In ipa_endpoint_stop(), for TX endpoints we set the number of retries

channels, and just break out of the loop
The only reason ipa_endpoint_stop() had a retry loop was that the

attempts. The gsi_channel_stop() call that implements the stop does
its own retry loop, to cover a channel's transition from started to

Create a new helper function that encapsulates enabling or disabling
suspend on an RX endpoint. It returns the previous state of the
endpoint (true means suspend mode was enabled).
Create another function that handles enabling or disabling delay mode
on a TX endpoint. Delay mode does not work
Change ipa_endpoint_init_ctrl() so it returns the previous state
(whether suspend or delay mode was enabled) rather than indicating
whether the request caused a change in state. This makes it easier
to understand what's happening where called.

A "delay mode" feature was put in place to work around a problem
that was observed during development of the upstream IPA driver. It
used TX endpoint "delay mode" in order to prevent transmitting
packets toward the modem before it was ready.
A race condition that would explain the problem has
In several places, a Boolean flag is used in the GSI code to
indicate whether the "doorbell engine" should be enabled or not
when a channel is configured. This is basically done to abstract
this property from the IPA version; the GSI code doesn't otherwise
"know" what the IPA hardware version is.
In gsi_channel_reset(), RX channels are subjected to two consecutive
CHANNEL_RESET commands. This workaround should only be used for IPA
version 3.5.1, and for newer hardware "can lead to unwanted behavior."
Only issue the second CHANNEL_RESET command for legacy hardware.

Some special handling done during channel reset should only be done

Subject: iocost: protect iocg->abs_vdebt with iocg->waitq.lock
abs_vdebt is an atomic_64 which tracks how much over budget a given cgroup
is and controls the activation of use_delay mechanism. Once a cgroup goes
over budget from forced IOs, it has to pay it back with its future budget.

Hi,
This is an RFC patchset for the GRUB introducing the Intel TXT secure launcher.
This is a part of larger work known as the TrenchBoot. Patchset can be split
into two distinct parts:
- 01-12: preparatory patches,
- 13-18: the Intel TXT secure launcher itself.
The initial implementation of
It does not make sense to have separate headers for separate static
functions. Additionally, we have to add some constants with MSR addresses
in subsequent patches. So, make one common place to store them.
