From: "Kweh, Hock Leong" <hock.leong.kweh@xxxxxxxxx> Hi Guys, This patchset is created on top of "efi: Capsule update support" patch: http://permalink.gmane.org/gmane.linux.kernel.efi/4837 It leverages the request_firmware_nowait() to expose the user helper interface for user to upload the capsule binary and calling the efi_capsule_update() API to pass the binary to EFI firmware. Besides build in kernel, the design also cater for build as kernel driver module. This patchset introduce a new API (request_firmware_abort()) at firmware_class so that the driver module could be unloaded by calling the API to properly stop user helper interface and release the device. Thanks. --- changelog v2: [PATCH 1/3] * use fw_lookup_buf() instead of __fw_lookup_buf() function call * move the fw_lookup_buf() function out of the CONFIG_PM_SLEEP block [PATCH 2/3] * no change [PATCH 3/3] * no change Kweh, Hock Leong (3): firmware loader: Introduce new API - request_firmware_abort() firmware loader: fix hung task warning dump efi: Capsule update with user helper interface drivers/base/firmware_class.c | 56 ++++-- drivers/firmware/efi/Kconfig | 13 ++ drivers/firmware/efi/Makefile | 1 + drivers/firmware/efi/efi-capsule-user-helper.c | 246 ++++++++++++++++++++++++ include/linux/firmware.h | 4 + 5 files changed, 306 insertions(+), 14 deletions(-) create mode 100644 drivers/firmware/efi/efi-capsule-user-helper.c -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
