Commit 22af89aa0c0b4012a7431114a340efd3665a7617 ("fbcon: replace mono_col macro with static inline") changed the order of operations for computing monochrome color values. This generates 0xffff000f instead of 0x0000000f for a 4 bit monochrome color, leading to image corruption if it is passed to cfb_imageblit or other similar functions. Fix it up.

This reverts commit 2d04a4a72d7e1519b4838f24bdd4b5d0f3f426dc, which made it impossible to make the softcursor use the highlight colors. Yes, the fourth bit should be "blinking", but since we cannot reasonably blink in fbcon, highlighting it with a bright background is preferable.

On HPPA there exists some older GSC graphics cards, which need special graphic-card-BIOS patching to become supported. Since we don't have yet implemented the patching, it's better to detect such cards in advance, inform to the user that there are known problems and to not activate the card. Problematic GSC cards and BIOS versions are: * Hyperdrive/Hyperbowl (A4071A) graphics card series: * ID = 0x2BCB015A (Version 8.04/8) * ID = 0x2BCB015A (Version 8.04/11) * Thunder 1 VISUALIZE 48 card: * ID = 0x2F23E5FC (Version 8.05/9) * Thunder 2 VISUALIZE 48 XP card: * ID = 0x2F8D570E (Version 8.05/12) * Some Hyperion and ThunderHawk GSC cards Further details are described here: http://parisc-linux.org/faq/graphics-howto.html Signed-off-by: Helge Deller <deller@gmx.de> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Krzysztof Helt <krzysztof.h1@poczta.fm> Cc: "Antonino A.

2008-07-24mdacon messing up default vc's - set default to vc13-16 againRoland Kletzing
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). You > will then be able to use two monitors with your Linux system. Do not > say Y here if your MDA card is the primary card in your system; the > normal VGA driver will handle it. 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.

Another addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b ("vt: fix background color on line feed"). fbcon still was not doing the right thing (read: continued to do old behavior). fbcon_clear() seems to clear the new line (e.g. where your new prompt appears after doing echo -en "\e[42mfoo\n"), while scr_memsetw clears the previous one only (where "foo" appears). So just temporarily set the video_erase_char to the scrl_erase_char so that fbcon_clear does the right thing.

2008-04-29vt: fix background color on line feedJan Engelhardt
A command that causes a line feed while a background color is active, such as perl -e 'print "x" x 60, "\e[44m", "x" x 40, "\e[0m\n"' and perl -e 'print "x" x 40, "\e[44m\n", "x" x 40, "\e[0m\n"' causes the line that was started as a result of the line feed to be completely filled with the currently active background color instead of the default color. When scrolling, part of the current screen is memcpy'd/memmove'd to the new region, and the new line(s) that will appear as a result are cleared using memset. However, the lines are cleared with vc->vc_video_erase_char, causing them to be colored with the currently active background color. This is different from X11 terminal emulators which always paint the new lines with the default background color (e.g. `xterm -bg black`). The clear operation (\e[1J and \e[2J) also use vc_video_erase_char, so a new vc->vc_scrl_erase_char is introduced with contains the erase character used for scrolling, which is built from vc->vc_def_color instead of vc->vc_color.

2008-02-06fbcon: fix color generation for monochrome framebufferThomas Pfaff
The current attr_fgcol_ec / attr_bgcol_ec macros do a simple shift of bits to get the color from vc_video_erase_char. For a monochrome display however the attribute does not contain any color, only attribute bits. Furthermore the reverse bit is lost because it is shifted out, the resulting color is always 0. This can bee seen on a monochrome console either directly or by setting it to inverse mode via "setterm -inversescreen on" . Text is written with correct color, fb_fillrects from a bit_clear / bit_clear_margins will get wrong colors. Signed-off-by: Thomas Pfaff <tpfaff@pcs.com> Cc: "Antonino A.

2007-10-16fbcon: delay the start of the cursor timer until a con_switch()Antonino Daplas
As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular cursor can still be seen blinking in the upper left part of the screen. It is fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE, KD_TEXT) call done by something in userspace, perhaps by X itself, while the tty is still in graphics mode. And when the tty is in KD_TEXT mode, the cursor timer is restarted. Although this is a userspace problem, we can work around it by delaying the restart of the cursor timer until an fbcon_switch() is called. In other words, the cursor timer will not be restarted even if a KD_TEXT mode switch is requested.
