Please consider this version series ready for upstream acceptance. This patch series adds partial read support in request_firmware_into_buf. In order to accept the enhanced API it has been requested that kernel selftests and upstreamed driver utilize the API enhancement and so are included in this patch series. Also in this patch series is the addition of a new Broadcom VK driver utilizing the new request_firmware_into_buf enhanced API. Changes from v4: - handle reset issues if card crashes - allow driver to have min required msix - add card utilization information Changes from v3: - fix sparse warnings - fix printf format specifiers for size_t - fix 32-bit cross-compiling reports 32-bit shifts - use readl/writel,_relaxed to access pci ioremap memory, removed memory barriers and volatile keyword with such change - driver optimizations for interrupt/poll functionalities Changes from v2: - remove unnecessary code and mutex locks in lib/test_firmware.c - remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead - remove bitfields - remove Kconfig default m - adjust formatting and some naming based on feedback - fix error handling conditions - use appropriate return codes - use memcpy_toio instead of direct access to PCIE bar Scott Branden (7): fs: introduce kernel_pread_file* support firmware: add offset to request_firmware_into_buf test_firmware: add partial read support for request_firmware_into_buf firmware: test partial file reads of request_firmware_into_buf bcm-vk: add bcm_vk UAPI misc: bcm-vk: add Broadcom VK driver MAINTAINERS: bcm-vk: add maintainer for Broadcom VK Driver MAINTAINERS | 7 + drivers/base/firmware_loader/firmware.h | 5 + drivers/base/firmware_loader/main.c | 52 +- drivers/misc/Kconfig | 1 + drivers/misc/Makefile | 1 + drivers/misc/bcm-vk/Kconfig | 29 + drivers/misc/bcm-vk/Makefile | 12 + drivers/misc/bcm-vk/bcm_vk.h | 435 +++++ drivers/misc/bcm-vk/bcm_vk_dev.c | 1256 +++++++++++++++ drivers/misc/bcm-vk/bcm_vk_legacy.c | 89 + drivers/misc/bcm-vk/bcm_vk_msg.c | 1425 +++++++++++++++++ drivers/misc/bcm-vk/bcm_vk_msg.h | 196 +++ drivers/misc/bcm-vk/bcm_vk_sg.c | 271 ++++ drivers/misc/bcm-vk/bcm_vk_sg.h | 60 + drivers/misc/bcm-vk/bcm_vk_tty.c | 352 ++++ drivers/soc/qcom/mdt_loader.c | 7 +- fs/exec.c | 96 +- include/linux/firmware.h | 8 +- include/linux/fs.h | 20 + include/uapi/linux/misc/bcm_vk.h | 99 ++ lib/test_firmware.c | 144 +- .../selftests/firmware/fw_filesystem.sh | 80 + 22 files changed, 4596 insertions(+), 49 deletions(-) create mode 100644 drivers/misc/bcm-vk/Kconfig create mode 100644 drivers/misc/bcm-vk/Makefile create mode 100644 drivers/misc/bcm-vk/bcm_vk.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_dev.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_legacy.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_tty.c create mode 100644 include/uapi/linux/misc/bcm_vk.h -- 2.17.1
