A DRM display driver for TI OMAP platform. Similar to omapfb (fbdev) and omap_vout (v4l2 display) drivers in the past, this driver uses the DSS2 driver to access the display hardware, including support for HDMI, DVI, and various types of LCD panels. And it implements GEM support for buffer allocation (for KMS as well as offscreen buffers used by the xf86-video-omap userspace xorg driver). The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's. Note that this arrangement might change slightly when support for drm_plane overlays is added. For GEM support, non-scanout buffers are using the shmem backed pages provided by GEM core (In drm_gem_object_init()). In the case of scanout buffers, which need to be physically contiguous, those are allocated with CMA and use drm_gem_private_object_init(). See userspace xorg driver: git://github.com/robclark/xf86-video-omap.git Refer to this link for CMA (Continuous Memory Allocator): http://lkml.org/lkml/2011/8/19/302 Links to previous versions of the patch: v1: http://lwn.net/Articles/458137/ v2: http://patches.linaro.org/4156/ v3: http://patches.linaro.org/4688/ v4: http://patches.linaro.org/4791/ History: v5: move headers from include/drm at Greg KH's request, minor rebasing on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages() because "drm/gem: add functions to get/put pages" patch is not merged yet v4: bit of rework of encoder/connector _dpms() code, modeset_init() rework to not use nested functions, update TODO.txt v3: minor cleanups, improved error handling for dev_load(), some minor API changes that will be needed later for tiled buffer support v2: replace omap_vram with CMA for scanout buffer allocation, remove unneeded functions, use dma_addr_t for physical addresses, error handling cleanup, refactor attach/detach pages into common drm functions, split non-userspace-facing API into omap_priv.h, remove plugin API v1: original Signed-off-by:

This patch implements a driver for the GE PIO2 VME Parallel I/O Card. This card is a 6U VME Card, implementing 32 solid-state relay switched IO lines, in 4 groups of 8. Each bank of IO lines is built to function as input, output or both depending on the variant of the card. Signed-off-by:

The functions vme_add_bus() and vme_remove_bus() were only being used in the vme_register_bridge() and vme_unregister_bridge() functions respectively. This patch gets rid of them and moves their code to vme_register_bridge() and vme_unregister_bridge(). Signed-off-by:

Use kzalloc rather than kmalloc followed by memset with 0 This considers some simple cases that are common and easy to validate Note in particular that there are no ...s in the rule, so all of the matched code has to be contiguous The semantic patch that makes this change is available in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.

rtllib_is_shortslot() takes one argument - a struct that's more than a kilobyte large. It should take a pointer instead of copying such a huge struct - and the argument might as well be declared 'const' now that we are at it, since it is not modified. This patch makes these changes. Signed-off-by:

This patch releases semaphore locks when an error occurrs while attempting to download firmware for the bcm driver. When downloading firmware for this driver, a process is expected to call the following ioctl's in this order: (1)IOCTL_BCM_BUFFER_DOWNLOAD_START, (2)IOCTL_BCM_BUFFER_DOWNLOAD, and (3) IOCTL_BCM_BUFFER_DOWNLOAD_STOP. Semaphore, “Adapter->fw_download_sema” is expected to be acquired in the first ioctl, IOCTL_BCM_BUFFER_DOWNLOAD_START, and it should block until IOCTL_BCM_BUFFER_DOWNLOAD_STOP is called. In this case, if an error occurred before STOP finished, the semaphore "Adapter->fw_download_sema" was not being released. Signed-off-by:

In this ioctl, we are testing to see if the lock is held. If it is not held, that means this ioctl used incorrectly. Therefore, we do not want to take the lock ourselves here. Signed-off-by:

This patch verifies two conditions before executing a kmalloc call. First, it checks to see that IoBuffer.OutputLength is not greater than an unsigned short. If so, an invalid value may be returned. The second change is a check to make sure IoBuffer.OutputLength is not equal to zero. Which simply keeps this code inline with the other ioctl, IOCTL_BCM_REGISTER_READ_PRIVATE. Signed-off-by:

Staging: bcm: Fix information leak in ioctl: IOCTL_BCM_REGISTER_READ_PRIVATE, IOCTL_BCM_EEPROM_REGISTER_READ This patch fixes an information leak in ioctl IOCTL_BCM_REGISTER_READ_PRIVATE and IOCTL_BCM_EEPROM_REGISTER_READ when determining the number of bytes to copy to user space. Function, usb_control_msg, returns the correct number of bytes from the hardware. Instead of using this value, we were using a value derived from user space. In this case, this value could be more than the hardware allocated. Therefore, this patch copies the proper number of bytes from the hardware, and uses this value as the maximum number of bytes for user space. Signed-off-by:
