2025-02-03HID: topre: Fix n-key rollover on Realforce R3S TKL boardsDaniel Brackenbury
Newer model R3* Topre Realforce keyboards share an issue with their older R2 cousins where a report descriptor fixup is needed in order for n-key rollover to work correctly, otherwise only 6-key rollover is available. This patch adds some new hardware IDs for the R3S 87-key keyboard and makes amendments to the existing hid-topre driver in order to change the correct byte in the new model.

2024-08-27HID: change return type of report_fixup() to constThomas Weißschuh
By allowing the drivers to return a "const *" they can constify their static report arrays. This makes it clear to driver authors that the HID core will not modify those reports and they can be reused for multiple devices. Furthermore security is slightly improved as those reports are protected against accidental or malicious modifications.

2023-03-10HID: topre: Add support for 87 keys Realforce R2Alessandro Manca
The tenkeyless version of the Realforce R2 has the same issue of the full size one, the report fixup is needed to make n-key rollover work instead of 6 key rollover Signed-off-by: Alessandro Manca <crizan.git@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2022-09-20hid: topre: Add driver fixing report descriptorHarry Stern
The Topre REALFORCE R2 firmware incorrectly reports that interface descriptor number 1, input report descriptor 2's events are array events rather than variable events. That particular report descriptor is used to report keypresses when there are more than 6 keys held at a time. This bug prevents events from this interface from being registered properly, so only 6 keypresses (from a different interface) can be registered at once, rather than full n-key rollover. This commit fixes the bug by setting the correct value in a report_fixup function. The original bug report can be found here: Link: https://gitlab.freedesktop.org/libinput/libinput/-/issues/804 Thanks to Benjamin Tissoires for diagnosing the issue with the report descriptor.
