* kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

* vgacon: check for efi machineYannick Heneault2011-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | It seems there is a small problem of VGA palette corruption on EFI machine. When the kernel initializes the architecture, it checks if the machine is a EFI machine and assumes that a VGA console can exist. When it initializes the console in vgacon_startup it checks if it can really use the VGA console. I think this is where a check is missing. Currently, the function can fail if a VESA boot mode is detected but not if a EFI boot mode was used. Thus vgacon_startup() doesn't fail and initialize the video card for a real VGA mode. This function changes the first 16entries of the VGA palette. When the efifb driver kicks in, the palette is not restored to default ramp value, thus the 16 first entry remain in a modified state. The following patch prevent this corruption. Signed-off-by: Yannick Heneault <yheneaul@matrox.com> Cc: Dave Airlie <airlied@linux.ie> Cc: "H.

* vt/console: try harder to print output when panicingJesse Barnes2010-08-101-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Jesse's initial patch commit said: "At panic time (i.e. when oops_in_progress is set) we should try a bit harder to update the screen and make sure output gets to the VT, since some drivers are capable of flipping back to it. So make sure we try to unblank and update the display if called from a panic context." I've enhanced this to add a flag to the vc that console layer can set to indicate they want this behaviour to occur. This also adds support to fbcon for that flag and adds an fb flag for drivers to indicate they want to use the support. It enables this for KMS drivers.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-306-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | | | | | | | | | | | | | | fbcon makes the (reasonable) assumption that it only needs to program the hardware once, when fbcon_init() is called for the foreground console. This doesn't always play well with vgacon because vgacon_deinit() is only doing its job when the last console it owns is closed (when switching from vgacon to fbcon, that's usually *after* fbcon_init() has set the new mode). Depending on the hardware this can cause the wrong framebuffer location to be scanned out (e.g. reproduced on nv05 with the nouveau framebuffer driver).

* fbcon: only unbind from console if successfully registeredIan Armstrong2009-09-231-0/+10
| | | | | | | | | | | | | | | | | | | | | Attempting to unload a framebuffer module calls unregister_framebuffer() which in turn gets fbcon to release it. If fbcon has no framebuffers linked to a console, it will also unbind itself from the console driver. However, if fbcon never registered itself as a console driver, the unbind will fail causing the framebuffer device entry to persist. In most cases this failure will result in an oops when attempting to access the now non-existent device. This patch ensures that the fbcon unbind request will succeed even if a bind was never done. It tracks if a successful bind ever occurred & will only attempt to unbind if needed. If there never was a bind, it simply returns with no error.

* fb: do not ignore fb_set_par errorsFlorian Tobias Schandinat2009-09-231-11/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment about half of the framebuffer drivers can return an error code in fb_set_par. Until now it would be silently ignored by fbmem.c and fbcon.c. This patch fixes fbmem.c to return the error code and restore var on error. But it is not clear in which video mode the device is when fb_set_par fails. It would be good and reasonable if it were in the old state but there is no guarantee that this is true for all existing drivers. Additionally print a message if a failing fb_set_par is detected in fbmem.c or fbcon.c. Although most errors should be caught by the previous fb_check_var some errors can't as they are dynamic (memory allocations, ...) and can only be detected while performing the operations which is forbidden in fb_check_var. This patch shouldn't have a negative impact on normal operation as all drivers return 0 on success. The impact in case of error depends heavily on the driver and caller but it's expected to be better than before.

* sparc: Kill PROM console driver.David S. Miller2009-09-165-631/+1
| | | | | | | | | | | | | | | | Many years ago when this driver was written, it had a use, but these days it's nothing but trouble and distributions should not enable it in any situation. Pretty much every console device a sparc machine could see has a bonafide real driver, making the PROM console hack unnecessary. If any new device shows up, we should write a driver instead of depending upon this crutch to save us. We've been able to take care of this even when no chip documentation exists (sunxvr500, sunxvr2500) so there are no excuses. Signed-off-by: David S. Miller <davem@davemloft.net>
* fbcon: don't use vc_resize() on initializationJohannes Weiner2009-08-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Catalin and kmemleak spotted a leak of a VC screen buffer in vc_allocate() due to the following chain of events: vc_allocate() visual_init(init=1) vc->vc_sw->con_init(init=1) fbcon_init() vc_resize() vc->screen_buf = kmalloc() vc->screen_buf = kmalloc() The common way for the VC drivers is to set the screen dimension parameters manually in the init case and only call vc_resize() for !init - which allocates a screen buffer according to the new dimensions. fbcon instead would do vc_resize() unconditionally and afterwards set the dimensions manually (again) for !init - i.e. completely upside down. The vc_resize() allocated buffer would then get lost by vc_allocate() allocating a fresh one. Use vc_resize() only for actual resizing to close the leak. Set the dimensions manually only in initialization mode to remove the redundant setting in resize mode.

* vgacon: return the upper half of 512 character fontsStefan Bader2009-05-031-1/+1
| | | | | | | | | | | | | | | | | | | | | Uwe Geuder noted that he gets random bitmaps on a text console if he tried to type extended characters (like the e acute). For him everything above unicode 0xa0 was corrupted. After some digging there seems to be a little culprit in vgacon since the beginning of ages (well git). The function vgacon_font_get will store the number of characters correctly in font->charcount but then calls to vgacon_do_font_op(..., 0, 0). Which means only the lower 256 characters are actually stored to the fontdata. The rest is left untouched. So the next time that saved data is used, the garbled font appears. This happens on every switch between text consoles.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add mode setting support to the DRM layer. This is a fairly big chunk of work that allows DRM drivers to provide full output control and configuration capabilities to userspace. It was motivated by several factors: - the fb layer's APIs aren't suited for anything but simple configurations - coordination between the fb layer, DRM layer, and various userspace drivers is poor to non-existent (radeonfb excepted) - user level mode setting drivers makes displaying panic & oops messages more difficult - suspend/resume of graphics state is possible in many more configurations with kernel level support This commit just adds the core DRM part of the mode setting APIs. Driver specific commits using these new structure and APIs will follow.

* fbcon: fix workqueue shutdownGeoff Levand2008-12-101-0/+6
| | | | | | | | | | | | | | | | | | | | | | | Add a call to cancel_work_sync() in fbcon_exit() to cancel any pending work in the fbcon workqueue. The current implementation of fbcon_exit() sets the fbcon workqueue function info->queue.func to NULL, but does not assure that there is no work pending when it does so. On occasion, depending on system timing, there will still be pending work in the queue when fbcon_exit() is called. This results in a null pointer deference when run_workqueue() tries to call the queue's work function.

* fbdev: fix FB console blankingDmitry Baryshkov2008-12-021-6/+3
| | | | | | | | | | | | | | | | | | | | | | | The commit aef7db4bd5a3b6068dfa05919a3d685199eed116 fixed the problem with recursive locking in fb blanking code if blank is caused by user setting the /sys/class/graphics/fb*/blank. However this broke the fbcon timeout blanking. If you use a driver that defines ->fb_blank operation and at the same time that driver relies on other driver (e.g. backlight or lcd class) to blank the screen, when the fbcon times out and tries to blank the fb, it will call only fb driver blanker and won't notify the other driver. Thus FB output is disabled, but the screen isn't blanked. Restore fbcon blanking and at the same time apply the proper fix for the above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are already called through notification from fb_blank, thus we don't have to blank the fb again.
