Uncore P1 is not uncore minmum frequency. This is uncore base frequency. Correct display from uncore-frequency-min(MHz) to uncore-frequency-base(Mhz). To get uncore min frequency use mailbox command CONFIG_TDP_GET_RATIO_INFO. Use this mailbox to get uncore frequency limits when present. Signed-off-by:

When SMT is disabled from kernel command line, sibling CPUs still appears in the sysfs as offline CPUs. This is a problem when turbo-freq is enabled in auto mode. They are still assigned to CLOS value of 3 as they are still in the present CPU list. But they are not in the sibling list of a CPU. When the CPU is a high priority CPU, because of sibling it will be still set to CLOS to 3 as CLOS is assigned at core level not at CPU level. So, avoid setting CLOS 3 to offline CPU. Signed-off-by:

Due to some recent kernel changes, reading cpufreq attributes like scaling_max_freq on offline CPUs returns error. So avoid reading cpufreq attributes on offline CPUs. Signed-off-by:

struct isst_id *id is a pointer, comparing it with less than zero is wrong. The check is there to make sure the id->pkg and id->die is set to -1, when it is illegal or unavailable. Here comparing with MAX_PACKAGE_COUNT and MAX_DIE_PER_PACKAGE is sufficient. Hence remove the wrong check. Signed-off-by:

Follow up from https://lore.kernel.org/all/20230120221214.24426-1-rishitbansal0@gmail.com/ There is a "Win-Lock" key on HP Omen Laptops which supports enabling and disabling the Windows key, which trigger commands 0x21a4 and 0x121a4 respectively. Currently the hp-wmi driver throws warnings for this event. These can be ignored using KE_IGNORE as the functionality is handled by the keyboard firmware itself. Signed-off-by:

We currently have a struct ssam_request_sync and a function ssam_request_sync(). While this is valid C, there are some downsides to it. One of these is that current Sphinx versions (>= 3.0) cannot disambiguate between the two (see disucssion and pull request linked below). It instead emits a "WARNING: Duplicate C declaration" and links for the struct and function in the resulting documentation link to the same entry (i.e. both to either function or struct documentation) instead of their respective own entries. While we could just ignore that and wait for a fix, there's also a point to be made that the current naming can be somewhat confusing when searching (e.g. via grep) or trying to understand the levels of abstraction at play: We currently have struct ssam_request_sync and associated functions ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct. However, function ssam_request_sync() is one abstraction level above this. Similarly, ssam_request_sync_with_buffer() is not a function operating on struct ssam_request_sync, but rather a sibling to ssam_request_sync(), both using the struct under the hood. Therefore, rename the top level request functions: ssam_request_sync() -> ssam_request_do_sync() ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer() ssam_request_sync_onstack() -> ssam_request_do_sync_onstack() Link: https://lore.kernel.org/all/085e0ada65c11da9303d07e70c510dc45f21315b.1656756450.git.mchehab@kernel.org/ Link: https://github.com/sphinx-doc/sphinx/pull/8313Signed-off-by:

The target ID of the base hub is currently set to KIP (keyboard/ peripherals). However, even though it manages such devices with the KIP target ID, the base hub itself is actually accessed via the SAM target ID. So set it accordingly. Note that the target ID of the hub can be chosen arbitrarily and does not directly correspond to any physical or virtual component of the EC. This change is only a code improvement intended for consistency and clarity, it does not fix an actual bug. Signed-off-by:

Similar to the target category (TC), the target ID (TID) can be one value out of a small number of choices, given in enum ssam_ssh_tid. In the device ID macros, SSAM_SDEV() and SSAM_VDEV() we already use text expansion to, both, remove some textual clutter for the target category values and enforce that the value belongs to the known set. Now that we know the names for the target IDs, use the same trick for them as well. Also rename the SSAM_ANY_x macros to SSAM_SSH_x_ANY to better fit in. Signed-off-by:

Add command source and target IDs to trace events. Tracing support for the Surface Aggregator driver was originally implemented at a time when only two peers were known: Host and SAM. We now know that there are at least five, with three actively being used (Host, SAM, KIP; four with Debug if you want to count manually enabling that interface). So it makes sense to also explicitly name the peers involved when tracing. Signed-off-by:

The `tid_in` and `tid_out` fields of the serial hub protocol command struct (struct ssh_command) are actually source and target IDs, indicating the peer from which the message originated and the peer for which it is intended. Change the naming of those fields accordingly and improve the protocol documentation. Additionally, introduce an enum containing all currently known peers, i.e. targets and sources. Signed-off-by:

Every power mode of static power slider has its own AC and DC power settings. When the power source changes from AC to DC, corresponding DC thermals were not updated from PMF config store and this leads the system to always run on AC power settings. Fix it by registering with power_supply notifier and apply DC settings upon getting notified by the power_supply handler.

My last commit to fix profile mode displays on AMD platforms caused an issue on Intel platforms - sorry! In it I was reading the current functional mode (MMC, PSC, AMT) from the BIOS but didn't account for the fact that on some of our Intel platforms I use a different API which returns just the profile and not the functional mode. This commit fixes it so that on Intel platforms it knows the functional mode is always MMC. I also fixed a potential problem that a platform may try to set the mode for both MMC and PSC - which was incorrect. Tested on X1 Carbon 9 (Intel) and Z13 (AMD).

Some apple laptop models have an ACPI device with a HID of APP000B and that device has an IO resource (so it does not describe the new unsupported MMIO based gmux type), but there actually is no gmux in the laptop at all. The gmux_probe() function of the actual apple-gmux driver has code to detect this, this code has been factored out into a new apple_gmux_detect() helper in apple-gmux.h. Use this new function to fix acpi_video_get_backlight_type() wrongly returning apple_gmux as type on the following laptops: MacBookPro5,4 https://pastebin.com/8Xjq7RhS MacBookPro8,1 https://linux-hardware.org/?probe=e513cfbadb&log=dmesg MacBookPro9,2 https://bugzilla.kernel.org/attachment.cgi?id=278961 MacBookPro10,2 https://lkml.org/lkml/2014/9/22/657 MacBookPro11,2 https://forums.fedora-fr.org/viewtopic.php?id=70142 MacBookPro11,4 https://raw.githubusercontent.com/im-0/investigate-card-reader-suspend-problem-on-mbp11.4/mast Fixes: 21245df3 ("ACPI: video: Add Apple GMUX brightness control detection") Link: https://lore.kernel.org/platform-driver-x86/20230123113750.462144-1-hdegoede@redhat.com/Reported-by:

Add a new (static inline) apple_gmux_detect() helper to apple-gmux.h which can be used for gmux detection instead of apple_gmux_present(). The latter is not really reliable since an ACPI device with a HID of APP000B is present on some devices without a gmux at all, as well as on devices with a newer (unsupported) MMIO based gmux model. This causes apple_gmux_present() to return false-positives on a number of different Apple laptop models. This new helper uses the same probing as the actual apple-gmux driver, so that it does not return false positives. To avoid code duplication the gmux_probe() function of the actual driver is also moved over to using the new apple_gmux_detect() helper. This avoids false positives (vs _HID + IO region detection) on: MacBookPro5,4 https://pastebin.com/8Xjq7RhS MacBookPro8,1 https://linux-hardware.org/?probe=e513cfbadb&log=dmesg MacBookPro9,2 https://bugzilla.kernel.org/attachment.cgi?id=278961 MacBookPro10,2 https://lkml.org/lkml/2014/9/22/657 MacBookPro11,2 https://forums.fedora-fr.org/viewtopic.php?id=70142 MacBookPro11,4 https://raw.githubusercontent.com/im-0/investigate-card-reader-suspend-problem-on-mbp11.4/master/test-16/dmesg Fixes: 21245df3 ("ACPI: video: Add Apple GMUX brightness control detection") Link: https://lore.kernel.org/platform-driver-x86/20230123113750.462144-1-hdegoede@redhat.com/Reported-by:
