mei: add POWERING_DOWN into device state print

2021-12-27T09:30:48Z

The POWERING_DOWN state string was missing from the device states list, add it. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Link: https://lore.kernel.org/r/20211223094705.204624-1-tomas.winkler@intel.com Signed-off-by: Greg Kroah-Hartman

mei: allow clients on bus to communicate in remove callback

2021-02-06T14:48:11Z

Introduce new intermediate state to allow the clients on the bus to communicate with the firmware from the remove handler. This is to enable to perform a clean shutdown.

mei: abstract fw status register read.

2019-11-07T08:35:49Z

This is to allow working with mei devices embedded within another pci device, where mei device is represented as a platform child device and fw status registers are not necessarily resident in the device pci config space.

mei: expose device state in sysfs

2019-04-25T17:33:34Z

Expose mei device state to user-space through sysfs. This gives indication to applications that driver is in transition, usefully mostly to detect link reset state. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: adjust the copyright notice in the files.

2019-03-27T17:07:54Z

Use unified version of the copyright notice in the files Update copyright years according the year the files were touched, except this patch and SPDX conversions. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: convert to SPDX license tags

2019-03-27T17:07:54Z

Replace boiler plate licenses texts with the SPDX license identifiers in the mei files header. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: dma ring: implement rx circular buffer logic

2018-11-26T15:59:48Z

Implement circular buffer protocol over receive dma buffer. Add extension to the mei message header that holds length of the buffer on the dma buffer. Signed-off-by: Tomas Winkler Signed-off-by: Alexander Usyskin Signed-off-by: Greg Kroah-Hartman

mei: limit the number of queued writes

2018-03-14T18:33:13Z

Limit the number of queued writes per client. Writes above this threshold are blocked till place in the transmit queue is available. The limit is configurable via sysfs and defaults to 50. The implementation should provide blocking I/O behavior. Prior to this change one would end up in the hands of OOM.

mei: speed up the power down flow

2017-12-13T13:10:47Z

When mei driver is powering down due to suspend or shutdown it will iterate over the mei client bus and disconnect each client device attached in turn. The power down flow consist of the link rest, which causes all clients get disconnected at once, hence the individual disconnection can be omitted and significantly reduce power down flow.

mei: drop unreachable code in mei_start

2017-06-13T13:46:18Z

Device disabled state is caught inside the retry loop, so there is no need to check it once again afterwards. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman
