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
