* fbdev: add mutex for fb_mmap lockingKrzysztof Helt2009-06-30
| | | | | | | | | | | | | | | | | | | | | Add a mutex to avoid a circular locking problem between the mm layer semaphore and fbdev ioctl mutex through the fb_mmap() call. Also, add mutex to all places where smem_start and smem_len fields change so the mutex inside the fb_mmap() is actually used. Changing of these fields before calling the framebuffer_register() are not mutexed. This is 2.6.31 material. It removes one lockdep (fb_mmap() and register_framebuffer()) but there is still another one (fb_release() and register_framebuffer()). It also cleans up handling of the smem_start and smem_len fields used by mutexed section of the fb_mmap().

| * [ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devicesEric Miao2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [ARM] pxafb: add support for FBIOPAN_DISPLAY by dma brachingEric Miao2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [ARM] pxafb: allow pxafb_set_par() to start from arbitrary yoffsetEric Miao2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [ARM] pxafb: allow video memory size to be configurableEric Miao2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.
