* OMAP: DSS2: OMAPFB: Reduce stack usageTomi Valkeinen2011-05-121-34/+61
| | | | | | | | | | omapfb_mode_to_timings() had struct fb_info, struct fb_var and struct fb_ops allocated from stack. This caused the stack usage grow quite high. Use kzalloc to allocate the structs instead. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* OMAP: DSS2: OMAPFB: make DBG() more resistant in if-else constructionsNiels de Vos2011-05-111-2/+4
| | | | | | | | | | When DBG() is used in a simple if-else, the resulting code path currently depends on the definition of DBG(). Inserting the statement in a "do { ... } while (0)" prevents this possible misuse.

| | | | | | | | | | | Convert simple/strict_strto* functions to kstrto* functions. Only simple cases are converted. simple_strto* uses are still left to places where it is used to parse numbers from a list of numbers. These need some other solution than kstrto*.

* OMAP: DSS2: OMAPFB: Remove implicit display update on unblankJani Nikula2011-05-111-13/+0
| | | | | | | | | | | | | | | | Currently omapfb does an implicit display update (for manual update displays) on unblank. There is no guarantee that the framebuffer contains a valid image when unblank is called. When using manual update displays it is the responsibility of the user space to update the display, and so it should be in this case also. This patch removes the implicit display update on unblank.

* OMAPFB: Adding a check for timings in set_def_modeJanorkar, Mayuresh2011-03-111-7/+16
| | | | | | | | | | | | | | | | | | | When omapfb.mode is passed through bootargs, when omapfb is setting mode, it would check if timings passed are fine for panel attached to it. It makes use of check_timing API provided by the panel. In current code if check_timing API is not available for attached panel, OMAPFB would return -EINVAL and BPP sent via bootargs will not have any effect. In case of panels like TAAL panel, omapfb or any other driver should not be allowed to change the timings. So bpps sent via bootargs will not have an effect. In such case we can check only the x_res and y_res with the panels resolution and if they match go ahead and set the bpps. The bpp value sent via bootarg would have an effect.

* OMAP: DSS2: OMAPFB: Add support for switching memory regionsVille Syrjälä2010-08-034-63/+179
| | | | | | | | | | | | | | | | | Separate the memory region from the framebuffer device a little bit. It's now possible to select the memory region used by the framebuffer device using the new mem_idx parameter of omapfb_plane_info. If the mem_idx is specified it will be interpreted as an index into the memory regions array, if it's not specified the framebuffer's index is used instead. So by default each framebuffer keeps using it's own memory region which preserves backwards compatibility. This allows cloning the same memory region to several overlays and yet each overlay can be controlled independently since they can be associated with separate framebuffer devices.

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