Changes:
- SAM:
- Update DTX driver state after resume.
- Add DTX Documentation, misc. fixes, and cleanup.
- IPTS:
This implements a new and refined UAPI interface that should improve
stability during suspend and move some responsibility into userspace,
making the driver simpler.
It also fixes some sleep issues due to improper shutdown of the device.
Shortlog:
0a4a44c Add missing include
31ae03d Improve error handling of ipts_control_* functions
287dea0 Prevent lockups if stop is called from the receiver thread
b737a9c On remove, wait until CLEAR_MEM_WINDOW returned.
c5b66a5 Add GET_DEVICE_READY ioctl
af0f84a Seperate UAPI initialization and device probing
4ae7674 Patch the MEI bus to allow sending commands on remove
27772bc Just a few refactorings...

Subject: [PATCH] (surface3-oemb) add DMI matches for Surface 3 with broken DMI
|
|
table
|
|
|
|
On some Surface 3, the DMI table gets corrupted for unknown reasons
|
|
and breaks existing DMI matching used for device-specific quirks.
|
|
|
|
This commit adds the (broken) DMI data into dmi_system_id tables used
|
|
for quirks so that each driver can enable quirks even on the affected
|
|
systems.
|
|
|
|
On affected systems, DMI data will look like this:
|
|
$ grep . /sys/devices/virtual/dmi/id/{bios_vendor,board_name,board_vendor,\
|
|
chassis_vendor,product_name,sys_vendor}
|
|
/sys/devices/virtual/dmi/id/bios_vendor:American Megatrends Inc.
|
|
/sys/devices/virtual/dmi/id/board_name:OEMB
|
|
/sys/devices/virtual/dmi/id/board_vendor:OEMB
|
|
/sys/devices/virtual/dmi/id/chassis_vendor:OEMB
|
|
/sys/devices/virtual/dmi/id/product_name:OEMB
|
|
/sys/devices/virtual/dmi/id/sys_vendor:OEMB
|
|
|
|
Expected:
|
|
$ grep . /sys/devices/virtual/dmi/id/{bios_vendor,board_name,board_vendor,\
|
|
chassis_vendor,product_name,sys_vendor}
|
|
/sys/devices/virtual/dmi/id/bios_vendor:American Megatrends Inc.
|
|
/sys/devices/virtual/dmi/id/board_name:Surface 3
|
|
/sys/devices/virtual/dmi/id/board_vendor:Microsoft Corporation
|
|
/sys/devices/virtual/dmi/id/chassis_vendor:Microsoft Corporation
|
|
/sys/devices/virtual/dmi/id/product_name:Surface 3
|
|
/sys/devices/virtual/dmi/id/sys_vendor:Microsoft Corporation
