Use schedule_timeout_interruptible() instead of set_current_state()/schedule_timeout() to reduce kernel size. Also use human-time conversion functions instead of hard-coded HZ division to avoid rounding errors. Signed-off-by:

This patch splits dentry locking documentation from Documentation/filesystems/vfs.txt to a separate file. The dentry locking bits are useful but do not fit into the VFS overview document as is. Signed-off-by:

This patch updates the Documentation/filesystems/vfs.txt document. I rearranged and rewrote parts of the introduction chapter and added better headings for each section. I also added a description for the inode rename() operation which was missing and added links to some useful external VFS documentation. Signed-off-by:

Convert to proper kernel-doc format. Some have extra blank lines (not allowed immed. after the function name) or need blank lines (after all parameters). Function summary must be only one line. Colon (":") in a function description does weird things (causes kernel-doc to think that it's a new section head sadly). Signed-off-by: -

I've recently added this documentation, Alasdair gave some corrections, and here are some further corrections on top of his work (partly style issue, partly a technical error due to different past experience, partly a note which I've added - i.e. transient snapshots are lighter).

The current init code sets hiprilvl to 0 and maxhipri to 5. According to the specs those values are illegal on both G200 and G400. It also causes distortions on the TV-out at least when CRTC2 is in YUV mode as is the case with DirectFB. This patch resets both values to 0. Signed-off-by:

Use the CACHEFLUSH register on all chip types. The register is listed in all other specs except 2064W. However I have verified that the register does work on a 2064W despite being marked reserved in the specs. There were no noticeable side effects after writing to the register. Signed-off-by:

Add new entries for Mystique AGP with the PCI ID 0x051e. I don't actually have such boards but according to google they do exist. Curiosly X.Org doesn't recognize that PCI ID. And what's even more interesting is that Matrox's own Windows drivers don't recognize it either. After going through about a dozen different versions I did find one older driver that does list this particular ID. It is also listed in the pci.ids file. I'm not sure if non-220 AGP chips exist. I left the chip revision check intact for AGP chips nonetheless. Signed-off-by:

Antonino A. Daplas authored
Add new helper, fb_find_best_display(), which will search the modelist for the best mode for the attached display. This requires an EDID block that is converted to struct fb_monspecs and a private modelist. The search will be done in this manner: - if 1st detailed timing is preferred, use that - else if dimensions of the display are known, use that to estimate xres and - else if modelist has detailed timings, use the first detailed timing - else, use the very first entry from the modelist Signed-off-by:

I converted the "rl" console font from the kbd utility to be a built-in font for the framebuffer console, and I was wondering if you would be OK with including it. I've generated a font_rl.c file and related minor modifications. I find it's the most visually appealing of the kbd fonts which is why I use it and selected it for conversion. I believe the font is GPL'd. Signed-off-by:

Currently the fb_find_nearest_mode() function finds a mode with screen resolution closest to that described by the 'var' argument and with some arbitrary refresh rate (eg. in the following sequence of refresh rates: 70 60 53 85 75, 53 is selected). This patch fixes the function so that it looks for the closest mode as far as both resolution and refresh rate are concerned. The function's first argument is changed to fb_videomode so that the refresh rate can be specified by the caller, as fb_var_screeninfo doesn't have any fields that could directly hold this data.

Reported by: Jean-Philippe Guérard (Bugzilla Bug 1782) "I've tried with video=atyfb:debug and video=atyfb:debug,mode:1280x600, \ nomtrr. In both case, the screen stays black, but seems divided into 4 vertical bands. Some white lines pop up randomly on each vertical band." The problem is a combination of an incorrect xclk plus lack of timing information. The adapter is attached to an LCD device that can do 1280x600 (which is not a standard resolution). The global mode database does not have an entry for it. Fortunately, the Video BIOS contains the complete timing info for this display, however, atyfb is not making use of it. Add support to get the timing information from the BIOS, if available. Signed-off-by:

If machine has more than 1 driver installed, and they all drive the same hardware, it's possible that the driver's fb_release() method will attempt to restore the hardware state to the initial state. This will leave the new driver in an undefined state. To prevent this problem, initialize the new driver by calling fb_set_par() when the old driver is released by fbcon.
