2023-02-17i2c: i801: Centralize configuring non-block commands in i801_simple_transactionHeiner Kallweit
Currently configuring command register settings is distributed over multiple functions. At first centralize this for non-block commands in i801_simple_transaction().

2023-02-17i2c: i801: Handle SMBAUXCTL_E32B in i801_block_transaction_by_block onlyHeiner Kallweit
Currently we touch SMBAUXCTL even if not needed. That's the case for block commands that don't use block buffer mode, either because block buffer mode isn't available or because it's not supported for the respective command (e.g. I2C block transfer). Improve this by setting/resetting SMBAUXCTL_E32B in i801_block_transaction_by_block() only. Small downside is that we now access SMBAUXCTL twice for transactions that use PEC and block buffer mode. But this should a rather rare case and the impact is negligible.

2023-02-17IB/hfi1: Fix sdma.h tx->num_descs off-by-one errorsPatrick Kelsey
Fix three sources of error involving struct sdma_txreq.num_descs. When _extend_sdma_tx_descs() extends the descriptor array, it uses the value of tx->num_descs to determine how many existing entries from the tx's original, internal descriptor array to copy to the newly allocated one. As this value was incremented before the call, the copy loop will access one entry past the internal descriptor array, copying its contents into the corresponding slot in the new array. If the call to _extend_sdma_tx_descs() fails, _pad_smda_tx_descs() then invokes __sdma_tx_clean() which uses the value of tx->num_desc to drive a loop that unmaps all descriptor entries in use. As this value was incremented before the call, the unmap loop will invoke sdma_unmap_desc() on a descriptor entry whose contents consist of whatever random data was copied into it during (1), leading to cascading further calls into the kernel and driver using arbitrary data. _sdma_close_tx() was using tx->num_descs instead of tx->num_descs - 1. Fix all of the above by: - Only increment .num_descs after .descp is extended. - Use .num_descs - 1 instead of .num_descs for last .descp entry.

2023-02-17RDMA/irdma: Add support for dmabuf pin memory regionsZhu Yanjun
This is a followup to the EFA dmabuf[1]. Irdma driver currently does not support on-demand-paging(ODP). So it uses habanalabs as the dmabuf exporter, and irdma as the importer to allow for peer2peer access through libibverbs. In this commit, the function ib_umem_dmabuf_get_pinned() is used. This function is introduced in EFA dmabuf[1] which allows the driver to get a dmabuf umem which is pinned and does not require move_notify callback implementation. The returned umem is pinned and DMA mapped like standard cpu umems, and is released through ib_umem_release().

2023-02-17dm ioctl: remove unnecessary check when using dm_get_mdptr()Hou Tao
__hash_remove() removes hash_cell with _hash_lock locked, so acquiring _hash_lock can guarantee no-NULL hc returned from dm_get_mdptr() must have not been removed and hc->md must still be md. __hash_remove() also acquires dm_hash_cells_mutex before setting mdptr as NULL. So in dm_copy_name_and_uuid(), after acquiring dm_hash_cells_mutex and ensuring returned hc is not NULL, the returned hc must still be alive and hc->md must still be md. Remove the unnecessary hc->md != md checks when using dm_get_mdptr() with _hash_lock or dm_hash_cells_mutex acquired.

After a check of the manual it becomes obvious that the calculations in .apply() are totally bogus: FreqPWMOutx was always written as zero, so the period was fixed at 3413333.33 ns. However state->period wasn't checked at all. The lower 10 bits of duty_cycle were just used as DutyPWMOutx. So if a duty cycle of 512 ns (or 1536 ns) was requested, it actually programmed 1710000 ns.

2023-02-17PCI: Remove MODULE_LICENSE so boolean drivers don't look like modulesNick Alcock
Since 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, MODULE_LICENSE in non-modules causes modprobe to misidentify the object file as a module when it is not, and modprobe might succeed rather than failing with a suitable error message. For tristate modules that can be either built-in or loaded at runtime, modprobe succeeds in both cases: # modprobe ext4 [exit status zero if CONFIG_EXT4_FS=y or =m] For boolean modules like the Standard Hot Plug Controller driver (shpchp) that cannot be loaded at runtime, modprobe should always fail like this: # modprobe shpchp modprobe: FATAL: Module shpchp not found in directory /lib/modules/... [exit status non-zero regardless of CONFIG_HOTPLUG_PCI_SHPC] but prior to this commit, shpchp_core.c contained MODULE_LICENSE, so "modprobe shpchp" silently succeeded when it should have failed. Remove MODULE_LICENSE in files that cannot be built as modules.

2023-02-16PCI: hv: Drop duplicate PCI_MSI dependencyLukas Bulwahn
Commit a474d3fbe287 ("PCI/MSI: Get rid of PCI_MSI_IRQ_DOMAIN") removed PCI_MSI_IRQ_DOMAIN and made all previous references to it refer to PCI_MSI instead. PCI_HYPERV_INTERFACE already depended on PCI_MSI && PCI_MSI_IRQ_DOMAIN, so we ended up with a redundant dependency on PCI_MSI && PCI_MSI. Drop the duplicate. No functional change. Just a stylistic clean-up.

A dereference of the __rcu pointer was noticed by sparse: drivers/pci/p2pdma.c:199:44: sparse: sparse: dereference of noderef expression Dereference the __rcu pointer using rcu_dereference_protected() instead of accessing it directly. It's safe to use rcu_dereference_protected() because a reference is held on the pgmap's percpu reference counter and thus it cannot disappear.

2023-02-16cxl/trace: Standardize device information outputIra Weiny
The trace points were written to take a struct device input for the trace. In CXL multiple device objects are associated with each CXL hardware device. Using different device objects in the trace point can lead to confusion for users. The PCIe device is nice to have, but the user space tooling relies on the memory device naming. It is better to have those device names reported. Change all trace points to take struct cxl_memdev as a standard and report that name. Furthermore, standardize on the name 'memdev' in both /sys/kernel/tracing/trace and cxl-cli monitor output.

2023-02-16arm_pmu: fix event CPU filteringMark Rutland
Janne reports that perf has been broken on Apple M1 as of commit: bd27568117664b8b ("perf: Rewrite core context handling") That commit replaced the pmu::filter_match() callback with pmu::filter(), whose return value has the opposite polarity, with true implying events should be ignored rather than scheduled. While an attempt was made to update the logic in armv8pmu_filter() and armpmu_filter() accordingly, the return value remains inverted in a couple of cases: * If the arm_pmu does not have an arm_pmu::filter() callback, armpmu_filter() will always return whether the CPU is supported rather than whether the CPU is not supported. As a result, the perf core will not schedule events on supported CPUs, resulting in a loss of events. Additionally, the perf core will attempt to schedule events on unsupported CPUs, but this will be rejected by armpmu_add(), which may result in a loss of events from other PMUs on those unsupported CPUs. * If the arm_pmu does have an arm_pmu::filter() callback, and armpmu_filter() is called on a CPU which is not supported by the arm_pmu, armpmu_filter() will return false rather than true. As a result, the perf core will attempt to schedule events on unsupported CPUs, but this will be rejected by armpmu_add(), which may result in a loss of events from other PMUs on those unsupported CPUs. This means a loss of events can be seen with any arm_pmu driver, but with the ARMv8 PMUv3 driver (which is the only arm_pmu driver with an arm_pmu::filter() callback) the event loss will be more limited and may go unnoticed, which is how this issue evaded testing so far. Fix the CPU filtering by performing this consistently in armpmu_filter(), and remove the redundant arm_pmu::filter() callback and armv8pmu_filter() implementation. Commit bd2756811766 also silently removed the CHAIN event filtering from armv8pmu_filter(), which will be addressed by a separate patch without using the filter callback.
