2025-01-17block: Add common atomic writes enable flagJohn Garry
Currently only stacked devices need to explicitly enable atomic writes by setting BLK_FEAT_ATOMIC_WRITES_STACKED flag. This does not work well for device mapper stacking devices, as there many sets of limits are stacked and what is the 'bottom' and 'top' device can swapped. This means that BLK_FEAT_ATOMIC_WRITES_STACKED needs to be set for many queue limits, which is messy. Generalize enabling atomic writes enabling by ensuring that all devices must explicitly set a flag - that includes NVMe, SCSI sd, and md raid.

Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4.

2025-01-17pmdomain: arm: scmi_pm_domain: Send an explicit request to set the current stateSudeep Holla
On a system with multiple active SCMI agents, one agent(other than OSPM/ Linux or bootloader) would request to turn on a shared power domain before the Linux boots/initialise the genpds. So when the Linux boots and gets the power state as already ON, it just registers the genpd with a default ON state. However, when the driver that needs this shared power domain is probed genpd sees that the power domain status is ON and never makes any SCMI call to power it up which is correct. But, since Linux didn't make an explicit request to turn on the shared power domain, the SCMI platform firmware will not know if the OSPM agent is actively using it. Suppose the other agent that requested the shared power domain to be powered ON requests to power it OFF as it no longer needs it, the SCMI platform firmware needs to turn it off if there are no active users of it which in the above scenaro is the case. As a result of SCMI platform firmware turning off the resource, OSPM/ Linux will crash the moment as it expects the shared power domain to be powered ON. Send an explicit request to set the current state when setting up the genpd power domains so that OSPM registers its vote in the power domain state with the SCMI platform firmware. The other option is to not read the state and set the genpds as default OFF, but it can't handle the scenario on certain platforms where SCMI platform keeps all the power domains turned ON by default for faster boot (or any other such variations) and expect the OSPM to turn off the unused domains if power saving is required.

2025-01-17iommu/amd: Remove type argument from do_iommu_domain_alloc() and relatedJason Gunthorpe
do_iommu_domain_alloc() is only called from amd_iommu_domain_alloc_paging_flags() so type is always IOMMU_DOMAIN_UNMANAGED. Remove type and all the dead conditionals checking it. IOMMU_DOMAIN_IDENTITY checks are similarly obsolete as the conversion to the global static identity domain removed those call paths. The caller of protection_domain_alloc() should set the type, fix the miss in the SVA code.

2025-01-17iommu/amd: Remove dev == NULL checksJason Gunthorpe
This is no longer possible, amd_iommu_domain_alloc_paging_flags() is never called with dev = NULL from the core code. Similarly get_amd_iommu_from_dev() can never be NULL either.

2025-01-17iommu/amd: Remove domain_alloc()Jason Gunthorpe
IOMMU drivers should not be sensitive to the domain type, a paging domain should be created based only on the flags passed in, the same for all callers. AMD was using the domain_alloc() path to force VFIO into a v1 domain type, because v1 gives higher performance. However now that IOMMU_HWPT_ALLOC_PASID is present, and a NULL device is not possible, domain_alloc_paging_flags() will do the right thing for VFIO. When invoked from VFIO flags will be 0 and the amd_iommu_pgtable type of domain will be selected. This is v1 by default unless the kernel command line has overridden it to v2. If the admin is forcing v2 assume they know what they are doing so force it everywhere, including for VFIO.

Add simple CPU Freq driver for Airoha EN7581 SoC that control CPU frequency scaling with SMC APIs and register a generic "cpufreq-dt" device. All CPU share the same frequency and can't be controlled independently. CPU frequency is controlled by the attached PM domain. Add SoC compatible to cpufreq-dt-plat block list as a dedicated cpufreq driver is needed with OPP v2 nodes declared in DTS.

2025-01-16net: stmmac: convert to phylink managed EEE supportRussell King (Oracle)
Convert stmmac to use phylink managed EEE support rather than delving into phylib: 1. Move the stmmac_eee_init() calls out of mac_link_down() and mac_link_up() methods into the new mac_{enable,disable}_lpi() methods. We leave the calls to stmmac_set_eee_pls() in place as these change bits which tell the EEE hardware when the link came up or down, and is used for a separate hardware timer. However, symmetrically conditionalise this with priv->dma_cap.eee. 2. Update the current LPI timer each time LPI is enabled - which we need for software-timed LPI. 3. With phylink managed EEE, phylink manages the receive clock stop configuration via phylink_config.eee_rx_clk_stop_enable. Set this appropriately which makes the call to phy_eee_rx_clock_stop() redundant. 4. From what I can work out, all supported interfaces support LPI signalling on stmmac (there's no restriction implemented.) It also appears to support LPI at all full duplex speeds at or over 100M. Set these capabilities. 5. The default timer appears to be derived from a module parameter. Set this the same, although we keep code that reconfigures the timer in stmmac_init_phy(). 6. Remove the direct call to phy_support_eee(), which phylink will do on the drivers behalf if phylink_config.eee_enabled_default is set.

2025-01-16net: mvpp2: add EEE implementationRussell King (Oracle)
Add EEE support for mvpp2, using phylink's EEE implementation, which means we just need to implement the two methods for LPI control, and with the initial configuration. Only SGMII mode is supported, so only 100M and 1G speeds. Disabling LPI requires clearing a single bit. Enabling LPI needs a full configuration of several values, as the timer values are dependent on the MAC operating speed.
