[PATCH bpf-next] selftests/bpf: add general instructions for test execution

by Alan Maguire

Getting a clean BPF selftests run involves ensuring latest trunk LLVM/clang are used, pahole is recent (>=1.16) and config matches the specified config file as closely as possible. Document all of this in the general README.rst file. Also note how to work around timeout failures.

[PATCH v2] selftests: introduce gen_tar Makefile target

by Veronika Kabatova

The gen_kselftest_tar.sh always packages *all* selftests and doesn't pass along any variables to `make install` to influence what should be built. This can result in an early error on the command line ("Unknown tarball format TARGETS=XXX"), or unexpected test failures as the tarball contains tests people wanted to skip on purpose. Since the makefile already contains all the logic, we can add a target for packaging. Keep the default .gz target the script uses, and actually extend the supported formats by using tar's autodetection. To not break current workflows, keep the gen_kselftest_tar.sh script as it is, with an added suggestion to use the makefile target instead.

[PATCH v2] mm/hmm/test: use xa_for_each_range instead of looping

by Ralph Campbell

The test driver uses an xa_array to store virtual to physical address translations for a simulated hardware device. The MMU notifier invalidation callback is used to keep the table consistent with the CPU page table and is frequently called only for a page or two. However, if the test process exits unexpectedly or is killed, the range can be [0..ULONG_MAX] in which case calling xa_erase() for every possible PFN results in CPU timeouts. Use xa_for_each_range() to efficiently erase entries in the range.

[PATCH 0/2] selftests/vm: minor fixes for 5.7-rc5

by John Hubbard

Here's a couple of tiny fixes, just so we can cleanly build selftests/vm. These apply to today's linux.git. Some merge notes: * The .gitignore fix is appropriate for linux.git, but it is a subset of what's required for linux-next and mmotm. In order to fix things now in linux.git, and keep it fixed in mmotm and linux-next, but without manual intervention required in git merges, I'm adding the missing item ("mremap_dontunmap") to the *top* of .gitignore for this patch. And then I'll send a separate patch to be applied to mmotm and linux-next, that will also add a different item ("khugepaged") to the *bottom* of .gitignore. * The write_to_hugetlbfs.c fix is already applied to linux-next, but doesn't seem to be getting picked up for linux.git. Maybe it's in the merge pipeline, but if not, let's fix it here, before the -rc cycle is over.

[PATCH v5 0/7] firmware: add partial read support in request_firmware_into_buf

by Scott Branden

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
