*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 22 kernel bugs. Fedora 22 has now been rebased to 4.2.3-200.fc22. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 23, and are still experiencing this issue, please change the version to Fedora 23. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** This bug is being closed with INSUFFICIENT_DATA as there has not been a response in over 4 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously. |
Created attachment 1070784 [details] ACPI DSDT table from /sys/firmware/acpi/tables/DSDT My friend's Dell XPS One 2710 (BIOS Revision A12, Bios Build Date 08/27/2013) has lighted control buttons on the lower right of the screen for changing audio volume, screen brightness, video source, and cdrom eject. I verified all tests in single user mode with no other processes grabbing the input device events. I observed problems that are summarized in the following table showing the control, whether or not the control works properly, whether or not the onscreen display works properly, the netlink message, and the input device event: =============================================================================== control | works? | onscreen? | netlink message | event =============================================================================== volume down | no | no | "PNP0C14:00 000000c1 00000000" | (none) volume up | no | no | "PNP0C14:00 000000c0 00000000" | (none) brightness down | yes | yes | (none) | (none) brightness up | yes | yes | (none) | (none) Computer to HDMI | yes | yes | "PNP0C14:00 000000c4 00000000" | (none) HDMI to Computer | yes | yes | "PNP0C14:00 000000c5 00000000" | (none) cdrom eject | no | no | "PNP0C14:00 000000c6 00000000" | (none) =============================================================================== The following key_entry structure array from the driver "linux-4.1.6/drivers/platform/x86/dell-wmi-aio.c" seems to match the volume keys for "c0" and "c1", but they do not work. The other keys do not seem to match. static const struct key_entry dell_wmi_aio_keymap[] = { { KE_KEY, 0xc0, { KEY_VOLUMEUP } }, { KE_KEY, 0xc1, { KEY_VOLUMEDOWN } }, { KE_KEY, 0xe030, { KEY_VOLUMEUP } }, { KE_KEY, 0xe02e, { KEY_VOLUMEDOWN } }, { KE_KEY, 0xe020, { KEY_MUTE } }, { KE_KEY, 0xe027, { KEY_DISPLAYTOGGLE } }, { KE_KEY, 0xe006, { KEY_BRIGHTNESSUP } }, { KE_KEY, 0xe005, { KEY_BRIGHTNESSDOWN } }, { KE_KEY, 0xe00b, { KEY_SWITCHVIDEOMODE } }, { KE_END, 0 } }; The following contains commands and responses for diagnosis.

The resulting disassembler output file may not compile because the disassembler did not know how many arguments to assign to these methods. To specify the tables needed to resolve external control method references, the -e option can be used to specify the filenames. Note: SSDTs can be dynamically loaded at runtime and may or may not be available via the host OS.
