Bluetooth: btusb: Only check needs_reset_resume DMI table for QCA rome chipsets

2018-05-16T08:12:34Z

commit fc54910280eb38bde923cdf0898e74687d8e6989 upstream. Jeremy Cline correctly points out in rhbz#1514836 that a device where the QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship with a different wifi/bt chipset in some configurations. If that is the case then we are needlessly penalizing those other chipsets with a reset-resume quirk, typically causing 0.4W extra power use because this disables runtime-pm. This commit moves the DMI table check to a btusb_check_needs_reset_resume() helper (so that we can easily also call it for other chipsets) and calls this new helper only for QCA_ROME chipsets for now.

Bluetooth: hci_bcm: Treat Interrupt ACPI resources as always being active-low

2018-04-19T06:54:12Z

commit bb5208b314c5127b716b2ee4f55803a8bb73b750 upstream. Older devices with a serdev attached bcm bt hci, use an Interrupt ACPI resource to describe the IRQ (rather then a GpioInt resource). These device seem to all claim the IRQ is active-high and seem to all need a DMI quirk to treat it as active-low. Instead simply always assume that Interrupt resource specified IRQs are always active-low. This fixes the bt device not being able to wake the host from runtime- suspend on the: Asus T100TAM, Asus T200TA, Lenovo Yoga2 and the Toshiba Encore, without the need to add 4 new DMI quirks for these models. This also allows us to remove 2 DMI quirks for the Asus T100TA and Asus T100CHI series. Likely the 2 remaining quirks can also be removed but I could not find a DSDT of these devices to verify this.

Bluetooth: hci_bcm: Set pulsed_host_wake flag in sleep parameters

2018-03-15T18:39:37Z

The IRQ output of the bcm bt-device is really a level IRQ signal, which signals a logical high as long as the device's buffer contains data. Since the draining in the buffer is done in the tty driver, we cannot (easily) wait in a threaded interrupt handler for the draining, after which the IRQ should go low again. So instead we treat the IRQ as an edge interrupt. This opens the window for a theoretical race where we wakeup, read some data and then autosuspend *before* the IRQ has gone (logical) low, followed by the device just at that moment receiving more data, causing the IRQ to stay high and we never see an edge. Since we call pm_runtime_mark_last_busy() on every received byte, there should be plenty time for the IRQ to go (logical) low before we ever suspend, so this should never happen, but after commit 43fff7683468 ("Bluetooth: hci_bcm: Streamline runtime PM code"), which has been reverted since, this was actually happening causing the device to get stuck in runtime suspend. The bcm bt-device actually has a workaround for this, if we set the pulsed_host_wake flag in the sleep parameters, then the device monitors if the host is draining the buffer and if not then after a timeout the device will pulse the IRQ line, causing us to see an edge, fixing the stuck in suspend condition. This commit sets the pulsed_host_wake flag to fix the (mostly theoretical) race caused by us treating the IRQ as an edge IRQ.
