Currently vb2 core acquires mmap_sem just around call to __qbuf_userptr(). However since commit f035eb4e (videobuf2: fix lockdep warning) it isn't necessary to acquire it so early as we no longer have to drop queue mutex before acquiring mmap_sem. So push acquisition of mmap_sem down into .get_userptr and .put_userptr memops so that the semaphore is acquired for a shorter time and it is clearer what it is needed for. Signed-off-by:

This change will not change timing calculation. In CVT generator spreadsheet the nominal value of hsync (as a percentage of line) is 8 percent. Cc: Martin Bugge <marbugge@cisco.com> Signed-off-by:

Changed the rounding calculation for hblank and hsync to match it to equations in cvt and gtf standards. In cvt calculation, hsync needs to be rounded down. In gtf calculations, hblank needs to be rounded to nearest multiple of twice the cell granularity and hsync needs to be rounded to the nearest multiple of cell granularity.

Changed the rounding offsets used in vsync_bp calculation in cvt and gtf timings. The results for vsync_bp should now match with results from timing generator spreadsheets for cvt and gtf standards. In the vsync_bp calculation for cvt, always round down the value of (CVT_MIN_VSYNC_BP / h_period_est) and then add 1. It thus, reflects the equation used in timing generator spreadsheet. Using 1999999 as rounding offset, could pontentially lead to bumping up the vsync_bp value by extra 1. In the vsync_bp calculations for gtf, instead of round up or round down, round the (CVT_MIN_VSYNC_BP / h_period_est) to the nearest integer. Thanks to Martin Bugge <marbugge@cisco.com> for validating with standards and suggestions on equations. Cc: Martin Bugge <marbugge@cisco.com> Signed-off-by:

VIDEOBUF2_DMA_SG cannot be enabled manually by the user, it's always selected automatically by drivers that need it. Several of those drivers already have an explicit dependency on HAS_DMA. Make VIDEOBUF2_DMA_SG depend on HAS_DMA. This makes it easier to find drivers that select VIDEOBUF2_DMA_SG without depending on HAS_DMA, as Kconfig will give a warning. Signed-off-by: -

When using VIDIOC_G_EDID there is a special case where start_blocks and blocks are both set to 0. In that case the driver just has to set blocks to the total number of available blocks and return 0. Even though the drivers do this right and v4l2-compliance tests for it, it turned out not to be documented in the spec. Fix this. Signed-off-by:

If pci_disable_device() isn't called when the driver is removed, then the next time when it is loaded the irq isn't found. I'm pretty sure this used to work in the past, but calling pci_disable_device() is clearly the correct method and this makes it work again. Signed-off-by:

Fix three v4l2-compliance failures: - the colorspace wasn't set in vidioc_try_fmt_vid_cap(). - the field wasn't set in v4l2_buffer when vb2_buffer_done() was called. - the sequence wasn't set in v4l2_buffer when vb2_buffer_done() was called. This fix also removes the unused buf->count field and starts the count at 0 instead of 1. Signed-off-by:

The descriptions used in drivers for the formats returned with ENUM_FMT are all over the place. So instead allow the core to fill them in if the driver didn't. This allows drivers to drop the description and flags. Based on an earlier patch from Philipp Zabel: http://comments.gmane.org/gmane.linux.drivers.video-input-infrastructure/81411Signed-off-by:

They're not following what's specified at the DocBook: http://linuxtv.org/downloads/v4l-dvb-apis/vidioc-g-tuner.html#tuner-audmode Basically, it was assuming that the audmode (V4L2_TUNER_MODE_foo) is a variable with a bit maskk. However, it isn't. The bitmask only applies to rxsubchans field (V4L2_TUNER_SUB_foo). As the code is also too complex, and not all hooks were returning both audmode and rxsubchans to a VIDIOC_G_TUNER, rewrite the functions, in order to fix both for get and set tuner ioctls.
