      lib: Move fonts from drivers/video/console/ to lib/fonts/ · ee89bd6b
      Geert Uytterhoeven 提交于
      Several drivers need font support independent of CONFIG_VT, cfr. commit
      9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font
      support code selection logic").
      Hence move the fonts and their support logic from drivers/video/console/ to
      its own library directory lib/fonts/.
      This also allows to limit processing of drivers/video/console/Makefile to
      CONFIG_VT=y again.

      console/font: Refactor font support code selection logic · d1e183c8
      Geert Uytterhoeven 提交于
      The current Makefile rules to build font support are messy and buggy.
      Replace them by Kconfig rules:
        - Introduce CONFIG_FONT_SUPPORT, which controls the building of all font
          code,
        - Select CONFIG_FONT_SUPPORT for all drivers that use fonts,
        - Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16
          font,
        - Drop the bogus console dependency for CONFIG_VIDEO_VIVI,
        - Always process drivers/video/console/Makefile, as some drivers need
          fonts even if CONFIG_VT is not set.
      
      This fixes (if CONFIG_SOLO6X10=y and there are no built-in console
      drivers):
      
      drivers/built-in.o: In function `solo_osd_print':
      drivers/staging/media/solo6x10/solo6x10-enc.c:144: undefined reference to `.find_font'
      
      This fixes (if CONFIG_VT=n):

      vivi.c:(.init.text+0x1a3da): undefined reference to `find_font'

      drivers/video: implement a simple framebuffer driver · 26549c8d
      Stephen Warren 提交于
      A simple frame-buffer describes a raw memory region that may be rendered
      to, with the assumption that the display hardware has already been set
      up to scan out from that buffer.
      
      This is useful in cases where a bootloader exists and has set up the
      display hardware, but a Linux driver doesn't yet exist for the display
      hardware.
      
      Examples use-cases include:
      
      * The built-in LCD panels on the Samsung ARM chromebook, and Tegra
        devices, and likely many other ARM or embedded systems.  These cannot
        yet be supported using a full graphics driver, since the panel control
        should be provided by the CDF (Common Display Framework), which has been
        stuck in design/review for quite some time.  One could support these
        panels using custom SoC-specific code, but there is a desire to use
        common infra-structure rather than having each SoC vendor invent their
        own code, hence the desire to wait for CDF.
      
      * Hardware for which a full graphics driver is not yet available, and
        the path to obtain one upstream isn't yet clear.  For example, the
        Raspberry Pi.
      
      * Any hardware in early stages of upstreaming, before a full graphics
        driver has been tackled.  This driver can provide a graphical boot
        console (even full X support) much earlier in the upstreaming process,
        thus making new SoC or board support more generally useful earlier.

      videomode: simplify videomode Kconfig and Makefile · a38884f6
      Tomi Valkeinen 提交于
      This patch simplifies videomode related Kconfig and Makefile. After this
      patch, there's only one non-user selectable Kconfig option left,
      VIDEOMODE_HELPERS. The reasons for the change:
      
      * Videomode helper functions are not something that should be shown in
        the kernel configuration options. The related code should just be
        included if it's needed, i.e. selected by drivers using videomode.
      
      * There's no need to have separate Kconfig options for videomode and
        display_timing. First of all, the amount of code for both is quite
        small. Second, videomode depends on display_timing, and display_timing
        in itself is not really useful, so both would be included in any case.
      
      * CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS
        describes better what's included.

      changes since v2:
      
      - use v3 and v4 for specifying the ip version instead of i.MX23/28.
        This is a better namespace when future versions are added.
      - rename mach/fb.h to mach/mxsfb.h
      
      changes since v1:
      - Add a LCDC_ prefix to the register names.
      - use set/clear registers where appropriate
      - protect call to mxsfb_disable_controller() in mxsfb_remove()

      video: add driver for PXA3xx 2D graphics accelerator · 364dbdf3
      Daniel Mack 提交于
      This adds a driver for the the 2D graphics accelerator found on PXA3xx
      processors. Only resource mapping, interrupt handling and a simple ioctl
      handler is done by the kernel part, the rest of the logic is implemented
      in DirectFB userspace.
      
      Graphic applications greatly benefit for line drawing, blend, and
      rectangle and triangle filling operations.
      
      Benchmarks done on a PXA303 using the df_dok benchmarking tool follow,
      where the value in square brackets show the CPU usage during that test.
      
      Without accelerator (benchmarking 256x252 on 480x262 RGB16 (16bit)):

      OMAP: Add VRAM manager · afedec18
      Tomi Valkeinen 提交于
      Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used
      to allocate large continuous blocks of SDRAM or SRAM. The features VRAM
      manager has that are missing from dma_alloc_* functions are:
      
      - Support for OMAP2's SRAM
      - Allocate without ioremapping
      - Allocate at defined physical addresses
      - Allows larger VRAM area and larger allocations
      
      The upcoming DSS2 uses VRAM manager.
      
      VRAM area size can be defined in kernel config, board file or with
      kernel boot parameters. Board file definition overrides kernel config,
      and boot parameter overrides kernel config and board file.
