* CEC: Add a new flag for set_optionJinsuk Kim2015-01-191-0/+9
| | | | | | | | | Added a flag to pass system language information to HAL so that it can respond to <Get Menu Language> in standby mode. Bug: 19054079 Change-Id: Iada00307202f5c9429944184b62b6456b624125a
* CEC: Add a parameter port ID to set_audio_return_channelJinsuk Kim2014-12-171-1/+1
| | | | | | | | | This CL addresses the cases where TV has more than one ARC-supported HDMI ports. Bug: 18781204 Change-Id: I4eaeb755caf2552b826a7322d19ee671407ee43f
* Revert "Update comment for send message."Jinsuk Kim2014-07-281-1/+1
| | | | | | | | This reverts commit 0e956a7cd2dee76b762320c141960ffdb64d24eb. The decision was to revert to the old behavior where retransmission will be handled by HAL for efficiency. Change-Id: If165b60c0408ea1015b83806f6bf21e18b15bc7f
* Update comment for send message.Jungshik Jang2014-07-211-1/+1
| | | | | | | HAL should not handle retransmission because it's handled by hdmi control service. Change-Id: I0daf1baf6f87805e2049ff84c6f8c2cace76dba2
* Use the term port_id for HDMI port index across definitionsJinsuk Kim2014-07-091-3/+4
| | | | | | | Renamed various terms like, port, port_num to port_id, and added a description that the id starts from 1. Change-Id: I9229edff7fd75dd15e672e309369e237ca339238
* Remove tx_status event in CEC HALJinsuk Kim2014-07-031-14/+3
| | | | | | | | | | Removes tx_status event type which turns out not in actual use. This changes makes send_message() work in sychrnonous fashion when called by HdmiControlService. HdmiControlService has io thread dedicated to interact with HAL, hence no need to introduce another async flow for HAL. Change-Id: I8ae21b1149cd36bfd0f9da215c4f23b30f0c8d30
* Update HDMI-CEC HAL interface for TVJinsuk Kim2014-05-201-22/+130
| | | | | | | | | | | | | | Added a few more API: - is_connected - get_port_info - set_option - set_audio_return_channel Also added another event type (tx_status) that reports the status of transmission. The status is reported in asynchronous fashion since the send operation can take longer due to bus conflict. Change-Id: I75decb8451a23f8a8eda0895d58f22c45227c0b3
* Add ARC commandsJungshik Jang2014-05-161-1/+7
| | | | | | | | | | | | | | | | ARC, Audio Return Channel is newly introduced in HDMI CEC 1.4. Here is a list of new command <Initiate ARC> <Report ARC Initiated> <Report ARC Terminated> <Request ARC Initiation> <Request ARC Termination> <Terminate ARC> Along with it replaced <Get OSD Name> with <Give OSD Name> which is renamed in CEC 1.4. Change-Id: I6a03b30cf90a8f6dca54831355be05682a6df96c
* Described restrictions for common HAL object methods.Stewart Miles2014-05-121-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inheritance of HAL object is performed by composing a child structure of a single parent structure located at offset 0 followed by new data members and function pointers in the child structure. For example, struct child { struct parent common; int a_data_member; void (*a_method)(struct child *c, int v); }; HAL code assumes this layout when accessing child structures given a pointer to a parent structure such that users write code like the following... void child_method(struct *parent, int v) { struct child * c = (struct child*)parent; // do stuff with c } Code above will break if a member is added before "common" in "struct child". This change adds comments that describe the restriction on the location of parent HAL objects within a derived HAL object. HAL objects that already have comments that describe the required location of parent objects are not modified. Change-Id: Ibe4300275286ef275b2097534c84f1029d761d87
* Update HDMI-CEC HAL interface definitionJinsuk Kim2014-04-131-25/+17
| | | | | | | | | | | | | | | | | | | | Previously it was HAL that was responsible for the logical address allocation. The address allocation logic itself is based on the algorithm specified in the CEC standard, is dependent neither on vendor nor on hardware. This CL replaces the method 'allocate_logical_address', 'get_logical_address' with 'add_logical_address', so that the common allocation logic will be implemented in the cec service and can be used by all vendors without having them put the same logic in all HAL implementations. HAL is supposed to be passed the allocated address and use it to configure the chipset in this new definition. The change in the service that implements the address allocation logic will be done in a follow up CL. Also removed the description in 'get_version' about version number. It needs not be in the description since it is an implementation detail. Change-Id: I33f31580792785bec38b7bd6997f91b89bfbb500
* Added message_abort and operand enumsJinsuk Kim2014-03-241-7/+22
| | | | | | | Also clarfieid the method description (allocate_logical_address), update method signatures to use more appropriate type. Change-Id: Ie5d13969308e77ca19b3dbde682ca968337ab41b
* Add 'get_logical_address' in HDMI-CEC HAL interfaceJinsuk Kim2014-03-111-1/+16
| | | | | | | The new function allows the HDMI-CEC service to get the logical address updated by HAL implementation. Change-Id: I1a4c5f7b7773279091d5bd7c6971a8c9090a81ca
* [HDMI-CEC] Modify the signature of register_event_callbackJinsuk Kim2014-03-081-4/+6
| | | | | | | Additional parameter helps the caller avoid managing a static instance variable. The parameter is used to pass the caller object itself. Change-Id: I06cbcc7736031678f4638a0b5082d7b6a7ea51b6
* Header file for HDMI-CEC HAL interface definitionJinsuk Kim2014-02-201-0/+282
Added here is the header file that defines HDMI-CEC HAL interface. Its main purpose is to support major CEC features such as 'one touch play', 'standby' for playback device. But basic skeleton for supporting other kinds of devices(like TV) is also in place. Change-Id: Iccbbec398bc675d69cb78ad6848ec57ac727cb8d
