Thanks for your feedback for this and my previous email. They are really useful. Yes of course, I guess I misunderstood the original series and thought there is another improvement for the APIC. > > > + - Improved support for CET Indirect Branch Tracking on x86. > > + - Improved mwait-idle support for SPR and ADL on x86. > > SPR and ADL support is new in the driver, not improved. I will correct this in V2. Another question for adding another entry for x86 that worth to brag about a little bit: I did another dig into patchwork and found that this [1] might be a good candidate. IIUC __ro_after_init is a good feature that both x86 and Arm have leveraged in different level today, so probably the __ro_after_init might worth an entry in CHANGELOG. However I saw your comments in [1] so I am not really sure if you are happy with that, maybe we need to change the wording a little bit to remove your concern? Would you mind sharing some thoughts? Thanks! [1] https://patchwork.kernel.org/project/xen-devel/patch/20220309123936.16991-3-andrew.cooper3@citrix.com/ Kind regards, Henry > > Jan

Would you mind sharing some thoughts? My view hasn't changed, but if Andrew and Roger think this should be mentioned, then I'm not going to stand in the way.

Hi Oleksandr, (+ Arm maintainers for a question) Please see below inline comments (I somehow cannot reply as plain text for this email). + - Add support for VirtIO toolstack on Arm. I would clarify that only virtio-mmio is supported on Arm. (Henry): Sure, will clarify that. + - Allow setting the number of CPUs to activate at runtime from command line + option on Arm. + - Improved toolstack build system. + - Add Xue - console over USB 3 Debug Capability. I would probably also add the following: - Add Renesas R-Car Gen4 IPMMU-VMSA support (Arm) (Henry): If something from a specific vendor needs to be included, I wonder if “add i.MX lpuart and i.MX8QM initial support” also qualify. I will let Arm maintainers to do the final call here. Hope you would be fine with that. - grant-table support on Arm was improved and hardened by implementing “simplified M2P-like approach for the xenheap pages” (Henry): Sure, I will add this. Kind regards, Henry

Hope you would be fine with that. Yes I think that's fine to add things from a specific vendor, including i.MX related stuff
