Hi Sean, >>>> this is even more hackish since the __hci_cmd_sync_ev command is really meant to get a cmd status first before waiting for that event. >>>> >>> >>> Understood. >>> >>> I've stopped the hack in v8. could we merge v8 first ? and then I will a fix up with __hci_raw_sync_ev that uses the hdev->raw_q instead of __hci_cmd_sync_ev in TODO. >> >> so I looked into this a bit more. We actually added __hci_cmd_send for a Qualcomm firmware loader that was doing something similar. So instead of trying to add a yet another command to the core, I actually used that and implemented the wait for vendor event in the driver. >> >> You will see my v9 on the mailing list. I also did a bunch of cosmetic minor cleanup and spelling correction. Please test this version. I also make __le16 dlen instead of dlen1 + dlen2 since I think that is what your hardware does. > > Only one thing needs to be corrected in v9. that is __be16 is required instead of dlen1 + dlen2. I will fix it up in v10 and the other changes all look good to me. > >> If this version of the driver works for you then I am happy to merge it. You can then add support for hdev->set_bdaddr and hdev->set_diag in later patches. I also like to clean up the STP receive handler since it can be done a lot simpler and smaller, but that has to wait. >> > > hopefully v10 also can be merged :) send me a v10 and I can merge it. > I will investigate more about how to add ->set_bdaddr, ->set_diag and STP receive enhancement in later patches. > > but so far I have not much idea about how to make STP multiplexer be a independent driver. > > my thought is that it would be really better and cleaner a chain of serdev is be used as the base of mtkbtuart. something like > > 8250 serial bus <----> STP multiplexer serdev <----> mtkbtuart serdev > > however, STP multiplexer serdev is not a real device, that doesn't no request any resource. I think it should not be allowed to be added in a device tree and even in dt-binding document. Before we do that, lets get a cleaner parser for it. I just don’t have enough time to wrap my head around this one yet. >>>> Are all Mediatek vendor commands this way? Or just the ones for loading the firmware? So only the WMT ones? >>>> >>> >>> Only the WMT ones, WMT commands/events are usually used in system controlling, for example, global function on/off, firmware download, reset and so on. most only appear on device initialization >> >> Since you never checked the result of the vendor event, I opted for just signaling that it arrived. If they can report success or failure, we need to add some extra code for that. >> > > I will consider more WMT event status when I add more Bluetooth devices such as MT7668U usb based Bluetooth which I plan to add the support in later patches in the next weeks Are the USB ones also using STP or are they H:2 based like all the others. What are prominent MT7668U based ones that I could buy?
