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:

Hans de Goede authored
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:

Do not send ACPI netlink events for unknown hotkeys, to avoid userspace starting to rely on them. Instead these should be added to the keymap to send evdev events. This should not cause a behavior change for existing laptop models since all currently known 0x1xxx events have a mapping. In hindsight the ACPI netlink events should have been suppressed for the adaptive keyboard and extended hotkeys events too. But the kernel has been sending ACPI netlink events for those for a long time now, so we cannot just stop sending them without potentially causing issues for existing users who may depend on these.

All callers of tpacpi_input_send_key() first call tpacpi_driver_event(), move the tpacpi_driver_event() inside tpacpi_input_send_key() to avoid code duplication. For the original hotkey codes 0x1001 - 0x1020 tpacpi_driver_event() never returns true. So the added "return true;" inside tpacpi_input_send_key() never happens when called from tpacpi_hotkey_send_key() so behavior does not change. Tested-by:

Call tpacpi_driver_event() at the top of hotkey_notify_hotkey() for all (orig / adaptive / extended) hotkey types, rather then having the orig code path call tpacpi_input_send_key_masked() which calls it through hotkey_driver_event() and having the adaptive / extended helpers call it separately.

Factor out the adaptive kbd non hotkey event handling into adaptive_keyboard_change_row() and adaptive_keyboard_s_quickview_row() helpers and move the handling of TP_HKEY_EV_DFR_CHANGE_ROW and TP_HKEY_EV_DFR_S_QUICKVIEW_ROW to tpacpi_driver_event(). This groups all the handling of hotkey events which do not emit a key press event together in tpacpi_driver_event(). This also drops the returning of false as known-event value when adaptive_keyboard_get_mode() / adaptive_keyboard_set_mode() fail. These functions already log an error on failure, returning false just leads to an extra messgae being logged about the hkey event being unknown, which is wrong as the event is not unknown.

Hans de Goede authored
tpacpi_driver_event() already only responds to hkey events which it knows about. Make it return a bool and return true when it has handled the event. This avoids the need to list TP_HKEY_EV_foo values to which it responds both in its caller and in the function itself. Instead callers can now call it unconditionally and check the return value.

Modify hotkey_notify_hotkey() and it helpers to mostly directly operate on hkey codes (TP_HKEY_EV_* returned by "MHKP") instead of on the 0 - TPACPI_HOTKEY_MAP_LEN scancodes used for scancode -> keycode translation. Keeping things in the hkey format as long a possible is a bit cleaner and this patch prepares things for moving to sparse-keymaps. Tested-by:

Hans de Goede authored
Use tpacpi_input_send_key() in adaptive_keyboard_hotkey_notify_hotkey() instead of re-implementing it there. Note this change will also result in a behavioral change, key presses on the adaptive keyboard will now also send a EV_MSC event with the scancode, just like all other hotkey presses already do. This is not a bug but a feature. Reviewed-by:

Hans de Goede authored
hotkey_exit() already takes the mutex around the hotkey_poll_stop_sync() call, but not around the other calls. commit 38831eaf ("platform/x86: thinkpad_acpi: use lockdep annotations") has added lockdep_assert_held() checks to various hotkey functions. These lockdep_assert_held() checks fail causing WARN() backtraces in dmesg due to missing locking in hotkey_exit(), fix this.

One of the stages in IFS image loading process involves loading individual chunks (test patterns) from test image file to secure memory. Driver issues a WRMSR(MSR_AUTHENTICATE_AND_COPY_CHUNK) operation to do this. This operation can take up to 5 msec, and if an interrupt occurs in between, the AUTH_AND_COPY_CHUNK u-code implementation aborts the operation. Interrupt sources such as NMI or SMI are handled by retrying. Regular interrupts may occur frequently enough to prevent this operation from ever completing. Disable irq on local cpu around the aforementioned WRMSR to allow the operation to complete. Signed-off-by:

"Scan controller error" means that scan hardware encountered an error prior to doing an actual test on the target CPU. It does not mean that there is an actual cpu/core failure. "scan signature failure" indicates that the test result on the target core did not match the expected value and should be treated as a cpu failure. Current driver classifies both these scenarios as failures. Modify the driver to classify this situation with a more appropriate "untested" status instead of "fail" status. Signed-off-by:
