2023-02-03net: phylink: move phy_device_free() to correctly release phy deviceClément Léger
After calling fwnode_phy_find_device(), the phy device refcount is incremented. Then, when the phy device is attached to a netdev with phy_attach_direct(), the refcount is also incremented but only decremented in the caller if phy_attach_direct() fails. Move phy_device_free() before the "if" to always release it correctly. Indeed, either phy_attach_direct() failed and we don't want to keep a reference to the phydev or it succeeded and a reference has been taken internally.

2023-02-02of/address: Return an error when no valid dma-ranges are foundMark Brown
Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range") converted the parsing of dma-range properties to use code shared with the PCI range parser. The intent was to introduce no functional changes however in the case where we fail to translate the first resource instead of returning -EINVAL the new code we return 0. Restore the previous behaviour by returning an error if we find no valid ranges, the original code only handled the first range but subsequently support for parsing all supplied ranges was added. This avoids confusing code using the parsed ranges which doesn't expect to successfully parse ranges but have only a list terminator returned, this fixes breakage with so far as I can tell all DMA for on SoC devices on the Socionext Synquacer platform which has a firmware supplied DT. A bisect identified the original conversion as triggering the issues there.

2023-02-02clocksource: Verify HPET and PMTMR when TSC unverifiedPaul E. McKenney
On systems with two or fewer sockets, when the boot CPU has CONSTANT_TSC, NONSTOP_TSC, and TSC_ADJUST, clocksource watchdog verification of the TSC is disabled. This works well much of the time, but there is the occasional production-level system that meets all of these criteria, but which still has a TSC that skews significantly from atomic-clock time. This is usually attributed to a firmware or hardware fault. Yes, the various NTP daemons do express their opinions of userspace-to-atomic-clock time skew, but they put them in various places, depending on the daemon and distro in question. It would therefore be good for the kernel to have some clue that there is a problem. The old behavior of marking the TSC unstable is a non-starter because a great many workloads simply cannot tolerate the overheads and latencies of the various non-TSC clocksources. In addition, NTP-corrected systems sometimes can tolerate significant kernel-space time skew as long as the userspace time sources are within epsilon of atomic-clock time. Therefore, when watchdog verification of TSC is disabled, enable it for HPET and PMTMR (AKA ACPI PM timer). This provides the needed in-kernel time-skew diagnostic without degrading the system's performance. Signed-off-by: Paul E.

Fix this by copying the string to a kmalloc'ed buffer. - The diag288_wdt watchdog module does not indicate that it accesses memory from an inline assembly, which it does. Add "memory" to the clobber list to prevent the compiler from optimizing code incorrectly away. - Pass size of the uncompressed kernel image to __decompress() call.

2023-02-02powercap: idle_inject: Add update callbackSrinivas Pandruvada
The powercap/idle_inject core uses play_idle_precise() to inject idle time. But play_idle_precise() can't ensure that the CPU is fully idle for the specified duration because of wakeups due to interrupts. To compensate for the reduced idle time due to these wakes, the caller can adjust requested idle time for the next cycle. The goal of idle injection is to keep system at some idle percent on average, so this is fine to overshoot or undershoot instantaneous idle times. The idle inject core provides an interface idle_inject_set_duration() to set idle and runtime duration. Some architectures provide interface to get actual idle time observed by the hardware. So, the effective idle percent can be adjusted using the hardware feedback. For example, Intel CPUs provides package idle counters, which is currently used by Intel powerclamp driver to readjust runtime duration. When the caller's desired idle time over a period is less or greater than the actual CPU idle time observed by the hardware, caller can readjust idle and runtime duration for the next cycle. The only way this can be done currently is by monitoring hardware idle time from a different software thread and readjust idle and runtime duration using idle_inject_set_duration(). This can be avoided by adding a callback which callers can register and readjust from this callback function. Add a capability to register an optional update() callback, which can be called from the idle inject core before waking up CPUs for idle injection. This callback can be registered via a new interface: idle_inject_register_full(). During this process of constantly adjusting idle and runtime duration there can be some cases where actual idle time is more than the desired. In this case idle inject can be skipped for a cycle. If update() callback returns false, then the idle inject core skips waking up CPUs for the idle injection.

2023-02-02thermal: intel: powerclamp: Fix cur_state for multi package systemSrinivas Pandruvada
The powerclamp cooling device cur_state shows actual idle observed by package C-state idle counters. But the implementation is not sufficient for multi package or multi die system. The cur_state value is incorrect. On these systems, these counters must be read from each package/die and somehow aggregate them. But there is no good method for aggregation. It was not a problem when explicit CPU model addition was required to enable intel powerclamp. In this way certain CPU models could have been avoided. But with the removal of CPU model check with the availability of Package C-state counters, the driver is loaded on most of the recent systems. For multi package/die systems, just show the actual target idle state, the system is trying to achieve. In powerclamp this is the user set state minus one. Also there is no use of starting a worker thread for polling package C-state counters and applying any compensation for multiple package or multiple die systems.

The code expect the PHY to be in power down which is only true after reset. Allow changes of the SGMII parameters more than once. Only power down when reconfiguring to avoid bouncing the link when there's no reason to - based on code from Russell King. There are cases when the SGMII_PHYA_PWD register contains 0x9 which prevents SGMII from working. The SGMII still shows link but no traffic can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was taken from a good working state of the SGMII interface.

2023-02-02ata: libata: Fix sata_down_spd_limit() when no link speed is reportedDamien Le Moal
Commit 2dc0b46b5ea3 ("libata: sata_down_spd_limit should return if driver has not recorded sstatus speed") changed the behavior of sata_down_spd_limit() to return doing nothing if a drive does not report a current link speed, to avoid reducing the link speed to the lowest 1.5 Gbps speed. However, the change assumed that a speed was recorded before probing (e.g. before a suspend/resume) and set in link->sata_spd. This causes problems with adapters/drives combination failing to establish a link speed during probe autonegotiation. One example reported of this problem is an mvebu adapter with a 3Gbps port-multiplier box: autonegotiation fails, leaving no recorded link speed and no reported current link speed. Probe retries also fail as no action is taken by sata_set_spd() after each retry. Fix this by returning early in sata_down_spd_limit() only if we do have a recorded link speed, that is, if link->sata_spd is not 0. With this fix, a failed probe not leading to a recorded link speed is retried at the lower 1.5 Gbps speed, with the link speed potentially increased later on the second revalidate of the device if the device reports that it supports higher link speeds.

2023-02-02hv_netvsc: Fix missed pagebuf entries in netvsc_dma_map/unmap()Michael Kelley
netvsc_dma_map() and netvsc_dma_unmap() currently check the cp_partial flag and adjust the page_count so that pagebuf entries for the RNDIS portion of the message are skipped when it has already been copied into a send buffer. But this adjustment has already been made by code in netvsc_send(). The duplicate adjustment causes some pagebuf entries to not be mapped. In a normal VM, this doesn't break anything because the mapping doesn’t change the PFN. But in a Confidential VM, dma_map_single() does bounce buffering and provides a different PFN. Failing to do the mapping causes the wrong PFN to be passed to Hyper-V, and various errors ensue. Fix this by removing the duplicate adjustment in netvsc_dma_map() and netvsc_dma_unmap().
