2009-01-04viafb: fix crashes due to 4k stack overflowBruno Prémont
The function viafb_cursor() uses 2 stack-variables of CURSOR_SIZE bits; CURSOR_SIZE is defined as (8 * 1024). Using up twice 1k on stack is too much for 4k-stack (though it works with 8k-stacks). Make those two variables kzalloc'ed to preserve stack space. Also merge the whole lot of local struct's in viafb_ioctl into a union so the stack usage gets minimized here as well. (struct's are only accessed in their indicidual IOCTL case) This second part is only compile-tested as I know of no userspace app using the IOCTLs.

2008-12-29[ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devicesEric Miao
PXA27x and later processors support overlay1 and overlay2 on-top of the base framebuffer (although under-neath the base is also possible). They support palette and no-palette RGB formats, as well as YUV formats (only available on overlay2). These overlays have dedicated DMA channels and behave in a similar way as a framebuffer. This heavily simplified and re-structured work is based on the original pxafb_overlay.c (which is pending for mainline merge for a long time). The major problems with this pxafb_overlay.c are (if you are interested in the history): 1. heavily redundant (the control logics for overlay1 and overlay2 are actually identical except for some small operations, which are now abstracted into a 'pxafb_layer_ops' structure) 2. a lot of useless and un-tested code (two workarounds which are now fixed on mature silicons) 3. cursorfb is actually useless, hardware cursor should not be used this way, and the code was actually un-tested for a long time. The code in this patch should be self-explanatory, I tried to add minimum comments. As said, this is basically simplified, there are several things still on the pending list: 1. palette mode is un-supported and un-tested (although re-using the palette code of the base framebuffer is actually very easy now with previous clean-up patches) 2. fb_pan_display for overlay(s) is un-supported 3. the base framebuffer can actually be abstracted by 'pxafb_layer' as well, which will help further re-use of the code and keep a better and consistent structure. (This is the reason I named it 'pxafb_layer' instead of 'pxafb_overlay' or something alike) See Documentation/fb/pxafb.txt for additional usage information.

2008-12-29[ARM] pxafb: cleanup of the color format manipulation codeEric Miao
1. introduce var_to_depth() to calculate the color depth including the transparency bit 2. the conversion from 'fb_var_screeninfo' to LCCR3 BPP bits can be re- used by overlays (in OVLxC1), thus an individual pxafb_var_to_bpp() has been separated out. 3. pxafb_setmode() should really set the color bitfields correctly at begining, introduce a pxafb_set_pixfmt() for this 4. allow user apps to specify color formats within fb_var_screeninfo, and checking of this in pxafb_check_var() has been simplified as below: a) pxafb_var_to_bpp() should pass - which means a basically correct bits_per_pixel and color depth setting b) the RGBT bitfields are then forced into supported values by pxafb_set_pixfmt() Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Eric Miao <ycmiao@ycmiao-hp520.(none)>

2008-12-29[ARM] pxafb: add support for FBIOPAN_DISPLAY by dma brachingEric Miao
dma branching is enabled by extending the current setup_frame_dma() function to allow a 2nd set of frame/palette dma descriptors to be used. As a result, pxafb_dma_buff.dma_desc[], pxafb_dma_buff.pal_desc[] and pxafb_info.fdadr[] are doubled. This allows maximum re-use of the current dma setup code, although the pxafb_info.fdadr[xx] for FBRx register values looks a bit odd.

2008-12-29[ARM] pxafb: allow pxafb_set_par() to start from arbitrary yoffsetEric Miao
Note the var->yres_virtual is only re-calculated from the fix.smem_len when text mode acceleration is enabled (which is default), this is due to the issue as Russell suggested below: Previous experience of doing this with the X server and acornfb is that it causes all sorts of problems - it seems to force the X server into assuming that the framebuffer should be panned no matter what settings you ask it for. The recommended workaround (implemented in acornfb) is to only do these kinds of adjustments if text mode acceleration is enabled. IIRC, the X server should be disabling text mode acceleration when it maps the framebuffer. I seem to remember that there are X servers which forget to do that though.

2008-12-29[ARM] pxafb: allow video memory size to be configurableEric Miao
The amount of video memory size is decided according to the following order: 1. <xres> x <yres> x <bits_per_pixel> by default, which is the backward compatible way 2. size specified in platform data 3. size specified in module parameter 'options' string or specified in kernel boot command line (see updated Documentation/fb/pxafb.txt) And now since the memory is allocated from system memory, the pxafb_mmap can be removed and the default fb_mmap() should be working all right. Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA descriptors and palettes, the allocation can be separated cleanly. NOTE: the LCD DMA actually supports chained transfer (i.e. page-based transfers), to simplify the logic and keep the performance (with less TLB misses when accessing from memory mapped user space), the memory is allocated by alloc_pages_*() to ensures it's physical contiguous.

2008-12-29DRM: add mode setting supportDave Airlie
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.

2008-12-22video: sh_mobile_lcdcfb deferred io supportMagnus Damm
This patch adds sh_mobile_lcdcfb deferred io support for SYS panels. The LCDC hardware block managed by the sh_mobile_lcdcfb driver supports RGB or SYS panel configurations. SYS panels come with an external display controller that is resposible for refreshing the actual LCD panel. RGB panels are controlled directly by the LCDC and they need to be refreshed by the LCDC hardware. In the case of SYS panels we can save some power by configuring the LCDC hardware block in one-shot mode. In this one-shot mode panel refresh is managed by software. This works well together with deferred io since it allows us to stop clocks for most of the time and only enable clocks when we actually want to trigger an update. When there is no fbdev activity the clocks are kept stopped which allows us to deep sleep. The refresh rate in deferred io mode is set using platform data. The same platform data can also be used to disable deferred io mode. As with other deferred io frame buffers user space code should use fsync() on the frame buffer device to trigger an update.

2008-12-21powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDEDBenjamin Herrenschmidt
Currently, we never set _PAGE_COHERENT in the PTEs, we just OR it in in the hash code based on some CPU feature bit. We also manipulate _PAGE_NO_CACHE and _PAGE_GUARDED by hand in all sorts of places. This changes the logic so that instead, the PTE now contains _PAGE_COHERENT for all normal RAM pages thay have I = 0 on platforms that need it. The hash code clears it if the feature bit is not set. It also adds some clean accessors to setup various valid combinations of access flags and change various bits of code to use them instead. This should help having the PTE actually containing the bit combinations that we really want. I also removed _PAGE_GUARDED from _PAGE_BASE on 44x and instead set it explicitely from the TLB miss. I will ultimately remove it completely as it appears that it might not be needed after all but in the meantime, having it in the TLB miss makes things a lot easier.

2008-12-10fbcon: fix workqueue shutdownGeoff Levand
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. Fixes errors on shutdown similar to these: Console: switching to colour dummy device 80x25 Unable to handle kernel paging request for data at address 0x00000000 Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Cc: Krzysztof Helt <krzysztof.h1@poczta.fm> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
