mdacon incorrectly detects MDA hardware on systems without such graphics card. One may load this module by chance, for example when doing some systematical module-testing, and if there is no Monochrome Display Adapter attached , module init renders vc1-16 completely unusable. I and others have run into this more than once. see [Bug 224522 - modprobe mdacon freezes machine -> https://bugzilla.novell.com/show_bug.cgi?id=224522 ] for example Apparently proper MDA detection seems to be broken for a long time - seems to be related to those #ifdef TEST_MDA_B statements added by Edward Betts. this commit back in 2002 made things even worse : http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commit;h=c72757b49c88914433244757fb4967fc63546685 It changed default vc allocation from 13-16 to 1-16 for no apparent reason (!?) , and with that (and without X), mdacon grabs the vc you`re currently sitting on and locks you out. this is from Kconfig : >config MDA_CONSOLE > depends on !M68K && !PARISC && ISA > tristate "MDA text console (dual-headed) (EXPERIMENTAL)" > ---help--- > Say Y here if you have an old MDA or monochrome Hercules graphics > adapter in your system acting as a second head ( = video card).

As we can see mdacon is just meant as an additional driver for dual-head setup, and since kernel 2.4.36 still defaults to vc13-16 , setting the default back to that value again shouldn`t do any harm. Hereby i'm reverting that change, setting default back to to vc13-16 again. Besides the fact that mdacon may be rarely or never be used these days and could perhaps put to trash anyway (pre-dinosaur hardware!), indeed this is not a real solution, but at least it removes the unfortunate side-effect of messing up the vc you`re working on.

The tridentfb driver should handle now all chipsets handled by the cyblafb driver. Remove the message which claims that support will be removed. Signed-off-by:

Add imageblit acceleration for the Blade3D family of cores. The code is based on code from the cyblafb driver. It is a step toward assimilating back the cyblafb driver into the tridentfb driver. The cyblafb driver handles a subfamily of the Trident Blade3d cores. Signed-off-by:

This patch fixes following problems: - does not allow the m parameter to reach 0 as it locks the graphics core (power cycle needed) - for the newer chips (with new clock registers) does not allow of n / m ratio below 4 as it gives unstable image on the Blade3D core - extend shift parameter (k) range to 2 for the newer chips to cope with the n /m >= 4 limit at low resolution (bandwidth) modes - prefer modes with higher n / m ratio (higher k values) Signed-off-by:

The Trident cards uses only 20-bit address of screen start in double words. This allows addressing for only 4MB of video memory so check this. Also remove some redundant checks and assignments. Signed-off-by:

Fix depth setting for 8 bpp mode. The nice 224 color logo is not displayed in 8 bpp depth without this fix. Signed-off-by:

This patch fixes two problems when acceleration is enabled: - console switch from the Xorg locks up the computer because the Xorg code locks some registers and disables the mmio mode, so reenable these in the tridentfb_set_par() and enable_mmio() - blacklist the Image975 chipset from setting PCI burst mode. This helps with random lock ups of the framebuffer on this chip. The same fix is probably needed for the Xorg as well. Signed-off-by:

This patch contains general source code improvments: - more simple functions are inline - removes some meaningless output and the VERSION string as it is no use - eng_par is moved into the tridentfb_par - removed small section of code for CyberBladeXPAi1 which is maybe right for only one resolution and refresh rate and is probably redundant now - other minor improvements Signed-off-by:

This patch replaces deprecated constant FB_ACCELF_TEXT with FBINFO_HWACCEL_DISABLED and adds constants for Trident families of accelerators. The FBINFO_HWACCEL_DISABLED is correctly used so noaccel parameter works now. Signed-off-by:

This patch fixes few issues related to timings and pixclock generation: - disallow the pixclocks with numerator lower than double denominator. This fixes display instability for some modes. - choose the pixelclock with the highest numerator and denominator values. This improve image quality and fixes display instability for some modes. - make interlaced modes work. - set synchronization pulses polarization correctly. - horizontal synchronization timing are now the same as generated by X.

This patch fixes two problems when acceleration is enabled: - bit for bitblt direction is corrected so scrolling down works as expected on 3DImage chips - initialization of acceleration is done later this helps with initial console malfuntion (on Blade3D chips) well documented here: http://marc.info/?l=linux-fbdev-users&m=111386953124478&w=2Signed-off-by:

This patch brings various acceleration improvements: - set copyarea/fillrect for non-accelerated framebuffer (fix) - remove 15 bpp depth handling to simplify code as it hardly works (15 bpp handling was obviously missing in some switches) - add fb_sync call and move waiting before accelerated function to make acceleration more asynchronous to cpu (few % of speed improvement) - add cpu_relax() call in waiting loops - make longer register names and name more registers - move registers' definition to header - general code improvements (shortening, simplifying) Signed-off-by:

This patch adds acceleration for TGUI 9440 and 96xx chips. These chips requires line length to be power of 2, so this is also changed. It also moves the troubling enable_mmio() function to its final destination. Signed-off-by:

Improved values for some registers after Xorg Trident driver. The main problem was that values set by BIOS have been ignored. This patch completely remove random pixels ("snow") on the TGUI 9680 and 9440 (not supported yet by the driver). It does not help with the "snow" on 3DImage and Blade3D cards. There is also small improvement in timing calculations (hblank start and vblank start) Signed-off-by: -

Fix broken timings calculations. This patch helps with following problems: - no left part of screen visible (up to half of the screen) - monitor's frequencies are not the ones intended for selected modes - if mode with resoultion y > 1024 is selected at least once then all modes with y < 1024 are "out of sync" (no display) Signed-off-by:

This patch replaces macros with static functions and puts tridentfb_par pointer as the first argument of these functions. These is a step toward multihead support. Additionally, bogus TRIDENT_MMIO define is removed as the driver supports graphics cards only through the mmio mode. Signed-off-by:
