Merge tag 'fbdev-for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev
Pull fbdev updates from Helge Deller: "Three fbdev drivers (~8500 lines of code) removed. The Carillo Ranch fbdev driver is for an Intel product which was never shipped, and for the intelfb and the amba-clcd drivers the drm drivers can be used instead. The other code changes are minor: some fb_deferred_io flushing fixes, imxfb margin fixes and stifb cleanups. Summary: - Remove intelfb fbdev driver (Thomas Zimmermann) - Remove amba-clcd fbdev driver (Linus Walleij) - Remove vmlfb Carillo Ranch fbdev driver (Matthew Wilcox) - fb_deferred_io flushing fixes (Nam Cao) - imxfb code fixes and cleanups (Dario Binacchi) - stifb primary screen detection cleanups (Thomas Zimmermann)" * tag 'fbdev-for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev: (28 commits) fbdev/intelfb: Remove driver fbdev/hyperv_fb: Do not clear global screen_info firmware/sysfb: Clear screen_info state after consuming it fbdev/hyperv_fb: Remove firmware framebuffers with aperture helpers drm/hyperv: Remove firmware framebuffers with aperture helper fbdev/sis: Remove dependency on screen_info video/logo: use %u format specifier for unsigned int values video/sticore: Remove info field from STI struct arch/parisc: Detect primary video device from device instance fbdev/stifb: Allocate fb_info instance with framebuffer_alloc() video/sticore: Store ROM device in STI struct fbdev: flush deferred IO before closing fbdev: flush deferred work in fb_deferred_io_fsync() fbdev: amba-clcd: Delete the old CLCD driver fbdev: Remove support for Carillo Ranch driver fbdev: hgafb: fix kernel-doc comments fbdev: mmp: Fix typo and wording in code comment fbdev: fsl-diu-fb: Fix sparse warning due to virt_to_phys() prototype change fbdev: imxfb: add '*/' on a separate line in block comment fbdev: imxfb: use __func__ for function name ...

-=============================================================
-Intel 830M/845G/852GM/855GM/865G/915G/945G Framebuffer driver
-=============================================================
-
-A. Introduction
-===============
-
-This is a framebuffer driver for various Intel 8xx/9xx compatible
-graphics devices. These would include:
-
- - Intel 830M
- - Intel 845G
- - Intel 852GM
- - Intel 855GM
- - Intel 865G
- - Intel 915G
- - Intel 915GM
- - Intel 945G
- - Intel 945GM
- - Intel 945GME
- - Intel 965G
- - Intel 965GM
-
-B. List of available options
-=============================
-
- a. "video=intelfb"
- enables the intelfb driver
-
- Recommendation: required
-
- b. "mode=<xres>x<yres>[-<bpp>][@<refresh>]"
- select mode
-
- Recommendation: user preference
- (default = 1024x768-32@70)
-
- c. "vram=<value>"
- select amount of system RAM in MB to allocate for the video memory
- if not enough RAM was already allocated by the BIOS.
-
- Recommendation: 1 - 4 MB.
- (default = 4 MB)
-
- d. "voffset=<value>"
- select at what offset in MB of the logical memory to allocate the
- framebuffer memory. The intent is to avoid the memory blocks
- used by standard graphics applications (XFree86). Depending on your
- usage, adjust the value up or down, (0 for maximum usage, 63/127 MB
- for the least amount). Note, an arbitrary setting may conflict
- with XFree86.
-
- Recommendation: do not set
- (default = 48 MB)
-
- e. "accel"
- enable text acceleration. This can be enabled/reenabled anytime
- by using 'fbset -accel true/false'.
-
- Recommendation: enable
- (default = set)
-
- f. "hwcursor"
- enable cursor acceleration.
-
- Recommendation: enable
- (default = set)
-
- g. "mtrr"
- enable MTRR. This allows data transfers to the framebuffer memory
- to occur in bursts which can significantly increase performance.
- Not very helpful with the intel chips because of 'shared memory'.
-
- Recommendation: set
- (default = set)
-
- h. "fixed"
- disable mode switching.
-
- Recommendation: do not set
- (default = not set)
-
- The binary parameters can be unset with a "no" prefix, example "noaccel".
- The default parameter (not named) is the mode.
-
-C. Kernel booting
-=================
-
-Separate each option/option-pair by commas (,) and the option from its value
-with an equals sign (=) as in the following::
-
- video=intelfb:option1,option2=value2
-
-Sample Usage
-------------
-
-In /etc/lilo.conf, add the line::
-
- append="video=intelfb:mode=800x600-32@75,accel,hwcursor,vram=8"
-
-This will initialize the framebuffer to 800x600 at 32bpp and 75Hz. The
-framebuffer will use 8 MB of System RAM. hw acceleration of text and cursor
-will be enabled.
-
-Remarks
--------
-
-If setting this parameter doesn't work (you stay in a 80x25 text-mode),
-you might need to set the "vga=<mode>" parameter too - see vesafb.txt
-in this directory.
-
-
-D. Module options
-==================
-
-The module parameters are essentially similar to the kernel
-parameters. The main difference is that you need to include a Boolean value
-(1 for TRUE, and 0 for FALSE) for those options which don't need a value.
-
-Example, to enable MTRR, include "mtrr=1".
-
-Sample Usage
-------------
-
-Using the same setup as described above, load the module like this::
-
- modprobe intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
-
-Or just add the following to a configuration file in /etc/modprobe.d/::
-
- options intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
-
-and just do a::
-
- modprobe intelfb
-
-
-E. Acknowledgment:
-===================
-
- 1. Geert Uytterhoeven - his excellent howto and the virtual
- framebuffer driver code made this possible.
-
- 2. Jeff Hartmann for his agpgart code.
-
- 3. David Dawes for his original kernel 2.4 code.
-
- 4. The X developers. Insights were provided just by reading the
- XFree86 source code.
-
- 5. Antonino A. Daplas for his inspiring i810fb driver.
-
- 6. Andrew Morton for his kernel patches maintenance.
