2007-07-17fbdev: extract fb_show_logo_line()Geert Uytterhoeven
The Cell Broadband Engine contains a 64-bit PowerPC core with 2 hardware threads (called PPEs) and 8 Synergistic Processing Engines (called SPEs). When booting Linux, 2 penguins logos are shown on the graphical console by the standard frame buffer console logo code. To emphasize the existence of the SPEs (which can be used under Linux), we added a second row of (smaller) helper penguin logos, one for each SPE. A sample screenshot can be found at http://www.kernel.org/pub/linux/kernel/people/geoff/cell/debian-penguin-shot.png (or on the ps3linux T-shirts we wore at OLS :-) This patch: Extract the code to draw one line of logos into fb_show_logo_line() Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Acked-By: James Simmons <jsimmons@infradead.org> Cc: "Antonino A.

2007-07-17Fix the graphic corruption issue on IA64 machinesizumi
VGA console driver can misunderstand the current mode(Text/Graphic) under "disable console blanking" setting. When "disable console blank" is set (blankinterval=0), "do_unblank_screen()" function returns without changing "blank_state", and when "blank_state" is "blank_off", "do_blank_screen() function returns without invoking sw->con_blank() function. That's why VGA console driver can misunderstand the current mode. Signed-off-by: Nobuhiro Tachino <ntachino@redhat.com> Signed-off-by: Taku Izumi <izumi2005@soft.fujitsu.com> Cc: "Antonino A.

2007-07-17fb: epson1355fb: kill off dead sh supportPaul Mundt
The SH board that was the only user for this code was removed entirely from the kernel quite some time ago, so there's no reason to leave the stubs in place. Additionally this driver was completely broken anyways, so there's not really a lot of point in fixing it up either. I can't imagine that this driver gets any testing on ARM either, given that FB_BLANK_UNBLANKING doesn't exist, and kills the build regardless of which platform is compiling. This fixes that, too. It wouldn't be a lot of work to finish the platform device conversion and go with a generic 8-bit read/write_reg and kill off the architecture dependence completely, should someone have any use for this driver.

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().
