25 | + Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File | ||
26 | + System). Squashfs is a highly compressed read-only filesystem for Linux. | ||
27 | + It uses zlib compression to compress both files, inodes and directories. | ||
28 | + Inodes in the system are very small and all blocks are packed to minimise | ||
29 | + data overhead. Block sizes greater than 4K are supported up to a maximum of 64K. | ||
30 | + SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full | ||
31 | + uid/gid information, hard links and timestamps. | ||
32 | + | ||
33 | + Squashfs is intended for general read-only filesystem use, for archival | ||
34 | + use (i.e. in cases where a .tar.gz file may be used), and in embedded | ||
35 | + systems where low overhead is needed. Further information and filesystem tools | ||
36 | + are available from http://squashfs.sourceforge.net. | ||
37 | + | ||
38 | + If you want to compile this as a module ( = code which can be | ||
39 | + inserted in and removed from the running kernel whenever you want), | ||
40 | + say M here and read <file:Documentation/modules.txt>. The module | ||
41 | + will be called squashfs. Note that the root file system (the one | ||
42 | + containing the directory /) cannot be compiled as a module. | ||

62 | + help | ||
63 | + By default SquashFS caches the last 3 fragments read from | ||
64 | + the filesystem. Increasing this amount may mean SquashFS | ||
65 | + has to re-read fragments less often from disk, at the expense | ||
66 | + of extra system memory. Decreasing this amount will mean | ||
67 | + SquashFS uses less memory at the expense of extra reads from disk. | ||

77 | + By default SquashFS uses kmalloc to obtain fragment cache memory. | ||
78 | + Kmalloc memory is the standard kernel allocator, but it can fail | ||
79 | + on memory constrained systems. Because of the way Vmalloc works, | ||
80 | + Vmalloc can succeed when kmalloc fails. Specifying this option | ||
81 | + will make SquashFS always use Vmalloc to allocate the | ||
82 | + fragment cache memory. | ||

18 | +uvesafb - A Generic Driver for VBE2+ compliant video cards | ||
19 | +========================================================== | ||
20 | + | ||
21 | +1. Requirements | ||
22 | +--------------- | ||
23 | + | ||
24 | +uvesafb should work with any video card that has a Video BIOS compliant | ||
25 | +with the VBE 2.0 standard. | ||
26 | + | ||
27 | +Unlike other drivers, uvesafb makes use of a userspace helper called | ||
28 | +v86d. v86d is used to run the x86 Video BIOS code in a simulated and | ||
29 | +controlled environment. This allows uvesafb to function on arches other | ||
30 | +than x86. Check the v86d documentation for a list of currently supported | ||
31 | +arches. | ||
32 | + | ||
33 | +v86d source code can be downloaded from the following website: | ||
34 | + http://dev.gentoo.org/~spock/projects/uvesafb | ||
35 | + | ||
36 | +Please refer to the v86d documentation for detailed configuration and | ||
37 | +installation instructions. | ||
38 | + | ||
39 | +Note that the v86d userspace helper has to be available at all times in | ||
40 | +order for uvesafb to work properly. If you want to use uvesafb during | ||
41 | +early boot, you will have to include v86d into an initramfs image, and | ||
42 | +either compile it into the kernel or use it as an initrd. | ||
43 | + | ||
44 | +2. Caveats and limitations | ||
45 | +-------------------------- | ||
46 | + | ||
47 | +uvesafb is a _generic_ driver which supports a wide variety of video | ||
48 | +cards, but which is ultimately limited by the Video BIOS interface. | ||
49 | +The most important limitations are: | ||
50 | + | ||
51 | +- Lack of any type of acceleration. | ||
52 | +- A strict and limited set of supported video modes. Often the native | ||
53 | + or most optimal resolution/refresh rate for your setup will not work | ||
54 | + with uvesafb, simply because the Video BIOS doesn't support the | ||
55 | + video mode you want to use. This can be especially painful with | ||
56 | + widescreen panels, where native video modes don't have the 4:3 aspect | ||
57 | + ratio, which is what most BIOS-es are limited to. | ||
58 | +- Adjusting the refresh rate is only possible with a VBE 3.0 compliant | ||
59 | + Video BIOS. Note that many nVidia Video BIOS-es claim to be VBE 3.0 | ||
60 | + compliant, while they simply ignore any refresh rate settings. | ||
61 | + | ||
62 | +3. Configuration | ||
63 | +---------------- | ||
64 | + | ||
65 | +uvesafb can be compiled either as a module, or directly into the kernel. | ||
66 | +In both cases it supports the same set of configuration options, which | ||
67 | +are either given on the kernel command line or as module parameters, e.g.: | ||
68 | + | ||
69 | + video=uvesafb:1024x768-32,mtrr:3,ywrap (compiled into the kernel) | ||
70 | + | ||
71 | + # modprobe uvesafb mode=1024x768-32 mtrr=3 scroll=ywrap (module) | ||
72 | + | ||
73 | +Accepted options: | ||
74 | + | ||
75 | +ypan Enable display panning using the VESA protected mode | ||
76 | + interface. The visible screen is just a window of the | ||
77 | + video memory, console scrolling is done by changing the | ||
78 | + start of the window. Available on x86 only. | ||
79 | + | ||
80 | +ywrap Same as ypan, but assumes your gfx board can wrap-around | ||
81 | + the video memory (i.e. starts reading from top if it | ||
82 | + reaches the end of video memory). Faster than ypan. | ||
83 | + Available on x86 only. | ||
84 | + | ||
85 | +redraw Scroll by redrawing the affected part of the screen, this | ||
86 | + is the safe (and slow) default. | ||
87 | + | ||
88 | +(If you're using uvesafb as a module, the above three options are | ||
89 | + used a parameter of the scroll option, e.g. scroll=ypan.) | ||
90 | + | ||
91 | +vgapal Use the standard VGA registers for palette changes. | ||
92 | + | ||
93 | +pmipal Use the protected mode interface for palette changes. | ||
94 | + This is the default if the protected mode interface is | ||
95 | + available. Available on x86 only. | ||
96 | + | ||
97 | +mtrr:n Setup memory type range registers for the framebuffer | ||
98 | + where n: | ||
99 | + 0 - disabled (equivalent to nomtrr) (default) | ||
100 | + 1 - uncachable | ||
101 | + 2 - write-back | ||
102 | + 3 - write-combining | ||
103 | + 4 - write-through | ||
104 | + | ||
105 | + If you see the following in dmesg, choose the type that matches | ||
106 | + the old one. In this example, use "mtrr:2". | ||
107 | +... | ||
108 | +mtrr: type mismatch for e0000000,8000000 old: write-back new: write-combining | ||
109 | +... | ||
110 | + | ||
111 | +nomtrr Do not use memory type range registers. | ||
112 | + | ||
113 | +vremap:n | ||
114 | + Remap 'n' MiB of video RAM. If 0 or not specified, remap memory | ||
115 | + according to video mode. | ||
116 | + | ||
117 | +vtotal:n | ||
118 | + If the video BIOS of your card incorrectly determines the total | ||
119 | + amount of video RAM, use this option to override the BIOS (in MiB). | ||
120 | + | ||
121 | +<mode> The mode you want to set, in the standard modedb format. Refer to | ||
122 | + modedb.txt for a detailed description. When uvesafb is compiled as | ||
123 | + a module, the mode string should be provided as a value of the | ||
124 | + 'mode' option. | ||
125 | + | ||
126 | +vbemode:x | ||
127 | + Force the use of VBE mode x. The mode will only be set if it's | ||
128 | + found in the VBE-provided list of supported modes. | ||
129 | + NOTE: The mode number 'x' should be specified in VESA mode number | ||
130 | + notation, not the Linux kernel one (eg. 257 instead of 769). | ||
131 | + HINT: If you use this option because normal <mode> parameter does | ||
132 | + not work for you and you use a X server, you'll probably want to | ||
133 | + set the 'nocrtc' option to ensure that the video mode is properly | ||
134 | + restored after console <-> X switches. | ||
135 | + | ||
136 | +nocrtc Do not use CRTC timings while setting the video mode. This option | ||
137 | + has any effect only if the Video BIOS is VBE 3.0 compliant. Use it | ||
138 | + if you have problems with modes set the standard way. Note that | ||
139 | + using this option implies that any refresh rate adjustments will | ||
140 | + be ignored and the refresh rate will stay at your BIOS default (60 Hz). | ||
141 | + | ||
142 | +noedid Do not try to fetch and use EDID-provided modes. | ||
143 | + | ||
144 | +noblank Disable hardware blanking. | ||
145 | + | ||
146 | +v86d:path | ||
147 | + Set path to the v86d executable. This option is only available as | ||
148 | + a module parameter, and not as a part of the video= string. If you | ||
149 | + need to use it and have uvesafb built into the kernel, use | ||
150 | + uvesafb.v86d="path". | ||
151 | + | ||
152 | +Additionally, the following parameters may be provided. They all override the | ||
153 | +EDID-provided values and BIOS defaults. Refer to your monitor's specs to get | ||
154 | +the correct values for maxhf, maxvf and maxclk for your hardware. | ||
155 | + | ||
156 | +maxhf:n Maximum horizontal frequency (in kHz). | ||
157 | +maxvf:n Maximum vertical frequency (in Hz). | ||
158 | +maxclk:n Maximum pixel clock (in MHz). | ||
159 | + | ||
160 | +4. The sysfs interface | ||
161 | +---------------------- | ||
162 | + | ||
163 | +uvesafb provides several sysfs nodes for configurable parameters and | ||
164 | +additional information. | ||
165 | + | ||
166 | +Driver attributes: | ||
167 | + | ||
168 | +/sys/bus/platform/drivers/uvesafb | ||
169 | + - v86d (default: /sbin/v86d) | ||
170 | + Path to the v86d executable. v86d is started by uvesafb | ||
171 | + if an instance of the daemon isn't already running. | ||
172 | + | ||
173 | +Device attributes: | ||
174 | + | ||
175 | +/sys/bus/platform/drivers/uvesafb/uvesafb.0 | ||
176 | + - nocrtc | ||
177 | + Use the default refresh rate (60 Hz) if set to 1. | ||
178 | + | ||
179 | + - oem_product_name | ||
180 | + - oem_product_rev | ||
181 | + - oem_string | ||
182 | + - oem_vendor | ||
183 | + Information about the card and its maker. | ||
184 | + | ||
185 | + - vbe_modes | ||
186 | + A list of video modes supported by the Video BIOS along with their | ||
187 | + VBE mode numbers in hex. | ||
188 | + | ||
189 | + - vbe_version | ||
190 | + A BCD value indicating the implemented VBE standard. | ||
191 | + | ||
192 | +5. Miscellaneous | ||
193 | +---------------- | ||
194 | + | ||
195 | +Uvesafb will set a video mode with the default refresh rate and timings | ||
196 | +from the Video BIOS if you set pixclock to 0 in fb_var_screeninfo. | ||

221 | + This is the frame buffer driver for generic VBE 2.0 compliant | ||
222 | + graphic cards. It can also take advantage of VBE 3.0 features, | ||
223 | + such as refresh rate adjustment. | ||
224 | + | ||
225 | + This driver generally provides more features than vesafb but | ||
226 | + requires a userspace helper application called 'v86d'. See | ||
227 | + <file:Documentation/fb/uvesafb.txt> for more information. | ||

1726 | + * | ||
1727 | + * Revision history | ||
1728 | + * 7th May 2003 Initial version. | ||
1729 | + * 6th June 2003 Added non module support and AC97 registration. | ||
1730 | + * 18th June 2003 Added AUX adc sampling. | ||
1731 | + * 23rd June 2003 Did some minimal reformatting, fixed a couple of | ||
1732 | + * codec_mutexing bugs and noted a race to fix. | ||
1733 | + * 24th June 2003 Added power management and fixed race condition. | ||
1734 | + * 10th July 2003 Changed to a misc device. | ||
1735 | + * 31st July 2003 Moved TS_EVENT and TS_CAL to wm97xx.h | ||
1736 | + * 8th Aug 2003 Added option for read() calling wm97xx_sample_touch() | ||
1737 | + * because some ac97_read/ac_97_write call schedule() | ||
1738 | + * 7th Nov 2003 Added Input touch event interface, stanley.cai@intel.com | ||
1739 | + * 13th Nov 2003 Removed h3600 touch interface, added interrupt based | ||
1740 | + * pen down notification and implemented continous mode | ||
1741 | + * on XScale arch. | ||
1742 | + * 16th Nov 2003 Ian Molton <spyro@f2s.com> | ||
1743 | + * Modified so that it suits the new 2.6 driver model. | ||
1744 | + * 25th Jan 2004 Andrew Zabolotny <zap@homelink.ru> | ||
1745 | + * Implemented IRQ-driven pen down detection, implemented | ||
1746 | + * the private API meant to be exposed to platform-specific | ||
1747 | + * drivers, reorganized the driver so that it supports | ||
1748 | + * an arbitrary number of devices. | ||
1749 | + * 1st Feb 2004 Moved continuous mode handling to a separate | ||
1750 | + * architecture-dependent file. For now only PXA | ||
1751 | + * built-in AC97 controller is supported (pxa-ac97-wm97xx.c). | ||
1752 | + * 11th Feb 2004 Reduced CPU usage by keeping a cached copy of both | ||
1753 | + * digitizer registers instead of reading them every time. | ||
1754 | + * A reorganization of the whole code for better | ||
1755 | + * error handling. | ||
1756 | + * 17th Apr 2004 Added BMON support. | ||
1757 | + * 17th Nov 2004 Added codec GPIO, codec event handling (real and virtual | ||
1758 | + * GPIOs) and 2.6 power management. | ||
1759 | + * 29th Nov 2004 Added WM9713 support. | ||
1760 | + * 4th Jul 2005 Moved codec specific code out to seperate files. | ||
1761 | + * 6th Sep 2006 Mike Arthur <linux@wolfsonmicro.com> | ||
1762 | + * Added bus interface. | ||
