* [PATCH] pmac/radeonfb: Add suspend support for M11 chip in new iBook 12"Sven Henkel2005-10-011-6/+8
| | | | | | | | | | | | | | | This adds suspend support for the Radeon M11 chip in 12" iBooks manufactured after July 2005. I don't know if the new 14" iBooks also have that chip, so they might also be supported. The chip identifies itself as "RV350 NV" (pci id 0x4e56), revision 0x80. Apple calls it "Snowy", xfree86 names it "ATI FireGL Mobility T2 (M11) NV (AGP)". So, we seem to be lucky here: The suspend-code for the M10 (which also is a "RV350 NV") works flawless for that chip.

| | | | | | | | | | | | | | | | | | | | The driver does a readl() on DEVICE_ID which is 2-byte aligned and 2-bytes in size. It's doing this read just to flush write buffers.

| | | | | | | | | | | | | | | | | | | | Reported by: walt <wa1ter@myrealbox.com> "I routinely switch the console font during bootup to 8x8 so I can get 50 lines per screen. Until 09 Sept, just changing to the small font automatically gave me all 50 lines -- but now I'm only getting 25 lines even with the small font. The bottom half of the screen displays the text that already scrolled off the top." This bug is due to an erroneous check in the recently added hook, vgacon_resize(). It checks the new height against the original number of rows of the console. Because the original number of rows depends on both the scanline and the font height, check it instead against the scanline/fontheight.

* [PATCH] USB: sisusb[vga] updateThomas Winischhofer2005-09-122-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | here is a new and extended version of the sisusbvga (previously: sisusb) driver. The patch is against 2.6.13 and updates the driver to version 0.0.8. Additions include complete VGA/EGA text console support and a build-in display mode infrastructure for userland applications that don't know about the graphics internals. Fixes include some BE/LE issues and a get/put_dev bug in the previous version. Other changes include a change of the module name from "sisusb" to "sisusbvga". The previous one was too generic IMHO. Please note that the patch also affects the Makefile in drivers/video/console as the driver requires the VGA 8x16 font in case the text console part is selected. Heavily tested, as usual. Please apply. One thing though: I already prepared for removal of the "mode" field and the changed "name" field in the usb_class_driver structure. This will perhaps need some refinement depending on whether you/Linus merge the respective core changes before or after 2.6.14.

* [PATCH] i810fb: Change option ext_vga to extvga to match documentationAntonino A. Daplas2005-09-111-6/+6
| | | | | | | | | | | | | | | Reported by: Manuel Lauss <mano@roarinelk.homelinux.net> He was getting random initial video modes depending on the kernel configuration. His option line includes 'extvga'. The i810fb documentation describes the option 'extvga', however the driver accepts 'ext_vga'. Besides 'extvga' being ignored by i810fb, it also confuses the option parser of i810fb and assigns 'extvga' to 'mode_option'. This leads to an incorrect video mode at boot time.

* [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] 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>

* [PATCH] sisfb updateThomas Winischhofer2005-09-0920-18373/+14226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This lifts sisfb from version 1.7.17 to version 1.8.9. 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.
