Bluetooth: btrtl: Use kvmalloc for FW allocations

2020-01-24T18:57:53Z

Currently, kmemdup is applied to the firmware data, and it invokes kmalloc under the hood. The firmware size and patch_length are big (more than PAGE_SIZE), and on some low-end systems (like ASUS E202SA) kmalloc may fail to allocate a contiguous chunk under high memory usage and fragmentation: Bluetooth: hci0: RTL: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8821 Bluetooth: hci0: RTL: rom_version status=0 version=1 Bluetooth: hci0: RTL: loading rtl_bt/rtl8821a_fw.bin kworker/u9:2: page allocation failure: order:4, mode:0x40cc0(GFP_KERNEL|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0 As firmware load happens on each resume, Bluetooth will stop working after several iterations, when the kernel fails to allocate an order-4 page. This patch replaces kmemdup with kvmalloc+memcpy. It's not required to have a contiguous chunk here, because it's not mapped to the device directly.

Bluetooth: hci_qca: Enable power off/on support during hci down/up for QCA Rome

2020-01-16T05:30:35Z

This patch registers hdev->shutdown() callback and also sets HCI_QUIRK_NON_PERSISTENT_SETUP for QCA Rome. It will power-off the BT chip during hci down and power-on/initialize the chip again during hci up. As wcn399x already enabled this, this patch also removed the callback register and QUIRK setting in qca_setup() for wcn399x and uniformly do this in the probe() routine.

Bluetooth: hci_qca: Retry btsoc initialize when it fails

2020-01-15T21:36:57Z

This patch adds the retry of btsoc initialization when it fails. There are reports that the btsoc initialization may fail on some platforms but the repro ratio is very low. The symptoms is the firmware downloading failed due to the UART write timed out. The failure may be caused by UART, platform HW or the btsoc itself but it's very difficlut to root cause, given the repro ratio is very low. Add a retry for the btsoc initialization can work around most of the failures and make Bluetooth finally works.

Bluetooth: hci_qca: Add QCA Rome power off support to the qca_power_shutdown()

2020-01-15T21:36:57Z

Current qca_power_shutdown() only supports wcn399x, this patch adds Rome power off support to it. For Rome it just needs to pull down the bt_en GPIO to power off it. This patch also replaces all the power off operation in qca_close() with the unified qca_power_shutdown() call.

Bluetooth: hci_bcm: enable IRQ capability from devicetree

2020-01-15T21:32:31Z

Add support for getting IRQ directly from DT instead of relying on converting a GPIO to IRQ. This is needed for platforms with GPIO controllers that that do not support gpiod_to_irq(). Reviewed-by: Kevin Hilman Signed-off-by: Guillaume La Roque Signed-off-by: Marcel Holtmann

Bluetooth: hci_qca: Add qca_power_on() API to support both wcn399x and Rome power up

2020-01-14T13:54:03Z

This patch adds a unified API qca_power_on() to support both wcn399x and Rome power on. For wcn399x it calls the qca_wcn3990_init() to init the regulators, and for Rome it pulls up the bt_en GPIO to power up the btsoc. It also moves all the power up operation from hdev->open() to hdev->setup(). Signed-off-by: Rocky Liao Reviewed-by: Matthias Kaehlcke Signed-off-by: Marcel Holtmann
