| * selftests/powerpc: Add script to test HMI functionalityDaniel Axtens2015-12-171-0/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HMIs (Hypervisor Management|Maintenance Interrupts) are a class of interrupt on POWER systems. HMI support has traditionally been exceptionally difficult to test, however Skiboot ships a tool that, with the correct magic numbers, will inject them. This, therefore, is a first pass at a script to inject HMIs and monitor Linux's response. It injects an HMI on each core on every chip in turn It then watches dmesg to see if it's acknowledged by Linux. On a Tuletta, I observed that we see 8 (or sometimes 9 or more) events per injection, regardless of SMT setting, so we wait for 8 before progressing. It sits in a new scripts/ directory in selftests/powerpc, because it's not designed to be run as part of the regular make selftests process. In particular, it is quite possibly going to end up garding lots of your CPUs, so it should only be run if you know how to undo that.

| * selftests/powerpc: Add test to check if VSRs are corruptedRashmica Gupta2015-12-143-1/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a transaction is aborted, VSR values should rollback to the checkpointed values before the transaction began. VSRs used elsewhere in the kernel during a transaction, or while the transaction is suspended should not affect the checkpointed values. Prior to the bug fix in commit d31626f70b61 ("powerpc: Don't corrupt transactional state when using FP/VMX in kernel") when VMX was requested by the kernel the .vr_state (which held the checkpointed state of VSRs before the transaction) was overwritten with the current state from outside the transation. Thus if the transaction did not complete, the VSR values would be "rolled back" to potentially incorrect values.

Add an explicit selftest. [ I wrote this while debugging a Bionic breakage -- my first guess was that I had somehow messed up sigreturn. I've caused problems in that code before, and it's really easy to fail to notice it because there's nothing on a modern distro that needs vdso-based sigreturn. ] Signed-off-by: Andy Lutomirski <luto@kernel.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.

On 32-bit builds, this works fine, but on 64-bit builds, it only works if the kernel has proper SS sigcontext handling for 64-bit user programs. Since the SS fixes are currently reverted, restrict the test case to 32 bits for now. In principle, I could change the test to use a different segment register, but it would be messy: CS can't point to the LDT for 64-bit code, and the other registers don't result in immediate faults because they aren't reloaded on kernel -> user transitions. When we fix sigcontext (in 4.6?), we can revert this.

Avoid this type of situation in the future and make list.h self-sufficient by copying the kernel list.h routines directly into tools list.h. This is a straight copy except for adjustments to the include statements and copying of the tools-specific list routines (list_del_range and list_for_each_from).

The 'for-4.5/block- dax' topic branch was rebased over the weekend to drop the "block device end-of-life" rework that Al would like to see re-implemented with a notifier, and to address bug reports against the badblocks integration. There is pending feedback against "libnvdimm: Add a poison list and export badblocks" received last week. Linda identified some localized fixups that we will handle incrementally. Summary: - Media error handling: The 'badblocks' implementation that originated in md-raid is up-levelled to a generic capability of a block device. This initial implementation is limited to being consulted in the pmem block-i/o path. Later, 'badblocks' will be consulted when creating dax mappings. - Raw block device dax: For virtualization and other cases that want large contiguous mappings of persistent memory, add the capability to dax-mmap a block device directly. - Increased /dev/mem restrictions: Add an option to treat all io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is actively using an address range. This behavior is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the existing "iomem=relaxed" kernel command line option. - Miscellaneous fixes include a 'pfn'-device huge page alignment fix, block device shutdown crash fix, and other small libnvdimm fixes" * tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (32 commits) block: kill disk_{check|set|clear|alloc}_badblocks libnvdimm, pmem: nvdimm_read_bytes() badblocks support pmem, dax: disable dax in the presence of bad blocks pmem: fail io-requests to known bad blocks libnvdimm: convert to statically allocated badblocks libnvdimm: don't fail init for full badblocks list block, badblocks: introduce devm_init_badblocks block: clarify badblocks lifetime badblocks: rename badblocks_free to badblocks_exit libnvdimm, pmem: move definition of nvdimm_namespace_add_poison to nd.h libnvdimm: Add a poison list and export badblocks nfit_test: Enable DSMs for all test NFITs md: convert to use the generic badblocks code block: Add badblock management for gendisks badblocks: Add core badblock management code block: fix del_gendisk() vs blkdev_ioctl crash block: enable dax for raw block devices block: introduce bdev_file_inode() restrict /dev/mem to idle io memory ranges arch: consolidate CONFIG_STRICT_DEVM in lib/Kconfig.debug ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The unit test infrastructure uses CMA and real memory to emulate nvdimm resources. The call to devm_memremap_pages() can simply be mocked in the same manner as memremap and we mock phys_to_pfn_t() to clear PFN_MAP since these resources are not registered with in the pgmap_radix.
