONSOLE for the DRM_FBDEV_EMULATION Kconfig symbol, since a possible use case could be to enable DRM fbdev emulation but without a framebuffer console.
