Bluetooth: btintel: Set Per Platform Antenna Gain(PPAG)
Antenna gain is defined as the antenna’s ability to increase the Tx power in a given direction. Intel is certifying its products with fixed reference antenna peak gain values (3/5dBi). The feature takes into account the actual antenna gain, and increases output power values, which results in a performance improvement. After firmware download is completed, driver reads from ACPI table and configures PPAG as required. ACPI table entry for PPAG is defined as below. Name (PPAG, Package (0x02) { 0x00000001, Package (0x02) { 0x00000012, /* Bluetooth Domain */ 0x00000001 /* 1 - Enable PPAG, 0 - Disable PPAG */ } }) btmon log: < HCI Command: Intel Configure Per Platform Antenna Gain (0x3f|0x0219) plen 12 Mcc: 0x00000000 Selector: Enable Delta: 0x00000000 > HCI Event: Command Complete (0x0e) plen 4 Intel Configure Per Platform Antenna Gain (0x3f|0x0219) ncmd 1 Status: Success (0x00) Signed-off-by: Kiran K <kiran.k@intel.com> Signed-off-by: Seema Sreemantha <seema.sreemantha@intel.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
