PCI spec says that the procedure of sizing a BAR is as follows:
1) disable the decode via command register
2) save the original value of BAR register
3) write all-1 to the BAR register
4) read BAR register back, calculate the size
5) restore the original value to BAR register
6) re-enable the decode via command register
Some driver does not disable the decode of BAR register via the
command register before sizing a BAR. This will lead to a overlay
of the BAR addresses when trying to register the intermediate
BAR address via register_bar. A stateful variable sizing is used
to keep track of such kind of BAR address changes and workaroud
this violation.
Currently this issue is only found when audio device is passed
through to Windows 10 guest. When it is fixed in the Windows
audio driver, this patch should be reverted.
v1 -> v2:
- change the commit message to add the procedure of BAR sizing from

Currently, we use STR_LEN for all checking the size of all the
acrn-dm parameters. But some parameters like kernel boot args
can grow based on different needs. For example, when kata launches
guest VM using acrn, the kernel boot args increases by 256 bytes
(i.e 1024 +256).
Just increasing STR_LEN will unnecessarily increase allocations
for other acrn-dm parameters. So decoupling only boot_args
length and increasing it to 2048.
PS: If other parameters like ramdisk path, kernel path,
elf_path etc. don't need 1024 bytes, we can reduce STR_LEN
to 256 or 512 bytes.

This patch adds support to trigger rescan of virtio-blk device by the
guest VM. This is an alternate to hot-plugging virtio-blk device.
This feature stems from the kata requirement, which hot-plugs container
rootfs after the VM is launched.
As part of virtio-blk rescan,
1. Update the backing file for the virtio-blk device with valid file.
Basically update the empty file (with dummy bctxt) that was passed
during VM launch.
2. Update virtio-blk device configurations for udpated backing file.
3. Update size associated with valid backing file in the config space.
4. Notify guest OS, of the new config change.
5. On this notification, guest will do the following.
(i). Update virtio-blk capacity.
(ii). Revalidate the disk.
(iii). Identify the newly plugged block device.
v5 -> v6:
- Removed use of dummy file and added a new parameter "nodisk"
to virtio-blk which indicates user wants to create a virtio-blk
device with dummy backend.
- Moved vm_monitor_rescan from pci core to virtio-blk as it currently
applies to only virtio-blk.
v4 -> v5:
- Reverted back logic, so that blkrescan is only supported when
VM is launched with empty backend file.
v3 -> v4:
- Close block context before allocating a new one
- Allow backend filepath with additional options to be more generic
- Remove blank lines introduced as part of previous patches.
v2 -> v3:
- Renamed vdev ops vdev_blk rescan to vdev_rescan
- Renamed montior ops virtio_blkrescan_ops to virtio_rescan_ops
- Consolidated virtio-blk configuration specific part into
a separate function
- Removed size requirement in acrnctl command.
v1 -> v2:
- Added more comments in the code.
- Renamed APIs from displug to blkrescan, inline with acrnctl cmd.
- Split the patch into two. This corresponds to changes in acrn-dm.

Device trap has great impact on latency of real time (RT) tasks.
This patch provide a virtio poll mode to avoid trap.
According to the virtio spec, backend devices can declare the
notification is not needed so that frontend will never trap.
This means the backends make commitment to the frontends they have a
poll mechanism which don’t need any frontends notification.
This patch uses a periodic timer to give backends pseudo notifications
so that drive them processing data in their virtqueues. People should
choose a appropriate notification peroid interval to use this poll
mode. Too big interval may cause virtqueue processing latency while
too small interval may cause high SOS CPU usage. The suggested interval
is between 100us to 1ms.
The poll mode is not enabled by default and traditional trap
notification mode will be used. To use poll mode for RT with interval

values. Adjacent `@retval` can be joined into one list by breathe.
v1 -> v2:
* Replace return value descriptions like `negative` and `positive` with
expressions like `<0` and `>0` in `@retval`.
* Keep the list of `@retval` comprehensive, even when there is a `@return` to
generally describe what the return value means.
* Drop duplicated `@return` when it does not give more information than the
`@retval` list.

It is preferred to state the absence of a return value explicitly in the
doxygen-stile comments. Currently there are different styles of doing this,
including:
@return None
@return NULL
@return void
@return N/A
This patch unifies the above with `@return None`.

This patch introduce a new mode of IO request completion, polling mode.
Now, the sketch of ioreq process can be,
A. UOS vcpu0 generate PIO/MMIO ->
B. pcpu1(vcpu0 of UOS) trap into HV ->
C. pcpu1 build ioreq, send IPI and enter idle ->
D.1 pcpu0(vcpu0 of SOS) response IPI,
D.2 pcpu0 handle the ioreq in HV, kernel, DM,
D.3 pcpu0 mark ioreq as complete,
D.4 pcpu0 hypercall to enter HV ->
E.1 pcpu0 send IPI to wake pcpu1 up
E.2 UOS vcpu0 continue running
With this change, it skips D.4, E.1 steps. In step C, pcpu1 will enter a
polling ioreq state idle after send out the IPI.
It can save about ~5000 cpu cycles.
In polling mode, we do the polling in idle instead of pause cpu all the
time. It will consume more power. A better way is to use monitor/mwait
instructions which can put cpu into a sleep state with monitoring a
memory address. Unfortunately, APL has bug with monitor. We can gather
all ioreqs state into one monitorable memory and take advantage of
monitor/mwait for future platform.
The way polling or notification is per VM. We can config VMs in
different mode. By default, IO request completion will use notification
mode for all VMs. We can switch it by Kconfig.

This is the counterpart in DM to the VHM request state update in the
hypervisor. Major changes include:
* Remove accesses to the obsolete 'valid' member.
* Access the 'processed' member using atomic operations.
* Sync the documentation on vhm_request.
In addition, the new state transition also requires a VHM request to be always
handled properly, as there is no 'FAILED' state any more. Instead of crashing
the device model (and thus the UOS as well), the device model should return all
1s or ignore the request when it is to load from or store to an invalid address,
respectively.
Note: there is an issue in vm_system_reset() and vm_suspend_resume() where
completed VHM requests are not properly notified, causing the hypervisor to
complain as it sees uncompleted requests while trying to create a new one. This
issue will be resolved in a separate patch.

Current ring buffer processing logic assumes every transaction
will be submited to physical device before next transaction
coming. So it use two states 0 (free) and 1 (used) to represent
the state of every data block in the ring buffer. With the help
of the two state, the ring buffer could accept and process data
normally.
But this logic is not proper for ISOC transfer, which generally
submits many transactions even none of them arrive the physical
device. So this patch uses three values to represent the state
of data block in the ring buffer:
USB_XFER_BLK_FREE: this block could be filled with new data;
USB_XFER_BLK_HANDLING: this block is submited to physical device
but response from device is still not received;
USB_XFER_BLK_HANDLED: this block has been processed by physical
device.
The new logic will do different things for each state, which will
make the ISOC transfer work successfully.

In this patch, define physical cpu id as "uint16_t" type for all
modules in the hypervisor and change related codes. The valid
range of pcpu_id is 0~65534, INVALID_PCPU_ID is defined to the
invalid pcpu_id for error detection, BROADCAST_PCPU_ID is

The Intel Trace Hub (aka. North Peak, NPK) is a trace aggregator for
Software, Firmware, and Hardware. On the virtualization platform, it
can be used to output the traces from SOS/UOS/Hypervisor/FW together
with unified timestamps.
There are 2 software visible MMIO space in the npk pci device. One is
the CSR which maps the configuration registers, and the other is the
STMR which is organized as many Masters, and used to send the traces.
Each Master has a fixed number of Channels, which is 128 on GP. Each
channel occupies 64B, so the offset of each Master is 8K (64B*128).
Here is the detailed layout of STMR:
M=NPK_SW_MSTR_STP (1024 on GP)
+-------------------+
| m[M],c[C-1] |
Base(M,C-1) +-------------------+
| ... |
+-------------------+
| m[M],c[0] |
Base(M,0) +-------------------+
| ... |
+-------------------+
| m[i+1],c[1] |
Base(i+1,1) +-------------------+
| m[i+1],c[0] |
Base(i+1,0) +-------------------+
| ... |
+-------------------+
| m[i],c[1] |
Base(i,1)=SW_BAR+0x40 +-------------------+
| m[i],c[0] | 64B
Base(i,0)=SW_BAR +-------------------+
i=NPK_SW_MSTR_STRT (256 on GP)
CSR and STMR are treated differently in npk virtualization because:
1. CSR configuration should come from just one OS, instead of each OS.
In our case, it should come from SOS.
2. For performance and timing concern, the traces from each OS should
be written to STMR directly.
Based on these, the npk virtualization is implemented in this way:
1. The physical CSR is owned by SOS, and dm/npk emulates a software
one for the UOS, to keep the npk driver on UOS unchanged. Some CSR
initial values are configured to make the UOS npk driver think it
is working on a real npk. The CSR configuration from UOS is ignored
by dm, and it will not bring any side-effect. Because traces are the
only things needed from UOS, the location to send traces to and the
trace format are not affected by the CSR configuration.
2. Part of the physical STMR will be reserved for the SOS, and the
others will be passed through to the UOS, so that the UOS can write
the traces to the MMIO space directly.
A parameter is needed to indicate the offset and size of the Masters
to pass through to the UOS. For example, "-s 0:2,npk,512/256", there
are 256 Masters from #768 (256+512, #256 is the starting Master for
software tracing) passed through to the UOS.
CSR STMR
SOS: +--------------+ +----------------------------------+
| physical CSR | | Reserved for SOS | |
+--------------+ +----------------------------------+
UOS: +--------------+ +---------------+
| sw CSR by dm | | mapped to UOS |
+--------------+ +---------------+
Here is an overall flow about how it works.
1. System boots up, and the npk driver on SOS is loaded.
2. The dm is launched with parameters to enable npk virtualization.
3. The dm/npk sets up a bar for CSR, and some values are initialized
based on the parameters, for example, the total number of Masters for
the UOS.
4. The dm/npk sets up a bar for STMR, and maps part of the physical
STMR to it with an offset, according to the parameters.
5. The UOS boots up, and the native npk driver on the UOS is loaded.
6. Enable the traces from UOS, and the traces are written directly to
STMR, but not output by npk for now.
7. Enable the npk output on SOS, and now the traces are output by npk
to the selected target.
8. If the memory is the selected target, the traces can be retrieved
from memory on SOS, after stopping the traces.

The VIRTIO_PCI_CAP_PCI_CFG capability creates an alternative access
method to the common configuration, notification, ISR and device-

To access a device region, the driver writes into the capability
structure (ie. within the PCI configuration space) as follows:
- The driver sets the BAR to access by writing to cap.bar
- The driver sets the size of the access by writing 1, 2 or 4 to
cap.length
- The driver sets the offset within the BAR by writing to cap.offset
At that point, pci_cfg_data will provide a window of size cap.length
into the given cap.bar at offset cap.offset.

Full logic to supprot vRPMB:
1. Automatic switch between physical or simulated RPMB.
But hardcode to use simulated one.
2. Parse RPMB cmd to basic APIs to:
2.1 check request frame HMAC with uos vkey
2.2 replace RPMB frame with real values.
3. RPMB partitioning for multiple UOS.
It's hardcoded for coming config file support.
