2025-03-11arm64/boot: Enable EL2 requirements for FEAT_PMUv3p9Anshuman Khandual
FEAT_PMUv3p9 registers such as PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 access from EL1 requires appropriate EL2 fine grained trap configuration via FEAT_FGT2 based trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2. Otherwise such register accesses will result in traps into EL2. Add a new helper __init_el2_fgt2() which initializes FEAT_FGT2 based fine grained trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2 (setting the bits nPMICNTR_EL0, nPMICFILTR_EL0 and nPMUACR_EL1) to enable access into PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 registers. Also update booting.rst with SCR_EL3.FGTEn2 requirement for all FEAT_FGT2 based registers to be accessible in EL2.

2025-03-11wifi: iwlwifi: mld: avoid selecting bad linksMiri Korenblit
Currently, we don't select a link that wasn't heared in the last 5 seconds. But if the link started to suffer from missed beacons more recent than that, we might select this link even we really shouldn't, leading to a disconnection instead of a link switch. Fix this by checking if a link was heared in the last MLO scan, if not - don't include it in the link selection. Since we do an MLO scan on missed beacons, we will not hear that link in that scan, and won't select it.

According to the requirements, if the last scan isn't older than 20 seconds, we can use its results and do the link selection without scanning before. But this applies only when trying to get back to EMLSR, not if the link has bad RSSI/missed beacons. Since an MLO scan is cheap anyway, and results from 20 seconds before are really old, always scan before links switching.

Due to the iwl_mld_get_chandef_from_chanctx() logic, even after the OMI handshake to reduce bandwidth the driver wouldn't apply that to the PHY context, since it always uses the normal, not the reduced, configuration on 6 GHz (not strictly always, but OMI will only apply if the original bandwidth is > 80 MHz.)

2025-03-11arm64: realm: Use aliased addresses for device DMA to shared buffersSuzuki K Poulose
When a device performs DMA to a shared buffer using physical addresses, (without Stage1 translation), the device must use the "{I}PA address" with the top bit set in Realm. This is to make sure that a trusted device will be able to write to shared buffers as well as the protected buffers. Thus, a Realm must always program the full address including the "protection" bit, like AMD SME encryption bits. Enable this by providing arm64 specific dma_addr_{encrypted, canonical} helpers for Realms. Please note that the VMM needs to similarly make sure that the SMMU Stage2 in the Non-secure world is setup accordingly to map IPA at the unprotected alias.

AMD SME added __sme_set/__sme_clr primitives to modify the DMA address for encrypted/decrypted traffic. However this doesn't fit in with other models, e.g., Arm CCA where the meanings are the opposite. i.e., "decrypted" traffic has a bit set and "encrypted" traffic has the top bit cleared. In preparation for adding the support for Arm CCA DMA conversions, convert the existing primitives to more generic ones that can be provided by the backends. i.e., add helpers to 1. dma_addr_encrypted - Convert a DMA address to "encrypted" [ == __sme_set() ] 2. dma_addr_unencrypted - Convert a DMA address to "decrypted" [ None exists today ] 3. dma_addr_canonical - Clear any "encryption"/"decryption" bits from DMA address [ SME uses __sme_clr() ] and convert to a canonical DMA address. Since the original __sme_xxx helpers come from linux/mem_encrypt.h, use that as the home for the new definitions and provide dummy ones when none is provided by the architectures. With the above, phys_to_dma_unencrypted() uses the newly added dma_addr_unencrypted() helper and to make it a bit more easier to read and avoid double conversion, provide __phys_to_dma().

2025-03-11platform/x86/amd/pmf: fix cleanup in amd_pmf_init_smart_pc()Dan Carpenter
There are a few problems in this code: First, if amd_pmf_tee_init() fails then the function returns directly instead of cleaning up. We cannot simply do a "goto error;" because the amd_pmf_tee_init() cleanup calls tee_shm_free(dev->fw_shm_pool); and amd_pmf_tee_deinit() calls it as well leading to a double free. I have re-written this code to use an unwind ladder to free the allocations. Second, if amd_pmf_start_policy_engine() fails on every iteration though the loop then the code calls amd_pmf_tee_deinit() twice which is also a double free. Call amd_pmf_tee_deinit() inside the loop for each failed iteration. Also on that path the error codes are not necessarily negative kernel error codes. Set the error code to -EINVAL. There is a very subtle third bug which is that if the call to input_register_device() in amd_pmf_register_input_device() fails then we call input_unregister_device() on an input device that wasn't registered. This will lead to a reference counting underflow because of the device_del(&dev->dev) in __input_unregister_device(). It's unlikely that anyone would ever hit this bug in real life.

2025-03-11dma: Fix encryption bit clearing for dma_to_physSuzuki K Poulose
phys_to_dma() sets the encryption bit on the translated DMA address. But dma_to_phys() clears the encryption bit after it has been translated back to the physical address, which could fail if the device uses DMA ranges. AMD SME doesn't use the DMA ranges and thus this is harmless. But as we are about to add support for other architectures, let us fix this.

2025-03-11nvme: move error logging from nvme_end_req() to __nvme_end_req()Shin'ichiro Kawasaki
Before the Commit 1f47ed294a2b ("block: cleanup and fix batch completion adding conditions"), blk_mq_add_to_batch() did not add failed passthrough requests to batch, and returned false. After the commit, blk_mq_add_to_batch() always adds passthrough requests to batch regardless of whether the request failed or not, and returns true. This affected error logging feature in the NVME driver. Before the commit, the call chain of failed passthrough request was as follows: nvme_handle_cqe() blk_mq_add_to_batch() .. false is returned, then call nvme_pci_complete_rq() nvme_pci_complete_rq() nvme_complete_rq() nvme_end_req() nvme_log_err_passthru() .. error logging __nvme_end_req() .. end of the rqeuest After the commit, the call chain is as follows: nvme_handle_cqe() blk_mq_add_to_batch() .. true is returned, then set nvme_pci_complete_batch() .. nvme_pci_complete_batch() nvme_complete_batch() nvme_complete_batch_req() __nvme_end_req() .. end of the request, without error logging To make the error logging feature work again for passthrough requests, move the nvme_log_err_passthru() call from nvme_end_req() to __nvme_end_req(). While at it, move nvme_log_error() call for non-passthrough requests together with nvme_log_err_passthru(). Even though the trigger commit does not affect non-passthrough requests, move it together for code simplicity.

2025-03-11iommu/arm-smmu: Set rpm auto_suspend once during probePranjal Shrivastava
The current code calls arm_smmu_rpm_use_autosuspend() during device attach, which seems unusual as it sets the autosuspend delay and the 'use_autosuspend' flag for the smmu device. These parameters can be simply set once during the smmu probe and in order to avoid bouncing rpm states, we can simply mark_last_busy() during a client dev attach as discussed in [1]. Move the handling of arm_smmu_rpm_use_autosuspend() to the SMMU probe and modify the arm_smmu_rpm_put() function to mark_last_busy() before calling __pm_runtime_put_autosuspend(). Additionally, s/pm_runtime_put_autosuspend/__pm_runtime_put_autosuspend/ to help with the refactor of the pm_runtime_put_autosuspend() API [2].
