Description: Device DAX is the device-centric analogue of Filesystem
|

DAX (CONFIG_FS_DAX). It allows memory ranges to be
|
||||
allocated and mapped without need of an intervening file
|
||||
system. Device DAX is strict, precise and predictable.
|
||||
Specifically this interface:
|
||||
|
||||
1. Guarantees fault granularity with respect to a given
|
||||
page size (pte, pmd, or pud) set at configuration time.
|
||||
|
||||
2. Enforces deterministic behavior by being strict about
|

what fault scenarios are supported.
|

|
||||
The /sys/class/dax/ interface enumerates all the
|
||||
device-dax instances in the system. The ABI is
|
||||
deprecated and will be removed after 2020. It is
|
||||
replaced with the DAX bus interface /sys/bus/dax/ where

Tolerance level. When a machine check exception occurs for a

non corrected machine check the kernel can take different

actions.
|

|
||||
Since machine check exceptions can happen any time it is
|
||||
sometimes risky for the kernel to kill a process because it
|
||||
defies normal kernel locking rules. The tolerance level
|
||||
configures how hard the kernel tries to recover even at some
|
||||
risk of deadlock. Higher tolerant values trade potentially
|
||||
better uptime with the risk of a crash or even corruption
|
||||
(for tolerant >= 3).
|
||||
|
||||
== ===========================================================
|
||||
0 always panic on uncorrected errors, log corrected errors
|
||||
1 panic or SIGBUS on uncorrected errors, log corrected errors
|

2 SIGBUS or log uncorrected errors, log corrected errors

3 never panic or SIGBUS, log all errors (for testing only)

[RO] The presence of this sub-directory of the

/sys/block/xxx/queue/ directory indicates that the device is

capable of executing requests targeting different sector ranges
|

in parallel. For instance, single LUN multi-actuator hard-disks
|
||||
will have an independent_access_ranges directory if the device
|
||||
correctly advertizes the sector ranges of its actuators.
|
||||
|
||||
The independent_access_ranges directory contains one directory
|
||||
per access range, with each range described using the sector
|
||||
(RO) attribute file to indicate the first sector of the range
|
||||
and the nr_sectors (RO) attribute file to indicate the total
|
||||
number of sectors in the range starting from the first sector of
|
||||
the range. For example, a dual-actuator hard-disk will have the
|
||||
following independent_access_ranges entries.::
|
||||
|
||||
$ tree /sys/block/<disk>/queue/independent_access_ranges/

|

`-- 1
|

|-- nr_sectors
|
||||
`-- sector
|
||||
|
||||
The sector and nr_sectors attributes use 512B sector unit,
|
||||
regardless of the actual block size of the device. Independent
|
||||
access ranges do not overlap and include all sectors within the
|
||||
device capacity. The access ranges are numbered in increasing
|
||||
order of the range start sector, that is, the sector attribute
|

of range 0 always has the value 0.

This sysfs interface allows user to configure features at

firmware as well as the user can configure the parameters of

the features at runtime. The supported features are over

is completely different than the /dev/watchdog as the external

the health of firmware not APU(Linux). Also, the external
|

watchdog is interfaced outside of the zynqmp soc.
|
||||
|
||||
The supported config ids are for the feature configuration is,
|
||||
1. PM_FEATURE_OVERTEMP_STATUS = 1, the user can enable or
|
||||
disable the over temperature feature.
|
||||
2. PM_FEATURE_OVERTEMP_VALUE = 2, the user can configure the
|
||||
over temperature limit in Degree Celsius.
|
||||
3. PM_FEATURE_EXTWDT_STATUS = 3, the user can enable or disable
|
||||
the external watchdog feature.
|
||||
4. PM_FEATURE_EXTWDT_VALUE = 4, the user can configure the
|
||||
external watchdog feature.
|

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

this behavior on one of two ways: When set to 1, complex

merge checks are disabled, but the simple one-shot merges

with the previous I/O request are enabled. When set to 2,

all merge tries are disabled. The default value is 0 -

discard_granularity will be set to match the device's

Devices that support discard functionality may have

discard_max_bytes parameter is set by the device driver
|

to the maximum number of bytes that can be discarded in

a single operation. Discard requests issued to the
|

device must not exceed this limit. A discard_max_bytes

(RO) A region is a contiguous partition of a CXL root decoder

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.

When specified, only a driver with a name matching the value

the device. The override is specified by writing a string to the

This returns the device to standard matching rules binding.

device from its current driver or make any attempt to

matching name is currently loaded in the kernel, the device will

driver binding using a driver_override name such as "none".

no support for parsing delimiters.

The attributes can be displayed to check the stored value.

|

Installing a certificate to enable feature::
|
||||
|
||||
echo "supervisor password" > authentication/Admin/current_password
|
||||
echo "signed certificate" > authentication/Admin/certificate
|
||||
|
||||
Updating the installed certificate::
|
||||
|
||||
echo "signature" > authentication/Admin/signature
|
||||
echo "signed certificate" > authentication/Admin/certificate
|
||||
|
||||
Removing the installed certificate::
|
||||
|
||||
echo "signature" > authentication/Admin/signature
|
||||
echo "" > authentication/Admin/certificate
|
||||
|
||||
Changing a BIOS setting::
|
||||
|
||||
echo "signature" > authentication/Admin/signature
|
||||
echo "save signature" > authentication/Admin/save_signature
|
||||
echo Enable > attribute/PasswordBeep/current_value
|
||||
|
||||
You cannot enable certificate authentication if a supervisor password
|
||||
has not been set.
|
||||
Clearing the certificate results in no bios-admin authentication method

After any of these operations the system must reboot for the changes to
