* backlight: add backlight typeMatthew Garrett2011-03-221-0/+1
| | | | | | | | | | | | | | | | | | | There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.

* console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn2011-01-261-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

* backlight: constify backlight_opsLionel Debroux2010-11-161-1/+1
| | | | | | | | | | | | backlight_device_register has been expecting a const "ops" argument, and using it as such, since 9905a43b2d563e6f89e4c63c4278ada03f2ebb14. Let's make the remaining backlight_ops instances const. Inspired by hunks of the grsecurity patch, updated for newer kernels.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* radeonfb/aty128fb: Disable broken early resume hook for PowerBooksBenjamin Herrenschmidt2009-03-111-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | radeonfb and aty128fb have a special hook called by the PowerMac platform code very very early on resume from sleep to bring the screen back. This is useful for debugging wakup problems, but unfortunately, this also became a source of problems of its own. The hook is called extremely early, with interrupts still off, and the code path involved with that code nowadays rely on things like taking mutexes, GFP_KERNEL allocations, etc... In addition, the driver now relies on the PCI core to restore the standard config space before calling resume which doesn't happen with this early code path. I'm keeping the code in but commented out along with a fixup call to pci_restore_state(). The reason is that I still want to make it easy to re-enable temporarily to track wake up problems, and it's possible that I can revive it at some stage if we make sleeping things save to call in early resume using a system state. In the meantime, this should fix several reported regressions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have a problem with blanking. The soundcard uses speakers of the monitor. Sound is muted when the screen blanks due to a bug in aty128fb.c. Here is a fragment of linux/fb.h /* VESA Blanking Levels */ #define VESA_NO_BLANKING 0 #define VESA_VSYNC_SUSPEND 1 #define VESA_HSYNC_SUSPEND 2 #define VESA_POWERDOWN 3 enum { /* screen: unblanked, hsync: on, vsync: on */ FB_BLANK_UNBLANK = VESA_NO_BLANKING, /* screen: blanked, hsync: on, vsync: on */ FB_BLANK_NORMAL = VESA_NO_BLANKING + 1, /* screen: blanked, hsync: on, vsync: off */ FB_BLANK_VSYNC_SUSPEND = VESA_VSYNC_SUSPEND + 1, /* screen: blanked, hsync: off, vsync: on */ FB_BLANK_HSYNC_SUSPEND = VESA_HSYNC_SUSPEND + 1, /* screen: blanked, hsync: off, vsync: off */ FB_BLANK_POWERDOWN = VESA_POWERDOWN + 1 }; So FB_BLANK_NORMAL is 1, FB_BLANK_VSYNC_SUSPEND is 2, FB_BLANK_HSYNC_SUSPEND is 3, FB_BLANK_POWERDOWN is 4. And now: blank = FB_BLANK_NORMAL (1) blank & FB_BLANK_HSYNC_SUSPEND (1 & 3) is true, so normal blank caused hsync suspend and sound is muted.

The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it.

| | | | | | | | | | | | | | | | | | | | | | | | | | Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove duplicates of ARRAY_SIZE. Some coding style and trailing whitespaces are also fixed. Compile-tested where possible (some are other arch or BROKEN) Signed-off-by: Tobias Klauser <tklauser@nuerscht.ch> Cc: "Antonino A.

* | [PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt2006-03-281-3/+4
|/ | | | | | | | | | | | | | | | This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

* [PATCH] fbdev: Sanitize ->fb_ioctl prototypeChristoph Hellwig2006-01-141-4/+2
| | | | | | | | | | | The ioctl and file arguments to ->fb_mmap are totally unused and there's not reason a driver should need them. Also update the ->fb_compat_ioctl prototype to be the same as ->fb_mmap.

* [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas2005-11-071-1/+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.

* [PATCH] ppc32: Remove CONFIG_PMAC_PBOOKBenjamin Herrenschmidt2005-06-271-14/+0
| | | | | | | | | | | | This patch removes CONFIG_PMAC_PBOOK (PowerBook support). This is now split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some powerbooks have, CONFIG_PM for power management related code, and just left out of any CONFIG_* option for some generally useful stuff that can be used on non-laptops as well.

* [PATCH] ppc32: Fix AGP and sleep againBenjamin Herrenschmidt2005-04-161-20/+14
| | | | | | | | | | | | | | | | | | | | | | | | My previous patch that added sleep support for uninorth-agp and some AGP "off" stuff in radeonfb and aty128fb is breaking some configs. More specifically, it has problems with rage128 setups since the DRI code for these in X doesn't properly re-enable AGP on wakeup or console switch (unlike the radeon DRM). This patch fixes the problem for pmac once for all by using a different approach. The AGP driver "registers" special suspend/resume callbacks with some arch code that the fbdev's can later on call to suspend and resume AGP, making sure it's resumed back in the same state it was when suspended. This is platform specific for now. It would be too complicated to try to do a generic implementation of this at this point due to all sort of weird things going on with AGP on other architectures. We'll re-work that whole problem cleanly once we finally merge fbdev's and DRI. In the meantime, please apply this patch which brings back some r128 based laptops into working condition as far as system sleep is concerned.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+2485
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!
