The P2SB could get an invalid BAR from the BIOS, and that won't be fixed up until pcibios_assign_resources(), which is an fs_initcall(). - Move p2sb_fs_init() to an fs_initcall_sync(). This is still early enough to avoid a race with any dependent drivers. - Add a check for IORESOURCE_UNSET in p2sb_valid_resource() to catch unset BARs going forward. - Return error values from p2sb_fs_init() so that the 'initcall_debug' cmdline arg provides useful data.

SST SST-BF and SST-TF can be enabled/disabled per SST-PP level. So return a mask of all levels, where the feature is supported, instead of just for level 0. Since the return value returns all levels mask, not just level 0, update API version. Signed-off-by:

SST BF and TF can be enabled/disabled per level. So check the current level support from the mask of supported levels. This change from a single level to mask for info.sst_tf_support and info.sst_tf_support is indicated by API version change. Use as mask for API version above 2. In this way there is no change in behavior when running on older kernel with API version 2. Since the tool can support now API version 3, update the supported API version. Signed-off-by:

A partitioned system has two different PCI VSEC devices per package. A non-partitioned device has only one PCI VSEC device per package. The current implementation only supports non partitioned systems. Each partition maps a set of power domains. Other than reading from different MMIO regions, there is no change in the SST functionality. The scope of SST control is still per power domain. Hence user space does not need to be aware of existence of partitions. With partitions, existing per package information defined using struct tpmi_sst_struct is enhanced to store information for both partitions. A mapping function map_partition_power_domain_id() is introduced, which maps to correct partition and index. This mapping function is called in get_instance() and isst_if_clos_assoc(), before indexing into tpmi_sst_struct->power_domain_info[]. The TPMI core platform info provides partition id and compute die ID mask for each partition. Use this information to order power domains, so that compute dies are presented before IO dies to match hardware defined compute die ID for each CPU. Signed-off-by:

TPMI information header added additional fields in version 2. Some of the reserved fields in version 1 are used to define new fields. Parse new fields and export as part of platform data. These fields include: - PCI segment ID - Partition ID of the package: If a package is represented by more than one PCI device, then partition ID along with cdie_mask, describes the scope. For example to update get/set properties for a compute die, one of the PCI MMIO region is selected from the partition ID. - cdie_mask: Mask of all compute dies in this partition. Signed-off-by:

Add a new driver for the MSI WMI Platform interface. The underlying ACPI WMI interface supports many features, but so far only reading of fan speed sensors is implemented. The driver was reverse-engineered based on a user request to the lm-sensors project, see the github issue for details. The ACPI WMI interface used by this driver seems to use the same embedded controller interface as the msi-ec driver, but supports automatic discovery of supported machines without relying on a DMI whitelist. The driver was tested by the user who created the github issue. Closes: https://github.com/lm-sensors/lm-sensors/issues/475Signed-off-by:

Lenovo trackpoints are adding the ability to generate a doubletap event. This handles the doubletap event and sends the KEY_PROG4 event to userspace. Despite the driver itself not using KEY_PROG1 - KEY_PROG3 this still uses KEY_PROG4 because of some keys being remapped to KEY_PROG1 - KEY_PROG3 by default by the upstream udev hwdb containing: evdev:name:ThinkPad Extra Buttons:dmi:bvn*:bvr*:bd*:svnLENOVO*:pn*:* ...

The X1 carbon 2014 / 2nd gen's adaptive keyboard top row's "Home" mode, which is 1 of the 2 modes Linux supports, has clipping-tool and cloud buttons which so far are not mapped. I assume these were left as KEY_RESERVED because no suitable KEY_FOO codes were available when support was added. In the mean time we have gotten KEY_SELECTIVE_SCREENSHOT and this has been used for the clipping-tool function under Fn + PrtSc on more traditional ThinkPad keyboards already. Finding a KEY_FOO code for the cloud key is harder looking at the symbol it seems to refer to cloud-storage which made me think of file syncing, or file transfer which has let me to pick KEY_XFER for this. Note this is based on looking at a picture of the adaptive top row in Home mode and has not been tested on an actual adaptive keyboard. Tested-by:

Switch the hotkey keymap handling over to the sparse-keymap helpers, there should be no functional changes from this. Note all the mappings to KEY_UNKNOWN are removed since that is the default behavior of sparse_keymap_report_event() for unknown scancodes. Also drop the big comment about making changes to the keymaps since the contents of that comment are mostly obsolete. Tested-by:

The input core already filters out EV_KEY events for KEY_RESERVED, remove the check for this in tpacpi_input_send_key() and rely on the input core filtering instead. Also change tpacpi_input_send_key() to only report the scancode once instead of reporting it on both press and release. Together these 2 changes make tpacpi_input_send_key() behave the same as sparse_keymap_report_event(). The goal of this patch is to have a separate commit with the slightly different behavior from sparse_keymap_report_event() before switching over to using the sparse-keymap helpers. Tested-by:

Change the default keymap to report the correct keycodes for the volume and brightness keys. Reporting key events for these is already filtered out by the hotkey_reserved_mask which masks these keys out of hotkey_user_mask at initialization time, so there is no need to also map them to KEY_RESERVED. This avoids users, who want these to be reported, having to also remap the keycodes on top of overriding hotkey_user_mask to report these and Linux userspace has already been overriding the KEY_RESERVED mappings with the correct keycodes through udev/hwdb/60-keyboard.hwdb for years now. Also drop hotkey_unmap() it was only used to dynamically map the brightness keys to KEY_RESERVED and after removing that it has no remaining users. Tested-by:

Change the hotkey_reserved_mask initialization to hardcode the list of reserved keys. There are only a few reserved keys and the code to iterate over the keymap will be removed when moving to sparse-keymaps. Note only the 32 original hotkeys are affected by the hotkey_*_mask values: if (i < sizeof(hotkey_reserved_mask)*8) hotkey_reserved_mask |= 1 << i; The (i < sizeof(hotkey_reserved_mask)*8) condition translates to (i < 32) so this code only ever set bits in hotkey_reserved_mask for the 32 original hotkeys. Therefor this patch does not set any bits in hotkey_reserved_mask for the KEY_RESERVED mappings for the adaptive keyboard scancodes. Tested-by:
