* [PATCH] md: tidy up daemon stop/start code in md/bitmap.cNeilBrown2005-09-102-47/+28Star
| | | | | | | | | | | | The bitmap code used to have two daemons, so there is some 'common' start/stop code. But now there is only one, so the common code is just noise. This patch tidies this up somewhat.

* [PATCH] md: ensure bitmap_writeback_daemon handles shutdown properly.NeilBrown2005-09-101-0/+3
| | | | | | | | | | mddev->bitmap gets clearred before the writeback daemon is stopped. So the write_back daemon needs to be careful not to dereference the 'bitmap' if it is NULL.

* [PATCH] md: add write-intent-bitmap support to raid5NeilBrown2005-09-102-12/+124
| | | | | | | | | | | | | | | | | | | | | | | Most awkward part of this is delaying write requests until bitmap updates have been flushed. To achieve this, we have a sequence number (seq_flush) which is incremented each time the raid5 is unplugged. If the raid thread notices that this has changed, it flushes bitmap changes, and assigned the value of seq_flush to seq_write. When a write request arrives, it is given the number from seq_write, and that write request may not complete until seq_flush is larger than the saved seq number. We have a new queue for storing stripes which are waiting for a bitmap flush and an extra flag for stripes to record if the write was 'degraded' and so should not clear the a bit in the bitmap.

* [PATCH] md: limit size of sb read/written to appropriate amountNeilBrown2005-09-101-5/+15
| | | | | | | | | | | | | version-1 superblocks are not (normally) 4K long, and can be of variable size. Writing the full 4K can cause corruption (but only in non-default configurations). With this patch the super-block-flavour can choose a size to read, and set a size to write based on what it finds.

| | | | | | | | | | | | | | | It is possibly (and occasionally useful) to have a raid1 without persistent superblocks. The code in add_new_disk for adding a device to such an array always tries to read a superblock. This will obviously fail. So do the appropriate test and call md_import_device with appropriate args.

| | | | | | | | | | | | When hot-adding a bitmap, bitmap_daemon_work could get called while the bitmap is being created, so don't set mddev->bitmap until the bitmap is ready.

| | | | | | | | | | | | | | | linear currently uses division by the size of the smallest componenet device to find which device a request goes to. If that smallest device is larger than 2 terabytes, then the division will not work on some systems.

* [PATCH] md: add write-behind support for md/raid1NeilBrown2005-09-102-11/+139
| | | | | | | | | | | | | | | | | | | If a device is flagged 'WriteMostly' and the array has a bitmap, and the bitmap superblock indicates that write_behind is allowed, then write_behind is enabled for WriteMostly devices. Write requests will be acknowledges as complete to the caller (via b_end_io) when all non-WriteMostly devices have completed the write, but will not be cleared from the bitmap until all devices complete. This requires memory allocation to make a local copy of the data being written. If there is insufficient memory, then we fall-back on normal write semantics.

* | [PATCH] fbdev: Add VESA Coordinated Video Timings (CVT) supportAntonino A. Daplas2005-09-094-11/+446
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Coordinated Video Timings (CVT) is the latest standard approved by VESA concerning video timings generation. It addresses the limitation of GTF which is designed mainly for CRT displays. CRT's have a high blanking requirement (as much as 25% of the horizontal frame length) which artificially increases the pixelclock. Digital displays, on the other hand, needs to conserve the pixelclock as much as possible. The GTF also does not take into account the different aspect ratios in its calculation. The new function added is fb_find_mode_cvt(). It is called by fb_find_mode() if it recognizes a mode option string formatted for CVT. The format is: <xres>x<yres>[M][R][-<bpp>][<at-sign><refresh>][i][m] The 'M' tells the function to calculate using CVT. On it's own, it will compute a timing for CRT displays at 60Hz. If the 'R' is specified, 'reduced blanking' computation will be used, best for flatpanels. The 'i' and the 'm' is for 'interlaced mode' and 'with margins' respectively. To determine if CVT was used, check for dmesg for something like this: CVT Mode - <pix>M<n>[-R], ie: .480M3-R (800x600 reduced blanking) where: pix - product of xres and yres, in MB M - is a CVT mode n - the aspect ratio (3 - 4:3; 4 - 5:4; 9 - 16:9, 15:9; A - 16:10) -R - reduced blanking Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | [PATCH] radeonfb: Only request resources we needDaniel Burcaw2005-09-091-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes radeon to request only resources 0 and 2 instead of all 3. This works around problems with some setups where BAR 1 (IO BAR) has not been assigned by the firmware since it's not used on the machine and the kernel fails to assign something to it due to the card being between a P2P bridge that was configured without an IO range at all.

* | [PATCH] framebuffer: bit_putcs() optimization for 8x* fontsKnut Petersen2005-09-091-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This trivial patch gives a performance boost to the framebuffer console Constructing the bitmaps that are given to the bitblit functions of the framebuffer drivers is time consuming. Here we avoide a call to the slow fb_pad_aligned_buffer(). The patch replaces that call with a simple but much more efficient bytewise copy. The kernel spends a significant time at this place if you use 8x* fonts. Every pixel displayed on your screen is prepared here. Some benchmark results: Displaying a file of 2000 lines with 160 characters each takes 889 ms system time using cyblafb on my system (I´m using a 1280x1024 video mode, resulting in a 160x64 character console) Displaying the same file with the enclosed patch applied to 2.6.13 only takes 760 ms system time, saving 129 ms or 14.5%. Font widths other than 8 are not affected. The advantage and correctness of this patch should be obvious.

* | [PATCH] framebuffer: new driver for cyberblade/i1 graphics coreKnut Petersen2005-09-094-2/+1493
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a framebuffer driver for the Cyberblade/i1 graphics core. Currently tridenfb claims to support the cyberblade/i1 graphics core. This is of very limited truth. Even vesafb is faster and provides more working modes and a much better quality of the video signal. There is a great number of bugs in tridentfb ... but most often it is impossible to decide if these bugs are real bugs or if fixing them for the cyberblade/i1 core would break support for one of the other supported chips. Tridentfb seems to be unmaintained,and documentation for most of the supported chips is not available. So "fixing" cyberblade/i1 support inside of tridentfb was not an option, it would have caused numerous if(CYBERBLADEi1) else ... cases and would have rendered the code to be almost unmaintainable. A first version of this driver was published on 2005-07-31. A fix for a bug reported by Jochen Hein was integrated as well as some changes requested by Antonino A. Daplas. A message has been added to tridentfb to inform current users of tridentfb to switch to cyblafb if the cyberblade/i1 graphics core is detected. This patch is one logical change, but because of the included documentation it is bigger than 70kb. Therefore it is not sent to lkml and linux-fbdev-devel, Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Cc: Muli Ben-Yehuda <mulix@mulix.org> Acked-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Changes include: - Added support for XGI V3XT, V5, V8, Z7 chipsets, including POSTing of all of these chipsets. - Added support for latest SiS chipsets (761). - Added support for SiS76x memory "hybrid" mode. - Added support for new LCD resolutions (eg 1280x854, 856x480). - Fixed support for 320x240 STN panels (for embedded devices). - Fixed many HDTV modes (525p, 750p, 1080i). - Fixed PCI config register reading/writing to use proper kernel functions for this purpose. - Fixed PCI ROM handling to use the kernel's proper functions. - Removed lots of "typedef"s. - Removed lots of code which was for X.org/XFree86 only. - Fixed coding style in many places. - Removed lots of 2.4 cruft. - Reduced stack size by unifying two previously separate structs into one. - Added new hooks for memory allocation (for DRM). Now the driver can truly handle multiple cards, including memory management. - Fixed numerous minor bugs. Signed-off-by: Thomas Winischhofer <thomas@winischhofer.net> Cc: "Antonino A.
