The patch series provides dynamic capacity device (DCD) emulation in Qemu.
More specifically, it provides the following functionalities:
1. Extended type3 memory device to support DC regions and extents.
2. Implemented DCD related mailbox command support in CXL r3.0: 8.2.9.8.9.
3. ADD QMP interfaces for adding and releasing DC extents to simulate FM
functions for DCD described in cxl r3.0: 7.6.7.6.5 and 7.6.7.6.6.
4. Add new ct3d properties for DCD devices (host backend, number of dc
regions, etc.)
5. Add read/write support from/to DC regions of the device.
6. Add mechanism to validate accessed to DC region address space.
A more detailed description can be found from the previously posted RFC[1].
Compared to the previously posted RFC[1], following changes have been made:
1. Rebased the code on top of Jonathan's branch
https://gitlab.com/jic23/qemu/-/tree/cxl-2023-05-25.
2. Extracted the rename of mem_size to a separated patch.(Jonathan)
3. Reordered the patch series to improve its readability.(Jonathan)
4. Split the validation of accesses to DC region address space as a separate
patch.
5. Redesigned the QMP interfaces for adding and releasing DC extents to make
them easier to understand and act like existing QMP interfaces (like the
interface for cxl-inject-uncorrectable-errors). (Jonathan)
6. Updated dvsec range register setting to support DCD devices without static
capacity.
7. Fixed other issues mentioned in the comments (Jonathan&Nathan Fontenot).
8. Fixed the format issues and checked with checkpatch.pl under qemu code dir.
The code is tested with the DCD patch series at the kernel side[2]. The test
is similar to those mentioned in the cover letter of [1].

I don't the patches on the list.

Something odd going on...
They are in https://lists.nongnu.org/archive/html/qemu-devel/2023-07/msg04105.html
though threading is broken.
Also seems to have made it to qemu-devel on lore
https://lore.kernel.org/all/SG2PR06MB3397F3E74A083607F7492FA4B23EA@SG2PR06MB3397.apcprd06.prod.outlook.com/
Might be a backlog somewhere that will take a while to drain...
Fan, perhaps just resend the lot and make sure the threading works so we can find them more easily.
