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.

2008-05-13vt/fbcon: fix background color on line feedJan Engelhardt
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.

2007-10-16vt/vgacon: Check if screen resize request comes from userspaceAntonino A. Daplas
Various console drivers are able to resize the screen via the con_resize() hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that con_resize() of the VGA console will always return success even if the resulting screen is not compatible with the hardware. However, this particular behavior of the VGA console, as reported in Kernel Bugzilla Bug 7513, can cause undefined behavior if the user starts with a console size larger than 80x25. To work around this problem, add an extra parameter to con_resize(). This parameter is ignored by drivers except for vgacon. If this parameter is non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl and vgacon will always return success. If this parameter is zero, vgacon will return -EINVAL if the requested size is not compatible with the hardware. The latter is the more correct behavior. With this change, SVGATextMode should still work correctly while in-kernel and stty resize calls can expect correct behavior from vgacon.

2007-07-17fbdev: fbcon: console unregistration from unregister_framebufferJesse Barnes
This allows for proper console unregistration via the VT layer, and updates the FB layer to use it. This makes debugging new console drivers much easier, since you can properly clean them up before unloading. [adaplas] unregister_framebuffer() is typically called as part of the driver's module_exit(). Doing so otherwise will freeze the machine as the VT layer is holding reference counts on fbcon, and fbcon on the driver. With this change, it allows unregister_framebuffer() to be called safely anywhere as needed. Additions from the original: If multiple drivers are used by fbcon, and if one of them unregisters, a driver will take over the consoles vacated by the outgoing one (via set_con2fb_map). Once only the outgoing driver remains, then fbcon will unbind from the VT layer (if CONFIG_HW_CONSOLE_UNBINDING is set to y). It is important that these drivers implement fb_open() and fb_release() just to ensure that no other process is using the driver. Likewise, these drivers _must_ check the return value of unregister_framebuffer().

Trying to do a set_con2fb_map() on a non-allocated vc will freeze the system. - ensure that succeeding drivers after the first gets mapped to the console - remove fbcon_preset_display() and modify fbcon_set_display() to include the former's functionality - ensure that binding and unbinding succeeds if multiple drivers are mapped to the console Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-17fbcon: allow fbcon to use the primary display driverAntonino A. Daplas
Allow fbcon to select the primary display adapter using the fb_is_primary_device() arch-specific helper. If a a primary adapter is detected, fbcon will unbind the old adapter from the VT layer, then rebind using the new adapter. This requires that bind_/unbind_con_driver() be made public. Because this feature may produce unexpected behavior (from the user's POV), this must be explicitly enabled in Kconfig.

2007-07-17fbcon: cursor blink controlAntonino A. Daplas
Add sysfs attribute to enable or disable cursor blinking. This will also disable cursor blinking if the VT layer's softcursor is active. These changes are required to enable some machines to enter low-power states properly.

2007-07-17fbcon: smart blitter usage for scrollingKrzysztof Helt
This patch replaces the current SCROLL_MOVE method with smarter method using the same logic as the SCROLL_REDRAW method. This brings these two methods much closer in performance and benefits all framebuffers which uses the SCROLL_MOVE method.

2007-06-04[VIDEO]: Fix section mismatch warning in promcon.Sam Ravnborg
Fix the following warnings in promcon: WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x480): Section mismatch: reference to .init.data:promfont_unitable (between 'promcon_init_unimap' and 'promcon_init') WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x488): Section mismatch: reference to .init.data:promfont_unitable (between 'promcon_init_unimap' and 'promcon_init') WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x48c): Section mismatch: reference to .init.data:promfont_unicount (between 'promcon_init_unimap' and 'promcon_init') WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x490): Section mismatch: reference to .init.data:promfont_unicount (between 'promcon_init_unimap' and 'promcon_init') The warnings happens because the function: promcon_init_unimap() references promfont_unitable and promfont_unicount which are marked __initdata by the conmakehash command in the drivers/video/console/Makefile Fix the warning by removing the __initdata marker on the two variables.
