Cache boot_addr in struct btintel_data for the replay. No functional change on its own. Signed-off-by: Chandrashekar Devegowda --- Changes in v2: - Drop btintel_top_reset_pending() and the operational image special case; check INTEL_TOP_RESET directly in btintel_boot(). - Clear the cached boot_addr when reading the firmware version. v1: https://lore.kernel.org/linux-bluetooth/20261014114752.174669-1-chandrashekar.devegowda@intel.com/ drivers/bluetooth/btintel.c | 23 +++++++++++++++++++++++ drivers/bluetooth/btintel.h | 2 ++ 2 files changed, 25 insertions(+) diff --git a/drivers/bluetooth/btintel.c b/drivers/bluetooth/btintel.c index 0709fb3212f9..999b292bb69e 100644 --- a/drivers/bluetooth/btintel.c +++ b/drivers/bluetooth/btintel.c @@ -1238,6 +1238,12 @@ static bool btintel_firmware_version(struct hci_dev *hdev, { const u8 *fw_ptr; + if (hdev->bus == HCI_PCI) { + struct btintel_data *data = hci_get_priv(hdev); + + data->boot_addr = 0; + } + fw_ptr = fw->data; while (fw_ptr - fw->data < fw->size) { @@ -1255,6 +1261,12 @@ static bool btintel_firmware_version(struct hci_dev *hdev, *boot_addr = le32_to_cpu(params->boot_addr); + if (hdev->bus == HCI_PCI) { + struct btintel_data *data = hci_get_priv(hdev); + + data->boot_addr = *boot_addr; + } + bt_dev_info(hdev, "Boot Address: 0x%x", *boot_addr); bt_dev_info(hdev, "Firmware Version: %u-%u.%u", @@ -2064,6 +2076,13 @@ static int btintel_boot(struct hci_dev *hdev, u32 boot_addr) ktime_t calltime; int err; + /* Let the transport replace the Intel soft reset for a TOP reset */ + if (hdev->bus == HCI_PCI && + btintel_test_flag(hdev, INTEL_TOP_RESET)) { + bt_dev_info(hdev, "TOP reset pending, skipping Intel soft reset"); + return -ECANCELED; + } + calltime = ktime_get(); btintel_set_flag(hdev, INTEL_BOOTING); @@ -3549,6 +3568,7 @@ int btintel_bootloader_setup_tlv(struct hci_dev *hdev, struct intel_version_tlv new_ver; struct btintel_data *data = hci_get_priv(hdev); u8 hw_variant = INTEL_HW_VARIANT(ver->cnvi_bt); + bool top_reset = btintel_test_flag(hdev, INTEL_TOP_RESET); bt_dev_dbg(hdev, ""); @@ -3565,6 +3585,9 @@ int btintel_bootloader_setup_tlv(struct hci_dev *hdev, for (int i = 0; i < __INTEL_NUM_FLAGS; i++) btintel_clear_flag(hdev, i); + if (top_reset) + btintel_set_flag(hdev, INTEL_TOP_RESET); + btintel_set_flag(hdev, INTEL_BOOTLOADER); data->unlocker = false; diff --git a/drivers/bluetooth/btintel.h b/drivers/bluetooth/btintel.h index 9526acf65959..97fbe0ddf2d3 100644 --- a/drivers/bluetooth/btintel.h +++ b/drivers/bluetooth/btintel.h @@ -257,6 +257,7 @@ enum { INTEL_ROM_LEGACY_NO_WBS_SUPPORT, INTEL_ACPI_RESET_ACTIVE, INTEL_WAIT_FOR_D0, + INTEL_TOP_RESET, __INTEL_NUM_FLAGS, }; @@ -265,6 +266,7 @@ struct btintel_data { DECLARE_BITMAP(flags, __INTEL_NUM_FLAGS); int (*acpi_reset_method)(struct hci_dev *hdev); u32 cnvi_bt; + u32 boot_addr; bool unlocker; }; base-commit: 27731ba091954eccddb2657053b590d2113e8d98 -- 2.43.0
