drm/hisilicon: Add depends on MMU

2022-09-20T09:15:09Z

The Kconfig symbol depended on MMU but was dropped by the commit acad3fe650a5 ("drm/hisilicon: Removed the dependency on the mmu") because it already had as a dependency ARM64 that already selects MMU. But later, commit a0f25a6bb319 ("drm/hisilicon/hibmc: Allow to be built if COMPILE_TEST is enabled") allowed the driver to be built for non-ARM64 when COMPILE_TEST is set but that could lead to unmet direct dependencies and linking errors. Prevent a kconfig warning when MMU is not enabled by making DRM_HISI_HIBMC depend on MMU.

drm/hisilicon/hibmc: Allow to be built if COMPILE_TEST is enabled

2022-01-27T12:38:04Z

The commit feeb07d0ca5a ("drm/hisilicon/hibmc: Make CONFIG_DRM_HISI_HIBMC depend on ARM64") made the driver Kconfig symbol to depend on ARM64 since it only supports that architecture and loading the module on others would lead to incorrect video modes being used. But it also prevented the driver to be built on other architectures which is useful to have compile test coverage when doing subsystem wide changes. Make the dependency instead to be (ARM64 || COMPILE_TEST), so the driver is buildable when the CONFIG_COMPILE_TEST option is enabled.

drm/hisilicon/hibmc: Replace module initialization with DRM helpers

2022-01-19T17:40:13Z

Replace module_pci_driver() with drm_module_pci_driver(). The DRM macro respects drm_firmware_drivers_only() and fails if the flag has been set.

drm/hisilicon/hibmc: Convert to Linux IRQ interfaces

2021-07-08T12:12:43Z

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers don't benefit from using it.

drm/aperture: Pass DRM driver structure instead of driver name

2021-07-01T09:11:55Z

Print the name of the DRM driver when taking over fbdev devices. Makes the output to dmesg more consistent. Note that the driver name is only used for printing a string to the kernel log. No UAPI is affected by this change.
