| Series | Bluetooth: btmtk: add quirk to support HCI_QUIRK_SIMULTANEOUS_DISCOVERY | expand |
Dear Chris, Thank you for your patch. Am 13.12.24 um 10:41 schrieb Chris Lu: > Add quirk to support HCI_QUIRK_SIMULTANEOUS_DISCOVERY feature for MT79xx > series chipset. It’d be great if you elaborated. What is the problem. Why is a quirk needed? Is a firmware update going to fix it? > Signed-off-by: Chris Lu <chris.lu@mediatek.com> > --- > drivers/bluetooth/btmtk.c | 3 +++ > 1 file changed, 3 insertions(+) > > diff --git a/drivers/bluetooth/btmtk.c b/drivers/bluetooth/btmtk.c > index 8a3f7c3fcfec..562d6ecf0b71 100644 > --- a/drivers/bluetooth/btmtk.c > +++ b/drivers/bluetooth/btmtk.c > @@ -1367,6 +1367,9 @@ int btmtk_usb_setup(struct hci_dev *hdev) > return err; > } > > + /* Apply common HCI quirks for MediaTek chipset */ > + set_bit(HCI_QUIRK_SIMULTANEOUS_DISCOVERY, &hdev->quirks); > + The commit message only talks about MT79xx series chipset.

What is the problem. Why is a quirk > needed? Is a firmware update going to fix it? This quirk is related to do BR/EDR inquiry and LE scan simultaneously. More detailed was described in hci.h. Due to requirement from customer and other chip vendors also enable HCI_QUIRK_SIMULTANEOUS_DISCOVERY, MediaTek upload this patch to enable the feature as well. There is no need to update firmware. > > > Signed-off-by: Chris Lu <chris.lu@mediatek.com> > > --- > > drivers/bluetooth/btmtk.c | 3 +++ > > 1 file changed, 3 insertions(+) > > > > diff --git a/drivers/bluetooth/btmtk.c b/drivers/bluetooth/btmtk.c > > index 8a3f7c3fcfec..562d6ecf0b71 100644 > > --- a/drivers/bluetooth/btmtk.c > > +++ b/drivers/bluetooth/btmtk.c > > @@ -1367,6 +1367,9 @@ int btmtk_usb_setup(struct hci_dev *hdev) > > return err; > > } > > > > + /* Apply common HCI quirks for MediaTek chipset */ > > + set_bit(HCI_QUIRK_SIMULTANEOUS_DISCOVERY, &hdev- > > >quirks); > > + > > The commit message only talks about MT79xx series chipset.
