Description:
Some ECs have a feature where they will track transitions of
a hardware-controlled sleep line, such as Intel's SLP_S0 line,
in order to detect cases where a system failed to go into deep
sleep states. The suspend_timeout_ms file controls the amount of
time in milliseconds the EC will wait before declaring a sleep
timeout event and attempting to wake the system.
Supply 0 to use the default value coded into EC firmware. Supply
65535 (EC_HOST_SLEEP_TIMEOUT_INFINITE) to disable the EC sleep
failure detection mechanism. Values in between 0 and 65535
indicate the number of milliseconds the EC should wait after a
sleep transition before declaring a timeout. This includes both
the duration after a sleep command was received but before the
hardware line changed, as well as the duration between when the
hardware line changed and the kernel sent an EC resume command.
Output will be in the format: "%u\n".

What: security/secrets/coco

Contact: Dov Murik <dovmurik@linux.ibm.com>
Description:
Exposes confidential computing (coco) EFI secrets to
userspace via securityfs.
EFI can declare memory area used by confidential computing
platforms (such as AMD SEV and SEV-ES) for secret injection by
the Guest Owner during VM's launch. The secrets are encrypted
by the Guest Owner and decrypted inside the trusted enclave,
and therefore are not readable by the untrusted host.
The efi_secret module exposes the secrets to userspace. Each
secret appears as a file under <securityfs>/secrets/coco,
where the filename is the GUID of the entry in the secrets
table. This module is loaded automatically by the EFI driver
if the EFI secret area is populated.
Two operations are supported for the files: read and unlink.
Reading the file returns the content of secret entry.
Unlinking the file overwrites the secret data with zeroes and
removes the entry from the filesystem. A secret cannot be read
after it has been unlinked.
For example, listing the available secrets::
# modprobe efi_secret
# ls -l /sys/kernel/security/secrets/coco
-r--r----- 1 root root 0 Jun 28 11:54 736870e5-84f0-4973-92ec-06879ce3da0b

-r--r----- 1 root root 0 Jun 28 11:54 e6f5a162-d67f-4750-a67c-5d065f2a9910

# rm /sys/kernel/security/secrets/coco/e6f5a162-d67f-4750-a67c-5d065f2a9910
# ls -l /sys/kernel/security/secrets/coco

Allocations can be mutated as long as the decoder is in the

allocation and then attempts to allocate from the free capacity
in the device partition referred to by 'decoderX.Y/mode'.
Allocate and free requests can only be performed on the highest

allocations are enforced to occur in increasing 'decoderX.Y/id'
order and frees are enforced to occur in decreasing

Date: September 2022
Contact: Alex Williamson <alex.williamson@redhat.com>
Description:
These files provide an interface to PCIe Resizable BAR support.
A file is created for each BAR resource (N) supported by the
PCIe Resizable BAR extended capability of the device. Reading
each file exposes the bitmap of available resource sizes:
# cat resource1_resize
00000000000001c0
The bitmap represents supported resource sizes for the BAR,
where bit0 = 1MB, bit1 = 2MB, bit2 = 4MB, etc. In the above
example the device supports 64MB, 128MB, and 256MB BAR sizes.
When writing the file, the user provides the bit position of
the desired resource size, for example:
# echo 7 > resource1_resize
This indicates to set the size value corresponding to bit 7,
128MB. The resulting size is 2 ^ (bit# + 20). This definition
matches the PCIe specification of this capability.
In order to make use of resource resizing, all PCI drivers must
be unbound from the device and peer devices under the same
parent bridge may need to be soft removed. In the case of
VGA devices, writing a resize value will remove low level
console drivers from the device. Raw users of pci-sysfs
resourceN attributes must be terminated prior to resizing.
Success of the resizing operation is not guaranteed.

PCI Non-Transparent Bridge (NTB) Endpoint Function (EPF) User Guide
===================================================================
:Author: Frank Li <Frank.Li@nxp.com>
This document is a guide to help users use pci-epf-vntb function driver
and ntb_hw_epf host driver for NTB functionality. The list of steps to
be followed in the host side and EP side is given below. For the hardware
configuration and internals of NTB using configurable endpoints see
Documentation/PCI/endpoint/pci-vntb-function.rst
Endpoint Device
===============
Endpoint Controller Devices
---------------------------
To find the list of endpoint controller devices in the system::
# ls /sys/class/pci_epc/
5f010000.pcie_ep
If PCI_ENDPOINT_CONFIGFS is enabled::
# ls /sys/kernel/config/pci_ep/controllers
5f010000.pcie_ep
Endpoint Function Drivers
-------------------------
To find the list of endpoint function drivers in the system::
# ls /sys/bus/pci-epf/drivers
pci_epf_ntb pci_epf_test pci_epf_vntb
If PCI_ENDPOINT_CONFIGFS is enabled::
# ls /sys/kernel/config/pci_ep/functions
pci_epf_ntb pci_epf_test pci_epf_vntb
Creating pci-epf-vntb Device
----------------------------
PCI endpoint function device can be created using the configfs. To create
pci-epf-vntb device, the following commands can be used::
# mount -t configfs none /sys/kernel/config
# cd /sys/kernel/config/pci_ep/
# mkdir functions/pci_epf_vntb/func1
The "mkdir func1" above creates the pci-epf-ntb function device that will
be probed by pci_epf_vntb driver.
The PCI endpoint framework populates the directory with the following
configurable fields::
# ls functions/pci_epf_ntb/func1
baseclass_code deviceid msi_interrupts pci-epf-ntb.0
progif_code secondary subsys_id vendorid
cache_line_size interrupt_pin msix_interrupts primary
revid subclass_code subsys_vendor_id
The PCI endpoint function driver populates these entries with default values
when the device is bound to the driver. The pci-epf-vntb driver populates
vendorid with 0xffff and interrupt_pin with 0x0001::
# cat functions/pci_epf_vntb/func1/vendorid
0xffff
# cat functions/pci_epf_vntb/func1/interrupt_pin
0x0001
Configuring pci-epf-vntb Device
-------------------------------
The user can configure the pci-epf-vntb device using its configfs entry. In order
to change the vendorid and the deviceid, the following
commands can be used::
# echo 0x1957 > functions/pci_epf_vntb/func1/vendorid
# echo 0x0809 > functions/pci_epf_vntb/func1/deviceid
In order to configure NTB specific attributes, a new sub-directory to func1
should be created::
# mkdir functions/pci_epf_vntb/func1/pci_epf_vntb.0/
The NTB function driver will populate this directory with various attributes
that can be configured by the user::
# ls functions/pci_epf_vntb/func1/pci_epf_vntb.0/
db_count mw1 mw2 mw3 mw4 num_mws
spad_count
A sample configuration for NTB function is given below::
# echo 4 > functions/pci_epf_vntb/func1/pci_epf_vntb.0/db_count
# echo 128 > functions/pci_epf_vntb/func1/pci_epf_vntb.0/spad_count
# echo 1 > functions/pci_epf_vntb/func1/pci_epf_vntb.0/num_mws
# echo 0x100000 > functions/pci_epf_vntb/func1/pci_epf_vntb.0/mw1
A sample configuration for virtual NTB driver for virutal PCI bus::
# echo 0x1957 > functions/pci_epf_vntb/func1/pci_epf_vntb.0/vntb_vid
# echo 0x080A > functions/pci_epf_vntb/func1/pci_epf_vntb.0/vntb_pid
# echo 0x10 > functions/pci_epf_vntb/func1/pci_epf_vntb.0/vbus_number
Binding pci-epf-ntb Device to EP Controller
--------------------------------------------
NTB function device should be attached to PCI endpoint controllers
connected to the host.
# ln -s controllers/5f010000.pcie_ep functions/pci-epf-ntb/func1/primary
Once the above step is completed, the PCI endpoint controllers are ready to
establish a link with the host.
Start the Link
--------------
In order for the endpoint device to establish a link with the host, the _start_
field should be populated with '1'. For NTB, both the PCI endpoint controllers
should establish link with the host (imx8 don't need this steps)::
# echo 1 > controllers/5f010000.pcie_ep/start

Tasks Rude RCU
~~~~~~~~~~~~~~
Some forms of tracing need to wait for all preemption-disabled regions
of code running on any online CPU, including those executed when RCU is
not watching. This means that synchronize_rcu() is insufficient, and
Tasks Rude RCU must be used instead. This flavor of RCU does its work by
forcing a workqueue to be scheduled on each online CPU, hence the "Rude"
moniker. And this operation is considered to be quite rude by real-time
workloads that don't want their ``nohz_full`` CPUs receiving IPIs and
by battery-powered systems that don't want their idle CPUs to be awakened.
The tasks-rude-RCU API is also reader-marking-free and thus quite compact,
consisting of call_rcu_tasks_rude(), synchronize_rcu_tasks_rude(),
and rcu_barrier_tasks_rude().
Tasks Trace RCU
~~~~~~~~~~~~~~~
Some forms of tracing need to sleep in readers, but cannot tolerate
SRCU's read-side overhead, which includes a full memory barrier in both
srcu_read_lock() and srcu_read_unlock(). This need is handled by a
Tasks Trace RCU that uses scheduler locking and IPIs to synchronize with
readers. Real-time systems that cannot tolerate IPIs may build their
kernels with ``CONFIG_TASKS_TRACE_RCU_READ_MB=y``, which avoids the IPIs at
the expense of adding full memory barriers to the read-side primitives.
The tasks-trace-RCU API is also reasonably compact,
consisting of rcu_read_lock_trace(), rcu_read_unlock_trace(),
rcu_read_lock_trace_held(), call_rcu_tasks_trace(),
synchronize_rcu_tasks_trace(), and rcu_barrier_tasks_trace().
