This patchset provides a means by which hardware information about the
underlying PCI device can be passed up to userspace (ie, QEMU) so that
this hardware information can be used rather than previously hard-coded
assumptions. A new VFIO region type is defined which holds this
information.
A form
We define a new device region in vfio.h to be able to get the ZPCI CLP
information by reading this region from userspace.
We create a new file, vfio_zdev.h to define the structure of the new
region defined in vfio.h

Define a new configuration entry VFIO_PCI_ZDEV for VFIO/PCI.
When this s390-only feature is configured we initialize a new device
region, VFIO_REGION_SUBTYPE_IBM_ZPCI_CLP, to hold information provided
by the underlying hardware.
This patch is based on work previously done by Pierre Morel.

Add support to discover and enumerate CPUs in Intel hybrid parts. A hybrid

When Linux runs on Intel hybrid parts (i.e., having more than one type of
CPU in the same package), subsystems that deal with specific CPU features
may need to know the type of CPU in which they run. Instead of having each
subsystem to inspect CPUID leaves on its own, add a new member to

In hybrid parts, each type of core reports different types of machine check
errors as the machine check error blocks are tied to different parts of the
hardware. Furthermore, errors may be different across micro-architecture
versions. Thus, in order to decode errors, userspace tools need to know th

Yes, basically usage of managed affinity caused people to report
regressions not being able to change irq affinity from procfs.

Add initial version of Broadcom VK driver to enumerate PCI device IDs
of Valkyrie and Viper device IDs.
VK based cards provide real-time high performance, high throughput,
low latency offload compute engine operations.
They are used for multiple parallel offload tasks as:
audio, video and image pr
This patch series drops previous patches in [1]

Remaining patches are contained in this series to add Broadcom VK driver.

Add misc device base support to create and remove devnode.
Additional misc functions for open/read/write/release/ioctl/sysfs, etc
will be added in follow on commits to allow for individual review.

Add support to load and boot images on card automatically.
The kernel module parameter auto_load can be passed in as false to disable
such support on probe.
As well, nr_scratch_pages can be specified to allocate more or less scratch
memory on init as needed for desired card operation.
Co-developed
Add user space api for bcm-vk driver.
Provide ioctl api to load images and issue reset command to card.
FW status registers in PCI BAR space also defined as part
of API so that user space is able to interpret these memory locations
as needed via direct PCIe access.

Add support to get card_info (details about card),
peerlog_info (to get details of peerlog on card),
and proc_mon_info (process monitoring on card).
This info is used for collection of logs via direct
read of BAR space and by sysfs access (in a follow on commit).

Pass down an interrupt to card in case of panic or reboot so
that card can take appropriate action to perform a clean reset.
Uses kernel notifier block either directly (register on panic list),
or implicitly (add shutdown method for PCI device).

Add open/release to replace private data with context for other methods
to use. Reason for the context is because it is allowed for multiple
sessions to open sysfs. For each file open, when upper layer queries the
response, only those that are tied to a specified open should be returned.

Add reset support via ioctl.
Kill user processes that are open when VK card is reset.
If a particular PID has issued the reset request do not kill that process
as it issued the ioctl.
