hw/cxl/cxl-mailbox-utils: Add device DDR5 ECS control feature

CXL spec 3.1 section 8.2.9.9.11.2 describes the DDR5 Error Check Scrub (ECS)
control feature.

The Error Check Scrub (ECS) is a feature defined in JEDEC DDR5 SDRAM
Specification (JESD79-5) and allows the DRAM to internally read, correct
single-bit errors, and write back corrected data bits to the DRAM array
while providing transparency to error counts. The ECS control feature
allows the request to configure ECS input configurations during system
boot or at run-time.

The ECS control allows the requester to change the log entry type, the ECS
threshold count provided that the request is within the definition
specified in DDR5 mode registers, change mode between codeword mode and
row count mode, and reset the ECS counter.

hw/cxl/cxl-mailbox-utils: Add device patrol scrub control feature

CXL spec 3.1 section 8.2.9.9.11.1 describes the device patrol scrub control
feature. The device patrol scrub proactively locates and makes corrections
to errors in regular cycle. The patrol scrub control allows the request to
configure patrol scrub input configurations.

The patrol scrub control allows the requester to specify the number of
hours for which the patrol scrub cycles must be completed, provided that
the requested number is not less than the minimum number of hours for the
patrol scrub cycle that the device is capable of. In addition, the patrol
scrub controls allow the host to disable and enable the feature in case
disabling of the feature is needed for other purposes such as
performance-aware operations which require the background operations to be
turned off.

Introduce cxl_dev_media_disabled() to check if the media is disabled and
replace sanitize_running() with it.

Make sure that the media has been correctly disabled during sanitation
by adding an assert to __toggle_media(). Now, enabling when already
enabled or vice versa results in an assert() failure.

hw/mem/cxl_type3: Add DPA range validation for accesses to DC regions

All DPA ranges in the DC regions are invalid to access until an extent
covering the range has been successfully accepted by the host. A bitmap
is added to each region to record whether a DC block in the region has
been backed by a DC extent. Each bit in the bitmap represents a DC block.
When a DC extent is accepted, all the bits representing the blocks in the
extent are set, which will be cleared when the extent is released.

hw/cxl/events: Add qmp interfaces to add/release dynamic capacity extents

To simulate FM functionalities for initiating Dynamic Capacity Add
(Opcode 5604h) and Dynamic Capacity Release (Opcode 5605h) as in CXL spec
r3.1 7.6.7.6.5 and 7.6.7.6.6, we implemented two QMP interfaces to issue
add/release dynamic capacity extents requests.

With the change, we allow to release an extent only when its DPA range
is contained by a single accepted extent in the device. That is to say,
extent superset release is not supported yet.

1. Add dynamic capacity extents:

For example, the command to add two continuous extents (each 128MiB long)
to region 0 (starting at DPA offset 0) looks like below:

{ "execute": "qmp_capabilities" }

{ "execute": "cxl-add-dynamic-capacity",
"arguments": {
"path": "/machine/peripheral/cxl-dcd0",
"host-id": 0,
"selection-policy": "prescriptive",
"region": 0,
"extents": [
{
"offset": 0,
"len": 134217728
},
{
"offset": 134217728,
"len": 134217728
}
]
}
}

2. Release dynamic capacity extents:

For example, the command to release an extent of size 128MiB from region 0
(DPA offset 128MiB) looks like below:

{ "execute": "cxl-release-dynamic-capacity",
"arguments": {
"path": "/machine/peripheral/cxl-dcd0",
"host-id": 0,
"removal-policy":"prescriptive",
"region": 0,
"extents": [
{
"offset": 134217728,
"len": 134217728
}
]
}
}

Per CXL spec 3.1, two mailbox commands are implemented:
Add Dynamic Capacity Response (Opcode 4802h) 8.2.9.9.9.3, and
Release Dynamic Capacity (Opcode 4803h) 8.2.9.9.9.4.

For the process of the above two commands, we use two-pass approach.
Pass 1: Check whether the input payload is valid or not; if not, skip
Pass 2 and return mailbox process error.
Pass 2: Do the real work--add or release extents, respectively.

hw/mem/cxl_type3: Add host backend and address space handling for DC regions

Add (file/memory backed) host backend for DCD. All the dynamic capacity
regions will share a single, large enough host backend. Set up address
space for DC regions to support read/write operations to dynamic capacity
for DCD.

With the change, the following support is added:
1. Add a new property to type3 device "volatile-dc-memdev" to point to host
memory backend for dynamic capacity. Currently, all DC regions share one
host backend;
2. Add namespace for dynamic capacity for read/write support;
3. Create cdat entries for each dynamic capacity region.

hw/cxl/device: read from register values in mdev_reg_read()

In the current mdev_reg_read() implementation, it consistently returns
that the Media Status is Ready (01b). This was fine until commit
25a52959f99d ("hw/cxl: Add support for device sanitation") because the
media was presumed to be ready.

However, as per the CXL 3.0 spec "8.2.9.8.5.1 Sanitize (Opcode 4400h)",
during sanitation, the Media State should be set to Disabled (11b). The
mentioned commit correctly sets it to Disabled, but mdev_reg_read()
still returns Media Status as Ready.

To address this, update mdev_reg_read() to read register values instead
of returning dummy values.

Note that __toggle_media() managed to not only write something
that no one read, it did it to the wrong register storage and
so changed the reported mailbox size which was definitely not
the intent. That gets fixed as a side effect of allocating
separate state storage for this register.
