fbdev/chipsfb: Use fbdev I/O helpers

2023-08-04T13:54:35+00:00

Set struct fb_ops and with FB_DEFAULT_IOMEM_OPS, fbdev's initializer
for I/O memory. Sets the callbacks to the cfb_ and fb_io_ functions.
Select the correct modules with Kconfig's FB_IOMEM_HELPERS token.

The macro and token set the currently selected values, so there is
no functional change.

v3:
	* use _IOMEM_ in commit message
v2:
	* updated to use _IOMEM_ tokens

fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs

2023-07-24T14:50:38+00:00

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags
has been allocated to zero by framebuffer_alloc(). So do not set it.

Flags should signal differences from the default values. After cleaning
up all occurrences of FBINFO_DEFAULT, the token will be removed.

v4:
	* clarify commit message (Geert, Dan)
v2:
	* fix commit message (Miguel)

fbdev: Rename fb_mem*() helpers

2023-05-18T09:07:54+00:00

Update the names of the fb_mem*() helpers to be consistent with their
regular counterparts. Hence, fb_memset() now becomes fb_memset_io(),
fb_memcpy_fromfb() now becomes fb_memcpy_fromio() and fb_memcpy_tofb()
becomes fb_memcpy_toio(). No functional changes.

v6:
	* update new file fb_io_fops.c

fbdev: Add support for the nomodeset kernel parameter

2022-11-16T12:26:25+00:00

Support the kernel's nomodeset parameter for all PCI-based fbdev
drivers that use aperture helpers to remove other, hardware-agnostic
graphics drivers.

The parameter is a simple way of using the firmware-provided scanout
buffer if the hardware's native driver is broken. The same effect
could be achieved with per-driver options, but the importance of the
graphics output for many users makes a single, unified approach
worthwhile.

With nomodeset specified, the fbdev driver module will not load. This
unifies behavior with similar DRM drivers. In DRM helpers, modules
first check the nomodeset parameter before registering the PCI
driver. As fbdev has no such module helpers, we have to modify each
driver individually.

The name 'nomodeset' is slightly misleading, but has been chosen for
historical reasons. Several drivers implemented it before it became a
general option for DRM. So keeping the existing name was preferred over
introducing a new one.

v2:
	* print a warning if a driver does not init (Helge)
	* wrap video_firmware_drivers_only() in helper

fbdev: Remove conflicting devices on PCI bus

2022-07-19T11:19:11+00:00

Remove firmware devices on the PCI bus, by calling
aperture_remove_conflicting_pci_devices() in the probe function of
each related fbdev driver. iSo far, most of these drivers did not
remove conflicting VESA or EFI devices, or outride failed for
resource conflicts (i.e., matroxfb.) This must have been broken
for quite some time.
