During firmware download, vendor specific events like boot up and secure send result are generated. These events can be safely processed at the driver level.

2024-11-14Bluetooth: btintel_pcie: Add handshake between driver and firmwareKiran K
The following handshake mechanism needs be followed after firmware download is completed to bring the firmware to running state. After firmware fragments of Operational image are downloaded and secure sends result of the image succeeds, 1. Driver sends HCI Intel reset with boot option #1 to switch FW image. 2. FW sends Alive GP[0] MSIx 3. Driver enables data path (doorbell 0x460 for RBDs, etc...) 4. Driver gets Bootup event from firmware 5. Driver performs D0 entry to device (WRITE to IPC_Sleep_Control =0x0) 6. FW sends Alive GP[0] MSIx 7. Device host interface is fully set for BT protocol stack operation. 8. Driver may optionally get debug event with ID 0x97 which can be dropped For Intermediate loadger image, all the above steps are applicable expcept #5 and #6. On HCI_OP_RESET, firmware raises alive interrupt. Driver needs to wait for it before passing control over to bluetooth stack.

2024-07-14Bluetooth: Add vendor-specific packet classification for ISO dataYing Hsu
When HCI raw sockets are opened, the Bluetooth kernel module doesn't track CIS/BIS connections. User-space applications have to identify ISO data by maintaining connection information and look up the mapping for each ACL data packet received. Besides, btsnoop log captured in kernel couldn't tell ISO data from ACL data in this case. To avoid additional lookups, this patch introduces vendor-specific packet classification for Intel BT controllers to distinguish ISO data packets from ACL data packets.

2023-02-09Bluetooth: btintel: Set Per Platform Antenna Gain(PPAG)Seema Sreemantha
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>

This patch fixes the broken LED quirk for Intel legacy ROM devices. To fix the LED issue that doesn't turn off immediately, the host sends the SW RFKILL command while shutting down the interface and it puts the devices in SW RFKILL state. Once the device is in SW RFKILL state, it can only accept HCI_Reset to exit from the SW RFKILL state. This patch checks the quirk for broken LED and sends the HCI_Reset before sending the HCI_Intel_Read_Version command.
