-+ select ZLIB_INFLATE
-+ help
-+ Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File
-+ System). Squashfs is a highly compressed read-only filesystem for Linux.
-+ It uses zlib compression to compress both files, inodes and directories.
-+ Inodes in the system are very small and all blocks are packed to minimise
-+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
-+ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full
-+ uid/gid information, hard links and timestamps.
-+
-+ Squashfs is intended for general read-only filesystem use, for archival
-+ use (i.e. in cases where a .tar.gz file may be used), and in embedded
-+ systems where low overhead is needed. Further information and filesystem tools
-+ are available from http://squashfs.sourceforge.net.
-+
-+ If you want to compile this as a module ( = code which can be
-+ inserted in and removed from the running kernel whenever you want),
-+ say M here and read <file:Documentation/modules.txt>. The module
-+ will be called squashfs. Note that the root file system (the one
-+ containing the directory /) cannot be compiled as a module.

-+ int "Number of fragments cached" if SQUASHFS_EMBEDDED

-+ help
-+ By default SquashFS caches the last 3 fragments read from
-+ the filesystem. Increasing this amount may mean SquashFS
-+ has to re-read fragments less often from disk, at the expense
-+ of extra system memory. Decreasing this amount will mean
-+ SquashFS uses less memory at the expense of extra reads from disk.
-+
-+ Note there must be at least one cached fragment. Anything
-+ much more than three will probably not make much difference.
-+
-+config SQUASHFS_VMALLOC
-+ bool "Use Vmalloc rather than Kmalloc" if SQUASHFS_EMBEDDED
-+ depends on SQUASHFS
-+ default n
-+ help
-+ By default SquashFS uses kmalloc to obtain fragment cache memory.
-+ Kmalloc memory is the standard kernel allocator, but it can fail
-+ on memory constrained systems. Because of the way Vmalloc works,
-+ Vmalloc can succeed when kmalloc fails. Specifying this option
-+ will make SquashFS always use Vmalloc to allocate the
-+ fragment cache memory.

-+ help
-+ Saying Y here includes support for SquashFS 3.2 (a Compressed Read-Only File
-+ System). Squashfs is a highly compressed read-only filesystem for Linux.
-+ It uses zlib compression to compress both files, inodes and directories.
-+ Inodes in the system are very small and all blocks are packed to minimise
-+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
-+ SquashFS 3.1 supports 64 bit filesystems and files (larger than 4GB), full
-+ uid/gid information, hard links and timestamps.
-+
-+ Squashfs is intended for general read-only filesystem use, for archival
-+ use (i.e. in cases where a .tar.gz file may be used), and in embedded
-+ systems where low overhead is needed. Further information and filesystem tools
-+ are available from http://squashfs.sourceforge.net.
-+
-+ If you want to compile this as a module ( = code which can be
-+ inserted in and removed from the running kernel whenever you want),
-+ say M here and read <file:Documentation/modules.txt>. The module
-+ will be called squashfs. Note that the root file system (the one
-+ containing the directory /) cannot be compiled as a module.

-+
-+config SQUASHFS_FRAGMENT_CACHE_SIZE
-+ int "Number of fragments cached" if SQUASHFS_EMBEDDED
-+ depends on SQUASHFS
-+ default "3"
-+ help
-+ By default SquashFS caches the last 3 fragments read from
-+ the filesystem. Increasing this amount may mean SquashFS
-+ has to re-read fragments less often from disk, at the expense
-+ of extra system memory. Decreasing this amount will mean
-+ SquashFS uses less memory at the expense of extra reads from disk.
-+
-+ Note there must be at least one cached fragment. Anything
-+ much more than three will probably not make much difference.
-+
-+config SQUASHFS_VMALLOC
-+ bool "Use Vmalloc rather than Kmalloc" if SQUASHFS_EMBEDDED
-+ depends on SQUASHFS
-+ default n
-+ help
-+ By default SquashFS uses kmalloc to obtain fragment cache memory.
-+ Kmalloc memory is the standard kernel allocator, but it can fail
-+ on memory constrained systems. Because of the way Vmalloc works,
-+ Vmalloc can succeed when kmalloc fails. Specifying this option
-+ will make SquashFS always use Vmalloc to allocate the
-+ fragment cache memory.

-+
-+uvesafb - A Generic Driver for VBE2+ compliant video cards
-+==========================================================
-+
-+1. Requirements
-+---------------
-+
-+uvesafb should work with any video card that has a Video BIOS compliant
-+with the VBE 2.0 standard.
-+
-+Unlike other drivers, uvesafb makes use of a userspace helper called
-+v86d. v86d is used to run the x86 Video BIOS code in a simulated and
-+controlled environment. This allows uvesafb to function on arches other
-+than x86. Check the v86d documentation for a list of currently supported
-+arches.
-+
-+v86d source code can be downloaded from the following website:
-+ http://dev.gentoo.org/~spock/projects/uvesafb
-+
-+Please refer to the v86d documentation for detailed configuration and
-+installation instructions.
-+
-+Note that the v86d userspace helper has to be available at all times in
-+order for uvesafb to work properly. If you want to use uvesafb during
-+early boot, you will have to include v86d into an initramfs image, and
-+either compile it into the kernel or use it as an initrd.
-+
-+2. Caveats and limitations
-+--------------------------
-+
-+uvesafb is a _generic_ driver which supports a wide variety of video
-+cards, but which is ultimately limited by the Video BIOS interface.
-+The most important limitations are:
-+
-+- Lack of any type of acceleration.
-+- A strict and limited set of supported video modes. Often the native
-+ or most optimal resolution/refresh rate for your setup will not work
-+ with uvesafb, simply because the Video BIOS doesn't support the
-+ video mode you want to use. This can be especially painful with
-+ widescreen panels, where native video modes don't have the 4:3 aspect
-+ ratio, which is what most BIOS-es are limited to.
-+- Adjusting the refresh rate is only possible with a VBE 3.0 compliant
-+ Video BIOS. Note that many nVidia Video BIOS-es claim to be VBE 3.0
-+ compliant, while they simply ignore any refresh rate settings.
-+
-+3. Configuration
-+----------------
-+
-+uvesafb can be compiled either as a module, or directly into the kernel.
-+In both cases it supports the same set of configuration options, which
-+are either given on the kernel command line or as module parameters, e.g.:
-+
-+ video=uvesafb:1024x768-32,mtrr:3,ywrap (compiled into the kernel)
-+
-+ # modprobe uvesafb mode=1024x768-32 mtrr=3 scroll=ywrap (module)
-+
-+Accepted options:
-+
-+ypan Enable display panning using the VESA protected mode
-+ interface. The visible screen is just a window of the
-+ video memory, console scrolling is done by changing the
-+ start of the window. Available on x86 only.
-+
-+ywrap Same as ypan, but assumes your gfx board can wrap-around
-+ the video memory (i.e. starts reading from top if it
-+ reaches the end of video memory). Faster than ypan.
-+ Available on x86 only.
-+
-+redraw Scroll by redrawing the affected part of the screen, this
-+ is the safe (and slow) default.
-+
-+(If you're using uvesafb as a module, the above three options are
-+ used a parameter of the scroll option, e.g. scroll=ypan.)
-+
-+vgapal Use the standard VGA registers for palette changes.
-+
-+pmipal Use the protected mode interface for palette changes.
-+ This is the default if the protected mode interface is
-+ available. Available on x86 only.
-+
-+mtrr:n Setup memory type range registers for the framebuffer
-+ where n:
-+ 0 - disabled (equivalent to nomtrr) (default)
-+ 1 - uncachable
-+ 2 - write-back
-+ 3 - write-combining
-+ 4 - write-through
-+
-+ If you see the following in dmesg, choose the type that matches
-+ the old one. In this example, use "mtrr:2".
-+...
-+mtrr: type mismatch for e0000000,8000000 old: write-back new: write-combining
-+...
-+
-+nomtrr Do not use memory type range registers.
-+
-+vremap:n
-+ Remap 'n' MiB of video RAM. If 0 or not specified, remap memory
-+ according to video mode.
-+
-+vtotal:n
-+ If the video BIOS of your card incorrectly determines the total
-+ amount of video RAM, use this option to override the BIOS (in MiB).
-+
-+<mode> The mode you want to set, in the standard modedb format. Refer to
-+ modedb.txt for a detailed description. When uvesafb is compiled as
-+ a module, the mode string should be provided as a value of the
-+ 'mode' option.
-+
-+vbemode:x
-+ Force the use of VBE mode x. The mode will only be set if it's
-+ found in the VBE-provided list of supported modes.
-+ NOTE: The mode number 'x' should be specified in VESA mode number
-+ notation, not the Linux kernel one (eg. 257 instead of 769).
-+ HINT: If you use this option because normal <mode> parameter does
-+ not work for you and you use a X server, you'll probably want to
-+ set the 'nocrtc' option to ensure that the video mode is properly
-+ restored after console <-> X switches.
-+
-+nocrtc Do not use CRTC timings while setting the video mode. This option
-+ has any effect only if the Video BIOS is VBE 3.0 compliant. Use it
-+ if you have problems with modes set the standard way. Note that
-+ using this option implies that any refresh rate adjustments will
-+ be ignored and the refresh rate will stay at your BIOS default (60 Hz).
-+
-+noedid Do not try to fetch and use EDID-provided modes.
-+
-+noblank Disable hardware blanking.
-+
-+v86d:path
-+ Set path to the v86d executable. This option is only available as
-+ a module parameter, and not as a part of the video= string. If you
-+ need to use it and have uvesafb built into the kernel, use
-+ uvesafb.v86d="path".
-+
-+Additionally, the following parameters may be provided. They all override the
-+EDID-provided values and BIOS defaults. Refer to your monitor's specs to get
-+the correct values for maxhf, maxvf and maxclk for your hardware.
-+
-+maxhf:n Maximum horizontal frequency (in kHz).
-+maxvf:n Maximum vertical frequency (in Hz).
-+maxclk:n Maximum pixel clock (in MHz).
-+
-+4. The sysfs interface
-+----------------------
-+
-+uvesafb provides several sysfs nodes for configurable parameters and
-+additional information.
-+
-+Driver attributes:
-+
-+/sys/bus/platform/drivers/uvesafb
-+ - v86d (default: /sbin/v86d)
-+ Path to the v86d executable. v86d is started by uvesafb
-+ if an instance of the daemon isn't already running.
-+
-+Device attributes:
-+
-+/sys/bus/platform/drivers/uvesafb/uvesafb.0
-+ - nocrtc
-+ Use the default refresh rate (60 Hz) if set to 1.
-+
-+ - oem_product_name
-+ - oem_product_rev
-+ - oem_string
-+ - oem_vendor
-+ Information about the card and its maker.
-+
-+ - vbe_modes
-+ A list of video modes supported by the Video BIOS along with their
-+ VBE mode numbers in hex.
-+
-+ - vbe_version
-+ A BCD value indicating the implemented VBE standard.
-+
-+5. Miscellaneous
-+----------------
-+
-+Uvesafb will set a video mode with the default refresh rate and timings
-+from the Video BIOS if you set pixclock to 0 in fb_var_screeninfo.
