* fbcon: prevent cursor disappearance after switching to 512 character fontKrzysztof Helt2008-08-12
| | | | | | | | | | | | | Adjust and honor the vc_scrl_erase_char for 256 and 512 character fonts. It fixes the issue with disappearing cursor during scrolling (http://bugzilla.kernel.org/show_bug.cgi?id=11258). The issue was reported and tracked by Peter Hanzel.

* Revert "fbcon: bgcolor fix"Linus Torvalds2008-08-11
| | | | | | | | | | | | | | 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.

* | sticore: don't activate unsupported GSC STI cards on HPPAHelge Deller2008-07-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mdacon messing up default vc's - set default to vc13-16 againRoland Kletzing2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

So just temporarily set the video_erase_char to the scrl_erase_char so that fbcon_clear does the right thing.

* vt: fix background color on line feedJan Engelhardt2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* fbcon: fix color generation for monochrome framebufferThomas Pfaff2008-02-06
| | | | | | | | | | | | | | | | | | 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.

* fbcon: delay the start of the cursor timer until a con_switch()Antonino Daplas2007-10-16
| | | | | | | | | | | | | | | | | | | | 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.

* vt/vgacon: Check if screen resize request comes from userspaceAntonino A. Daplas2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* fbdev: fbcon: console unregistration from unregister_framebufferJesse Barnes2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* fbcon: allow fbcon to use the primary display driverAntonino A. Daplas2007-07-17
| | | | | | | | | | | | | | | | 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.
