Add a generic file io (read and write) emulator for videobuf2. It uses MMAP memory type buffers and generic vb2 calls: req_bufs, qbuf and dqbuf. Video date is being copied from mmap buffers to userspace with standard copy_to_user() function. To add support for file io the driver needs to provide an additional callback - read_setup or write_setup. It should provide the default number of buffers used by emulator and flags. With these flags one can detemine the style of read() or write() emulation. By default 'streaming' style is used. With VB2_FILEIO_READ_ONCE flag one can select 'one shot' mode for read() emulator. With VB2_FILEIO_WRITE_IMMEDIATE flag one can select immediate conversion of write calls to qbuf for write() emulator, so the vb2 will not wait until each buffer is filled completely before queueing it to the driver.

Videobuf2 is a Video for Linux 2 API-compatible driver framework for multimedia devices. It acts as an intermediate layer between userspace applications and device drivers. It also provides low-level, modular memory management functions for drivers. Videobuf2 eases driver development, reduces drivers' code size and aids in proper and consistent implementation of V4L2 API in drivers. Videobuf2 memory management backend is fully modular. This allows custom memory management routines for devices and platforms with non-standard memory management requirements to be plugged in, without changing the high-level buffer management functions and API. The framework provides: - implementations of streaming I/O V4L2 ioctls and file operations - high-level video buffer, video queue and state management functions - video buffer memory allocation and management Signed-off-by: NPawel Osciak <p.osciak@samsung.com> Signed-off-by: NMarek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com> CC: Pawel Osciak <pawel@osciak.com> Reviewed-by: NHans Verkuil <hverkuil@xs4all.nl> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

由 Pawel Osciak 提交于
Multi-planar API is as a backwards-compatible extension of the V4L2 API, which allows video buffers to consist of one or more planes. Planes are separate memory buffers; each has its own mapping, backed by usually separate physical memory buffers. Many different uses for the multi-planar API are possible, examples include: - embedded devices requiring video components to be placed in physically separate buffers, e.g. for Samsung S3C/S5P SoC series' video codec, Y and interleaved Cb/Cr components reside in buffers in different memory banks; - applications may receive (or choose to store) video data of one video buffer in separate memory buffers; such data would have to be temporarily copied together into one buffer before passing it to a V4L2 device; - applications or drivers may want to pass metadata related to a buffer and it may not be possible to place it in the same buffer, together with video data.

This patch is adding support for Technisat's new USB2.0 DVB-S/S2 receiver device. The development was sponsored by Technisat. The Green led is toggle depending on the frontend-state. The Red LED is turned on all the time. The MAC address reading from the EEPROM along with the LRC-method to check whether its valid. Support for the IR-receiver of the Technisat USB2 box. The keys of small, black remote-control are built-in, repeated key behaviour are simulated. The i2c-mutex of the dvb-usb-structure is used as a general mutex for USB requests, as there are 3 threads racing for atomic requests consisting of multiple usb-requests. A module option is there which disables the toggling of LEDs by the driver on certain triggers. Useful when being used in a "dark" environment.

hpwdt_init_nmi_decoding() is called in hpwdt_init_one error handling, thus remove the __devexit annotation of hpwdt_exit_nmi_decoding(). This patch fixes below warning: WARNING: drivers/watchdog/hpwdt.o(.devinit.text+0x36f): Section mismatch in reference from the function hpwdt_init_one() to the function .devexit.text:hpwdt_exit_nmi_decoding() The function __devinit hpwdt_init_one() references a function __devexit hpwdt_exit_nmi_decoding(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of hpwdt_exit_nmi_decoding() so it may be used outside an exit section.

So we used to use lpfn directly to restrict VRAM when we couldn't access the unmappable area, however this was removed in 93225b0d as it also restricted the gtt placements. However it was only later noticed that this broke on some hw. This removes the active_vram_size, and just explicitly sets it when it changes, TTM/drm_mm will always use the real_vram_size, and the active vram size will change the TTM size used for lpfn setting. We should re-work the fpfn/lpfn to per-placement at some point I suspect, but that is too late for this kernel. Hopefully this addresses: https://bugs.freedesktop.org/show_bug.cgi?id=35254 v2: fix reported useful VRAM size to userspace to be correct. Signed-off-by: NDave Airlie <airlied@redhat.com>
