Add and use a helper function to set actual buffer size for particular buffer type. This is also preparation to use the second decoder output. Signed-off-by:
-
Stanimir Varbanov authored
Adds a new helper function to set dynamic buffer mode if it is supported by current HFI version. The dynamic buffer mode is set unconditionally for both decoder outputs. Signed-off-by:

Rename is_reg_unreg_needed() to better name is_dynamic_bufmode() and use buffer mode from enumerated per codec capabilities. Signed-off-by:
-
Stanimir Varbanov authored
This adds common capability parser for all supported Venus versions. Having it will help to enumerate better the supported raw formats and codecs and also the capabilities for every codec like max/min width/height, framerate, bitrate and so on. Signed-off-by:

Add two more clocks for Venus 4xx in core structure and create a new power enable function to handle it for 3xx/4xx versions. Signed-off-by:
-
Stanimir Varbanov authored
This adds suspend (power collapse) functionality by reusing the suspend function for Venus 3xx and also enables idle indicator property for Venus 4xx (where it is disabled by default). Signed-off-by:
-
Stanimir Varbanov authored
This moves setting of default properties (firmware debug, idle indicator and low power mode) from session init to core init. All of those properties are need to be enabled/disabled early so that they could be used before the clients are even initialized. The other reason is to set idle indicator property early before we enter into venus_suspend function where we need to check for ARM9 WFI. Signed-off-by:
-
Stanimir Varbanov authored
This fixes the suspend function for Venus 3xx versions by add a check for WFI (wait for interrupt) bit. This bit is on when the ARM9 is idle and entered in low power mode. Signed-off-by:

Add AXI halt support for version 4xx by using venus wrapper registers. Signed-off-by:

Stanimir Varbanov authored
This adds handling of buffers of type OUTPUT2 which is needed to support Venus 4xx version. Signed-off-by:

Stanimir Varbanov authored
This makes possible to handle session_continue for 4xx as well. Signed-off-by:
-
Stanimir Varbanov authored
Adds set_properties method to handle newer 4xx properties and fall-back to 3xx for the rest. Signed-off-by:

HFI version 4xx can pass more properties in the sequence change event, extend the event structure with them. Signed-off-by:

Comparing an int to a size, which is unsigned, causes the int to become unsigned, giving the wrong result. kinect_read returns the result of usb_control_msg, which can return a negtive error code. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ int x; expression e,e1; identifier f; @@ *x = f(...); ... when != x = e1 when != if (x < 0 || ...) { ... return ...; } *x < sizeof(e) // </smpl> Signed-off-by:

The error path currently calls tw686x_video_free() which requires vc->dev to be initialized, causing a NULL dereference on uninitizalized channels. Fix this by setting the vc->dev fields for all the channels first. Fixes: f8afaa8d ("[media] tw686x: Introduce an interface to support multiple DMA modes") Signed-off-by:

Hans Verkuil authored
The use of 'DTV' is very confusing since it normally refers to Digital TV e.g. DVB etc. Instead use 'DV' (Digital Video), which nicely corresponds to the DV Timings API used to configure such receivers and transmitters. We keep an alias to avoid breaking userspace applications. Since this alias is only available if __KERNEL__ is *not* defined (i.e. it is only available for userspace, not kernelspace), any drivers that use it also have to be converted to the new define. These drivers are adv7604, adv7842 and tda1997x. Signed-off-by:

The v2 entity structure never exposed the entity flags, which made it impossible to detect connector or default entities. It is really trivial to just expose this information, so implement this. Signed-off-by:
