2024-05-31ata: libata-core: Add ATA_HORKAGE_NOLPM for Crucial CT240BX500SSD1Niklas Cassel
Commit 7627a0edef54 ("ata: ahci: Drop low power policy board type") dropped the board_ahci_low_power board type, and instead enables LPM if: -The AHCI controller reports that it supports LPM (Partial/Slumber), and -CONFIG_SATA_MOBILE_LPM_POLICY != 0, and -The port is not defined as external in the per port PxCMD register, and -The port is not defined as hotplug capable in the per port PxCMD register. Partial and Slumber LPM states can either be initiated by HIPM or DIPM. For HIPM (host initiated power management) to get enabled, both the AHCI controller and the drive have to report that they support HIPM. For DIPM (device initiated power management) to get enabled, only the drive has to report that it supports DIPM. However, the HBA will reject device requests to enter LPM states which the HBA does not support. The problem is that Crucial CT240BX500SSD1 drives do not handle low power modes correctly. The problem was most likely not seen before because no one had used this drive with a AHCI controller with LPM enabled. Add a quirk so that we do not enable LPM for this drive, since we see command timeouts if we do (even though the drive claims to support DIPM).

We'll need to start identifying the platforms independently in display code in order to break free from the i915 and xe IS_<PLATFORM>() macros. This is fairly straightforward, as we already identify most platforms by PCI ID in display probe anyway. As the first step, add platform descriptors with pointers to display info. We'll have more platforms than display info, so minimize duplication: - Add separate skl/kbl/cfl/cml descriptors while they share the display info. - Add separate jsl/ehl descriptors while they share the display info.

kvm_riscv_vcpu_set_reg_isa_ext function In the function kvm_riscv_vcpu_set_reg_isa_ext, the original code used incorrect reg_subtype labels KVM_REG_RISCV_SBI_MULTI_EN/DIS. These have been corrected to KVM_REG_RISCV_ISA_MULTI_EN/DIS respectively. Although they are numerically equivalent, the actual processing will not result in errors, but it may lead to ambiguous code semantics.

2024-05-31RISC-V: KVM: No need to use mask when hart-index-bit is 0Yong-Xuan Wang
When the maximum hart number within groups is 1, hart-index-bit is set to 0. Consequently, there is no need to restore the hart ID from IMSIC addresses and hart-index-bit settings. Currently, QEMU and kvmtool do not pass correct hart-index-bit values when the maximum hart number is a power of 2, thereby avoiding this issue. Corresponding patches for QEMU and kvmtool will also be dispatched.

2024-05-30blk-throttle: Fix incorrect display of io.maxWaiman Long
Commit bf20ab538c81 ("blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW") attempts to revert the code change introduced by commit cd5ab1b0fcb4 ("blk-throttle: add .low interface"). However, it leaves behind the bps_conf[] and iops_conf[] fields in the throtl_grp structure which aren't set anywhere in the new blk-throttle.c code but are still being used by tg_prfill_limit() to display the limits in io.max. Now io.max always displays the following values if a block queue is used: <m>:<n> rbps=0 wbps=0 riops=0 wiops=0 Fix this problem by removing bps_conf[] and iops_conf[] and use bps[] and iops[] instead to complete the revert.

2024-05-30of: property: Fix fw_devlink handling of interrupt-mapMarc Zyngier
Commit d976c6f4b32c ("of: property: Add fw_devlink support for interrupt-map property") tried to do what it says on the tin, but failed on a couple of points: - it confuses bytes and cells. Not a huge deal, except when it comes to pointer arithmetic - it doesn't really handle anything but interrupt-maps that have their parent #address-cells set to 0 The combinations of the two leads to some serious fun on my M1 box, with plenty of WARN-ON() firing all over the shop, and amusing values being generated for interrupt specifiers. Having 2 versions of parsing code for "interrupt-map" was a bad idea. Now that the common parsing parts have been refactored into of_irq_parse_imap_parent(), rework the code here to use it instead and fix the pointer arithmetic. Note that the dependency will be a bit different than the original code when the interrupt-map points to another interrupt-map. In this case, the original code would resolve to the final interrupt controller. Now the dependency is the parent interrupt-map (which itself should have a dependency to the parent). It is possible that a node with an interrupt-map has no driver.

of_irq_parse_raw() Factor out the parsing of interrupt-map interrupt parent phandle and its arg cells to a separate function, of_irq_parse_imap_parent(), so that it can be used in other parsing scenarios (e.g. fw_devlink). There was a refcount leak on non-matching entries when iterating thru "interrupt-map" which is fixed.
