2020-07-27mtd: spi-nor: micron: Add SPI_NOR_DUAL_READ flag on mt25qu02gDavid Clear
The Micron mt25qu02g supports both x2 and x4 transactions. Add the SPI_NOR_DUAL_READ flag to its spi_nor_ids[] table entry. Tested on Pensando SoC hardware with a cadence quadspi controller via drivers/spi/spi-cadence-quadspi.c, in x2 mode at 50MHz. - random data write, erase, read - verified erase operations - random data write, read/compare - verified write/read operations Signed-off-by: David Clear <dac2@pensando.io> Acked-by: Shannon Nelson <snelson@pensando.io> Link: https://lore.kernel.org/r/20200720163656.38006-3-dac2@pensando.io Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com>

2020-07-27mtd: spi-nor: intel-spi: Simulate WRDI commandAlexander Sverdlin
After spi_nor_write_disable() return code checks were introduced in the spi-nor front end intel-spi backend stopped to work because WRDI was never supported and always failed. Just pretend it was sucessful and ignore the command itself. HW sequencer shall do the right thing automatically, while with SW sequencer we cannot do it anyway, because the only tool we had was preopcode and it makes no sense for WRDI.

Double Transfer Rate (DTR) ops are added in spi-mem. But this controller doesn't support DTR transactions.

2020-07-14spi: spi-mem: allow specifying a command's extensionPratyush Yadav
In xSPI mode, flashes expect 2-byte opcodes. The second byte is called the "command extension". There can be 3 types of extensions in xSPI: repeat, invert, and hex. When the extension type is "repeat", the same opcode is sent twice. When it is "invert", the second byte is the inverse of the opcode. When it is "hex" an additional opcode byte based is sent with the command whose value can be anything. So, make opcode a 16-bit value and add a 'nbytes', similar to how multiple address widths are handled. Some places use sizeof(op->cmd.opcode). Replace them with op->cmd.nbytes The spi-mxic and spi-zynq-qspi drivers directly use op->cmd.opcode as a buffer. Now that opcode is a 2-byte field, this can result in different behaviour depending on if the machine is little endian or big endian. Extract the opcode in a local 1-byte variable and use that as the buffer instead. Both these drivers would reject multi-byte opcodes in their supports_op() hook anyway, so we only need to worry about single-byte opcodes for now. The above two changes are put in this commit to keep the series bisectable.

2020-07-13mtd: spi-nor: Disable the flash quad mode in spi_nor_restore()Yicong Yang
If the flash's quad mode is enabled, it'll remain in the quad mode when it's removed. If we drive the flash next time in Standard/Dual SPI mode, the QE bit is not cleared and the function of flash's WP# and RESET#/HOLD# have been switched to IO2 and IO3 and are not restored. Disable the Quad mode in spi_nor_restore(), then the flash's QE bit will be cleared when removed. This will make sure the flash always enter the Standard/Dual SPI mode when loaded.

2020-07-13mtd: spi-nor: sfdp: do not make invalid quad enable fatalPratyush Yadav
The Micron MT35XU512ABA flash does not support the quad enable bit. But instead of programming the Quad Enable Require field to 000b ("Device does not have a QE bit"), it is programmed to 111b ("Reserved").

2020-06-20afs: Fix hang on rmmod due to outstanding timerDavid Howells
The fileserver probe timer, net->fs_probe_timer, isn't cancelled when the kafs module is being removed and so the count it holds on net->servers_outstanding doesn't get dropped.. This causes rmmod to wait forever. The hung process shows a stack like: afs_purge_servers+0x1b5/0x23c [kafs] afs_net_exit+0x44/0x6e [kafs] ops_exit_list+0x72/0x93 unregister_pernet_operations+0x14c/0x1ba unregister_pernet_subsys+0x1d/0x2a afs_exit+0x29/0x6f [kafs] __do_sys_delete_module.isra.0+0x1a2/0x24b do_syscall_64+0x51/0x95 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Fix this by: (1) Attempting to cancel the probe timer and, if successful, drop the count that the timer was holding. (2) Make the timer function just drop the count and not schedule the prober if the afs portion of net namespace is being destroyed. Also, whilst we're at it, make the following changes: (3) Initialise net->servers_outstanding to 1 and decrement it before waiting on it so that it doesn't generate wake up events by being decremented to 0 until we're cleaning up. (4) Switch the atomic_dec() on ->servers_outstanding for ->fs_timer in afs_purge_servers() to use the helper function for that.

2020-06-20afs: Fix afs_do_lookup() to call correct fetch-status op variantDavid Howells
Fix afs_do_lookup()'s fallback case for when FS.InlineBulkStatus isn't supported by the server. In the fallback, it calls FS.FetchStatus for the specific vnode it's meant to be looking up. Commit b6489a49f7b7 broke this by renaming one of the two identically-named afs_fetch_status_operation descriptors to something else so that one of them could be made non-static. The site that used the renamed one, however, wasn't renamed and didn't produce any warning because the other was declared in a header. Fix this by making afs_do_lookup() use the renamed variant. Note that there are two variants of the success method because one is called from ->lookup() where we may or may not have an inode, but can't call iget until after we've talked to the server - whereas the other is called from within iget where we have an inode, but it may or may not be initialised. The latter variant expects there to be an inode, but because it's being called from there former case, there might not be - resulting in an oops like the following: BUG: kernel NULL pointer dereference, address: 00000000000000b0 ...

2020-06-19Merge branch 'for-5.8/papr_scm' into libnvdimm-for-nextDan Williams
Include the papr_scm health retrieval feature for v5.8-rc2. The functionality was initially posted well in advance of the merge window, but review comments and a late build-bot warning kept them out of the v5.8-rc1 libnvdimm pull request. Vaibhav notes: These patches are tied to specific features that were committed to customers in upcoming distros releases (RHEL and SLES) whose time-lines are tied to 5.8 kernel release. Being able to track the health of an nvdimm is critical for our customers that are running workloads leveraging papr-scm nvdimms. Missing the 5.8 kernel would mean missing the distro timelines and shifting forward the availability of this feature in distro kernels by at least 6 months.
