Ive left comments to patch 2/3 and 3/3 that still haven't been addressed: 2/3: We need to new UUID to be added to util.c like the rest of experimental UUIDs: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/src/shared/util.c#n1023 3/3: Instead of having a function that doesn't seem to be used anywhere it would probably be easier to enable whenever btd_opts.experimental is enable e.g.: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/src/adapter.c#n9293 > Thanks and best regards, > Joseph > > > On Tue, Jun 29, 2021 at 3:47 PM Joseph Hwang <josephsih@xxxxxxxxxxxx> wrote: > > > > This patch adds new Intel extended telemetry events for both ACL and > > SCO/eSCO audio link quality reports. > > > > For SCO/eSCO audio link quality report, it shows something like > > > HCI Event: Vendor (0xff) plen 190 #120 [hci0] 2021-05-31 20:27:50.257 > > Vendor Prefix (0x8780) > > Intel Extended Telemetry (0x87) > > Extended Telemetry (0x80): SubOpcode (0x03) > > Extended event type (0x01): Audio Link Quality Report Type(0x05) > > SCO/eSCO connection handle (0x6a): 0x0101 > > Packets from host (0x6b): 399 > > Tx packets (0x6c): 403 > > Rx payload lost (0x6d): 3 > > Tx payload lost (0x6e): 0 > > Rx No SYNC errors (0x6f): 3 2 3 3 0 > > Rx HEC errors (0x70): 0 0 0 0 0 > > Rx CRC errors (0x71): 2 0 0 0 0 > > Rx NAK errors (0x72): 6 0 0 0 0 > > Failed Tx due to Wifi coex (0x73): 6 0 0 0 0 > > Failed Rx due to Wifi coex (0x74): 0 0 0 0 0 > > Late samples inserted based on CDC (0x75): 0 > > Samples dropped (0x76): 0 > > Mute samples sent at initial connection (0x77): 0 > > PLC injection data (0x78): 0 > > > > For ACL audio link quality report, it shows something like > > > HCI Event: Vendor (0xff) plen 142 #120 [hci0] 2021-05-31 20:27:50.261 > > Vendor Prefix (0x8780) > > Intel Extended Telemetry (0x87) > > Extended Telemetry (0x80): SubOpcode (0x03) > > Extended event type (0x01): Audio Link Quality Report Type(0x05) > > ACL connection handle (0x4a): 0x0100 > > Rx HEC errors (0x4b): 0 > > Rx CRC errors (0x4c): 0 > > Packets from host (0x4d): 100 > > Tx packets (0x4e): 101 > > Tx packets 0 retries (0x4f): 89 > > Tx packets 1 retries (0x50): 11 > > Tx packets 2 retries (0x51): 1 > > Tx packets 3 retries (0x52): 0 > > Tx packets 4 retries and more (0x53): 0 > > Tx DH1 packets (0x54): 0 > > Tx DH3 packets (0x55): 0 > > Tx DH5 packets (0x56): 0 > > Tx 2DH1 packets (0x57): 0 > > Tx 2DH3 packets (0x58): 0 > > Tx 2DH5 packets (0x59): 0 > > Tx 3DH1 packets (0x5a): 6 > > Tx 3DH3 packets (0x5b): 0 > > Tx 3DH5 packets (0x5c): 94 > > Rx packets (0x5d): 272 > > ACL link throughput (KBps) (0x5e): 343815 > > ACL max packet latency (ms) (0x5f): 20625 > > ACL avg packet latency (ms) (0x60): 12 > > > > Reviewed-by: Miao-chen Chou <mcchou@xxxxxxxxxxxx> > > --- > > > > Changes in v5: > > - Fix two Make errors. > > - Please also review Series-changes 3. > > > > Changes in v4: > > - Fix a Make error. > > - Please also review Series-changes 3. > > > > Changes in v3: > > - Define the packed struct intel_ext_evt for the extended telemetry > > event. > > - Define the packed struct intel_tlv for the telemetry subevent. > > - Define a new function intel_vendor_prefix_evt() to handle the new > > vendor event type with a vendor prefix > > 0xff <length> <vendor_prefix> <subopcode> <data> > > while intel_vendor_evt() handles the original vendor event type > > 0xff <length> <subopcode> <data> > > - Add the vendor_prefix_evt_table table so that more subopcodes can be > > added for the events with a vendor prefix. > > - Move the event data buffer check after processing the current tlv. > > - Fix typos. > > > > Changes in v2: > > - Perform size checks for tlv subevents. > > - Fix the Make errors about qualifiers. > > > > monitor/intel.c | 492 ++++++++++++++++++++++++++++++++++++++++++++++- > > monitor/intel.h | 2 +- > > monitor/packet.c | 18 +- > > 3 files changed, 503 insertions(+), 9 deletions(-) > > > > diff --git a/monitor/intel.c b/monitor/intel.c > > index d2aefa6a8..7591df4ee 100644 > > --- a/monitor/intel.c > > +++ b/monitor/intel.c > > @@ -30,6 +30,7 @@ > > > > #define COLOR_UNKNOWN_EVENT_MASK COLOR_WHITE_BG > > #define COLOR_UNKNOWN_SCAN_STATUS COLOR_WHITE_BG > > +#define COLOR_UNKNOWN_EXT_EVENT COLOR_WHITE_BG > > > > static void print_status(uint8_t status) > > { > > @@ -992,14 +993,501 @@ static const struct vendor_evt vendor_evt_table[] = { > > { } > > }; > > > > -const struct vendor_evt *intel_vendor_evt(uint8_t evt) > > +/* > > + * An Intel telemetry subevent is of the TLV format. > > + * - Type: takes 1 byte.
