The HWT framework provides infrastructure for hardware-assisted tracing. It
collects detailed information about software execution and records it as
"events" in highly compressed format into DRAM. The events cover information
about control flow changes of a program, whether branches taken or not,
exceptions taken, timing information, cycles elapsed and more. This allows
to reconstruct entire program flow of a given application.
This comes with separate machine-dependent tracing backends for trace
collection, trace decoder libraries and an instrumentation tool.

This commit adds a storage driver that supports the Universal Flash
Storage Host Controller Interface (UFSHCI) on FreeBSD.
Universal Flash Storage (UFS) is a flash-based mobile storage device
that replaces eMMC, aiming for high performance with low power. The UFS
Host Controller Interface (UFSHCI) is the host side controller and
connects UFS device to a system bus, such as PCIe.
The code targets the latest standards:
- UFS 4.1: https://www.jedec.org/standards-documents/docs/jesd220g
- UFSHCI 4.1: https://www.jedec.org/standards-documents/docs/jesd223f
The ufshci(4) driver implements controller/device initialization,
interrupt, single-doorbell(SDB) queue based IO requests. Support for
multi-queue (MCQ) IO requests is planned for a later commit.
Implemented features:
- PCIe bus support
- legacy(INTx) Interrupt Handling
- UIC command support
- UTP Transfer Request (UTR) support
- UTP Task Management Request (UTMR) support
- single doorbell queue (SDB) with multiple queue depth
- SCSI command set support
- sysctl
Work in progress:
- multi-Circular Queue (per-CPU IO queues)
- MSI-X interrupt Support
- write booster
- write Protect
- Host Performance Booster (HPB)
- interrupt aggregation
- ARM based system bus support
- ufs-utils port
Tests were performed on QEMU and an Intel-based laptop.
Since QEMU has an emulated UFS device, I tested on QEMU.
How to test on QEMU:
1. Run QEMU
$ qemu-system-x86_64 ... -device ufs -drive file=blk1g.bin,format=raw,if=none,id=luimg -device ufs-lu,drive=luimg,lun=0
2. Loading/unloading the ufshci module on QEMU
$ kldload /usr/obj/usr/src/amd64.amd64/sys/modules/ufshci/ufshci.ko
$ kldunload ufshci
Testing on real hardware:
- Samsung Galaxy Book S (Intel Lakefield) with UFS 3.0
- Lenovo duet 3 11ian8 (Intel N100) with UFS 2.1

Moved handling of debugfs entries to a separate file.
In addition, it will allow to consolidate the addition of
debugfs entries to a single location in the code.
This implementation adds infrastructure to create (and remove)
debugfs entries at two different stages.
- Done when a device is probed, allows to keep debugfs entries
persistent between a transition in device state (up to down or
vice versa).
- Done after the initialization phase, allows to have debugfs
entries that are accessible only when the device is up.
In addition, moved the creation of debugfs entries for configuration
of the newly created function adf_dbgfs_init() and replace symbolic
permissions with octal permissions when creating the debugfs files.
Added sysctl oids storage for proper cleanup on device down.

Build and sysctl configuration modes are introduced for QAT SPR
devices to disable safe dc mode. A new QAT driver build option
‘QAT_DISABLE_SAFE_DC_MODE’ is required to build the QAT driver
with code that allows a request to be sent to FW to override the
‘History Buffer’ mitigation. Default QAT driver builds do not
include this ‘QAT_DISABLE_SAFE_DC_MODE’ build option. Even if the
QAT driver was built with code that allows a request to be sent to
FW to override the ‘History Buffer’ mitigation, the QAT driver must
still be configured using sysctl to request an override of the
‘History Buffer’ mitigation if desired. The default QAT driver
configuration option sysctl dev.qat.X.disable_safe_dc_mode does not
allow override of the mitigation. The new sysctl attribute
disable_safe_dc_mode is to be set to 1 for overriding the history
buffer mitigation. Firmware for qat_4xxx is updated for this change.
If this mode is enabled, decompression throughput increases but may
result in a data leak if num_user_processes is more than 1.
This option is to be enabled only if your system is not prone to
user data leaks.

Following the example of rtw88 and rtw89 only ship iwlwifi firmware
from ports/packages. Users are asked to run fwget(8) to install the
firmware needed for their system or build it from ports
(see also UPDATING).
This is the end of a long story adding wireless support to fwget(8),
migrating the firmware for multiple branches into ports, splitting them
up into flavors, and updating some install media and the installer to
provide firmware.
The overall amount for new firmware amongst all drivers would have
added more than 100M of binary blobs to src.git for the first import,
ignoring future updates which (along with some duplication between
multiple drivers) was considered too much.
While maintenance within the src tree certainly would have been
easier in the longer term this seems to be the better solution and
I would like to thank everyone who helped along the path to get there.
The iwlwififw.4 man page is to stay (for now) and will likely point
at the appropriate firmware package flavor in the future as well
so people may find it easier to transition. In the long term this
information is likely not needed anymore.

This driver originates from OpenBSD and was ported to FreeBSD by Future
Crew LLC who kindly provided a source release.
iwx supports many recent Intel WiFi card and this driver should support running
these cards with legacy, HT and VHT rates. There are some issues remaining in
the port, but at this point wider testing is sought.
To avoid breaking deployed WiFi configurations iwx probes with a lower
priority than iwlwifi. This can be changed by blocking iwlwifi with
devmatch.

On all three platforms supported by vmm, we have mostly duplicated code
to manage guest physical memory regions. Deduplicate much of this code
and move it into sys/dev/vmm/vmm_mem.c.
To avoid exporting struct vm outside of machdep vmm.c, add a new
struct vm_mem to contain the memory segment descriptors, and add a
vm_mem() accessor, akin to vm_vmspace(). This way vmm_mem.c can
implement its routines without needing to see the layout of struct vm.
The handling of the per-VM vmspace is also duplicated but will be moved
to vmm_mem.c in a follow-up patch.
On amd64, move the ppt_is_mmio() check out of vm_mem_allocated() to keep
the code MI, as PPT is only implemented on amd64. There are only a
couple of callers, so this is not unreasonable.
No functional change intended.
