2006-04-27[PATCH] Frame buffer: remove cmap sysfs interfaceJon Smirl
Remove it as it does not work properly due to sysfs core changes. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-03-27[PATCH] framebuffer: cmap-setting return valuesAlan Curry
A set of 3 small bugfixes, all of which are related to bogus return values of fb colormap-setting functions. First, fb_alloc_cmap returns -1 if memory allocation fails. This is a hard condition to reproduce since you'd have to be really low on memory, but from studying the contexts in which it is called, I think this function should be returning a negative errno, and the -1 will be seen as an EPERM. Switching it to -ENOMEM makes sense. Second, the store_cmap function which is called for writes to /sys/class/graphics/fb0/color_map returns 0 for success, but it should be returning the count of bytes written since its return value ends up in userspace as the result of the write() syscall. Third, radeonfb returns 1 instead of a negative errno when FBIOPUTCMAP is called with an oversized colormap. This is seen in userspace as a return value of 1 from the ioctl() syscall with errno left unchanged. A more useful return value would be -EINVAL.

2005-11-09[PATCH] fbcon: Console Rotation - Add ability to control rotation via sysfsAntonino A. Daplas
Add ability to set rotation via sysfs. The attributes are located in /sys/class/graphics/fb[n] and accepts 0 - unrotated; 1 - clockwise; 2 - upside down; 3 - counterclockwise. The attributes are: con_rotate (r/w) - set rotation of the active console con_rotate_all (w) - set rotation of all consoles rotate (r/w) - set rotation of the framebuffer, if supported. Currently, none of the drivers support this. This is probably temporary, since con_rotate and con_rotate_all are console-specific and has no business being under the fb device. However, until the console layer acquires it's own sysfs class, these attributes will temporarily reside here.

2005-07-27[PATCH] fbdev: colormap fixesJon Smirl
Color maps have up to 256 entries. 4096/256 allows for 16 characters per line. The format for a cmap entry is "%02x%c%4x%4x%4x\n" %02x entry %c transp %4x red %4x blue %4x green You can read the color_map with cat fb0/color_map.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
