* OMAP: TILER: Optimize placement for NV12 buffersAndy Gross2014-10-012-16/+32
| | | | | | | | | | | | | | This patch changes the behaviour when allocating 2D buffers. If the required alignment is less than 4KiB and a security token is set, the allocation will be flagged specifically for this format. All subsequent buffers of the same format and size will be placed inside this area until the area is exhausted. For NV12 allocations, this means that all Y allocations will share one area, and the UV allocations will share another.

* TILER: Add tiler_backpages methodLajos Molnar2014-10-011-11/+50
| | | | | | | | | | | | tiler_backpages method can be used to get the number of pages required for a tiler allocation. This method is called before the memory is partitioned, therefore, we cannot rely on tiler being initialized. Separated geometry initialization for this purpose.

| * pvrusb2: fix 7MHz & 8MHz DVB-T tuner support for HVR1900 rev D1F5Michael Krufky2012-04-021-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 9ab2393fc3e460cd2040de1483918eb17abb822f upstream. The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner instead of a tda18271c1 tuner as used in revision D1E9. To account for this, we must hardcode the frontend configuration to use the same IF frequency configuration for both revisions of the device. 6MHz DVB-T is unaffected by this issue, as the recommended IF Frequency configuration for 6MHz DVB-T is the same on both c1 and c2 revisions of the tda18271 tuner.

| * uvcvideo: Fix integer overflow in uvc_ioctl_ctrl_map()Haogang Chen2012-01-252-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 806e23e95f94a27ee445022d724060b9b45cb64a upstream. There is a potential integer overflow in uvc_ioctl_ctrl_map(). When a large xmap->menu_count is passed from the userspace, the subsequent call to kmalloc() will allocate a buffer smaller than expected. map->menu_count and map->menu_info would later be used in a loop (e.g. in uvc_query_v4l2_ctrl), which leads to out-of-bound access. The patch checks the ioctl argument and returns -EINVAL for zero or too large values in xmap->menu_count.

Similar for another user's HVR-1270. Issues have also been reported with the HVR-1850 when MSI is enabled, and the 1850 behavior sounds similar to an as-yet-undiagnosed issue I've seen with an 1800.

| | * [media] msp3400: fill in v4l2_tuner based on vt->type fieldHans Verkuil2011-07-071-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | The vt->type field determines how the msp3400 should fill in the tuner data, not whether the msp3400 is in radio mode or not. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| | * [media] tuner-core.c: don't change type field in g_tuner or g_frequencyHans Verkuil2011-07-071-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tuner core should not silently change the type field in g_tuner and g_frequency. If the tuner is in a different mode than the one that was requested, then just fill in what you can and don't attempt to read afc, signal or rxsubchans values.

| | * [media] cx18/ivtv: fix g_tuner supportHans Verkuil2011-07-072-12/+4
| | | | | | | | | | | | | | | | | | | | | | | | The driver shouldn't override vt->type, and the tuner name should be based on vt->type as well. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| | * [media] tuner-core: power up tuner when called with s_power(1)Hans Verkuil2011-07-071-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers must be able to rely on s_power to power up subdevices. Note that at this moment no driver attempts to power up tuners. This probably isn't surprising since s_power(1) was never implemented in tuner-core.c until now.

| | * [media] v4l2-ioctl.c: check for valid tuner type in S_HW_FREQ_SEEKHans Verkuil2011-07-071-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | Prohibit attempts to change the tuner to a type that is different from the device node the ioctl is called from. I.e. the type must be RADIO for a radio node and ANALOG_TV for a video/vbi node. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| | * [media] tuner-core: simplify the standard fixupHans Verkuil2011-07-071-65/+28
| | | | | | | | | | | | | | | | | | | | | | | | Get rid of a number of unnecessary tuner_dbg messages by simplifying the std fixup function. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| | * [media] tuner-core/v4l2-subdev: document that the type field has to be filled inHans Verkuil2011-07-071-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tuner ops g_frequency, g_tuner and s_tuner require that the tuner type field is filled in. Document this. The tuner-core doc is based on a patch from Mauro Carvalho Chehab <mchehab@redhat.com>. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix typo: g_tuner should have been s_tuner. Tested with a bttv card. Cc: stable@kernel.org Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
