2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-1417/+0
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

2013-11-07parisc: sticon - unbreak on 64bit kernelHelge Deller1-5/+5
STI text console (sticon) was broken on 64bit machines with more than 4GB RAM and this lead in some cases to a kernel crash. Since sticon uses the 32bit STI API it needs to keep pointers to memory below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel stack) might be above 4GB which then may crash the kernel in the STI functions. Additionally sticon didn't selected the built-in framebuffer fonts by default. This is now fixed. On a side-note: Theoretically we could enhance the sticon driver to use the 64bit STI API. But - beside the fact that some machines don't provide a 64bit STI ROM - this would just add complexity. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org # 3.8+

2007-08-11stifb: detect cards in double buffer mode more reliablyHelge Deller1-7/+12
Visualize-EG, Graffiti and A4450A graphics cards on PARISC can be configured in double-buffer and standard mode, but the stifb driver supports standard mode only. This patch detects double-buffered cards more reliable. It is a real bugfix for a very nasty problem for all parisc users which have wrongly configured their graphic card. The problem: The stifb graphics driver will not detect that the card is wrongly configured and then nevertheless just enables the graphics mode, which it shouldn't. In the end, the user will see no further updates / boot messages on the screen. We had documented this problem already on our FAQ (http://parisc-linux.org/faq/index.html#viseg "Why do I get corrupted graphics with my Vis-EG/Graffiti/A4450A card?") but people still run into this problem. So having this fix in as early as possible can help us.

2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare1-1/+0
I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files. I am fine with removing the untested files from the patch if the general opinion is that these changes aren't safe. The tested part would still be nice to have.

2006-03-31[PATCH] Don't pass boot parameters to argv_init[]OGAWA Hirofumi1-2/+2
The boot cmdline is parsed in parse_early_param() and parse_args(,unknown_bootoption). And __setup() is used in obsolete_checksetup(). start_kernel() -> parse_args() -> unknown_bootoption() -> obsolete_checksetup() If __setup()'s callback (->setup_func()) returns 1 in obsolete_checksetup(), obsolete_checksetup() thinks a parameter was handled. If ->setup_func() returns 0, obsolete_checksetup() tries other ->setup_func(). If all ->setup_func() that matched a parameter returns 0, a parameter is seted to argv_init[]. Then, when runing /sbin/init or init=app, argv_init[] is passed to the app. If the app doesn't ignore those arguments, it will warning and exit. This patch fixes a wrong usage of it, however fixes obvious one only.

2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas1-1/+0
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+1495
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
