udlfb has undergone a fair bit of cleanup recently and is effectively at the point where it can be liberated from staging purgatory and promoted to a real driver. The outstanding cleanups are all minor, with some of them dependent on drivers/video headers, so these will be done incrementally from udlfb's new home.

Some SH-Mobile SoCs have an HDMI controller and a PHY, attached to one of their LCDC interfaces. This patch adds a preliminary static support for such controllers, this means, that only the 720p mode is handled ATM. Support for more modes and a dynamic switching between them will be added by a follow up patch.

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.

This is the SuperH Mobile LCDC frame buffer driver V2, adding support for the LCDC block found in SuperH Mobile processors. The hardware supports up to two LCD panels per LCDC block, and both RGB and SYS interfaces can be used to hook up LCD panels/modules. The device driver is a regular platform driver, so LCD configuration and board specific hooks are passed to the driver using platform data. LCD modules using SYS interface often require special configuration using the SYS bus, and to solve this cleanly the driver provides SYS interface operations to the board code. Tested on sh7723 and sh7722 processors with a SYS16A QVGA panel and WVGA panels using RGB16 and RGB18 interfaces.

The following features are supported: plane 0 works as a regular frame buffer, can be accessed by /dev/fb0 plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2 plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4 Special ioctls support AOIs All /dev/fb* can be used as regular frame buffer devices, except hardware change can only be made through /dev/fb0. Changing pixel clock has no effect on other fbs. Limitation of usage of AOIs: AOIs on the same plane can not be horizonally overlapped AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1 AOIs can not beyond phisical display area. Application should check AOI geometry before changing physical resolution on /dev/fb0 required command line parameters to preallocate memory for frame buffer diufb. optional command line parameters to set modes and monitor video=fslfb:[resolution][,bpp][,monitor] Syntax: Resolution xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60 Bpp bpp=32, bpp=24, or bpp=16 Monitor monitor=0, monitor=1, monitor=2 0 is DVI 1 is Single link LVDS 2 is Double link LVDS Note: switching monitor is a board feather, not DIU feather.

The backends run in dom0 user space.

This patch adds Graphics Output Protocol support to the kernel. UEFI2.0 spec deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output Protocol (GOP) is produced. Therefore, the boot loader needs to query the UEFI firmware with appropriate Output Protocol and pass the video information to the kernel. As a result of GOP protocol, an EFI framebuffer driver is needed for displaying console messages. The patch adds a EFI framebuffer driver. The EFI frame buffer driver in this patch is based on the Intel Mac framebuffer driver. The ELILO bootloader takes care of passing the video information as appropriate for EFI firmware. The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI platform.

由 Michal Januszewski 提交于
uvesafb is an enhanced version of vesafb. It uses a userspace helper (v86d) to execute calls to the x86 Video BIOS functions. The driver is not limited to any specific arch and whether it works on a given arch or not depends on that arch being supported by the userspace daemon. It has been tested on x86_32 and x86_64. A single BIOS call is represented by an instance of the uvesafb_ktask structure. This structure contains a buffer, a completion struct and a uvesafb_task substructure, containing the values of the x86 registers, a flags field and a field indicating the length of the buffer. Whenever a BIOS call is made in the driver, uvesafb_exec() builds a message using the uvesafb_task substructure and the contents of the buffer. This message is then assigned a random ack number and sent to the userspace daemon using the connector interface. The message's sequence number is used as an index for the uvfb_tasks array, which provides a mapping from the messages coming from userspace to the in-kernel uvesafb_ktask structs. The userspace daemon performs the requested operation and sends a reply in the form of a uvesafb_task struct and, optionally, a buffer. The seq and ack numbers in the reply should be exactly the same as those in the request. Each message from userspace is processed by uvesafb_cn_callback() and after passing a few sanity checks leads to the completion of a BIOS call request.
