I haven't started the conversion work for the PI spec, so we can do an errata update promptly if we decide on that soon (say by end of March).

Anyhow... UEFI spec publications and errata are kind of demand-driven - we don't keep a regular schedule so much as make one for an errata or new spec version when a contributor requests that they want one to meet a product deliverable or some equivalent external event that needs to read on an update. Lazy evaluation if you will. Which is to say right now there isn't a PI 1.7A schedule but we can make one 😊 To be sure we have this right is there one specific PI ECR we're talking about or more than one for this?? If we can identify which peg we need put into an errata version to hang these code changes from then I can get with Vincent and we can have the work group crank this handle. That said... The one caveat that applies right this second is that the conversion of the spec sources is in flight. Our tech writer may tell me that there are some related limitations on when exactly we can practically make an update. I don't want to pollute the open lists copied here with that UEFI Forum internal housekeeping but I did want to mention that as a factor by way of not wanting to over-promise an instant fix. -- Cheers, Mark. -----Original Message----- From: p...@uefi.org <p...@uefi.org> On Behalf Of Ard Biesheuvel Sent: Friday, March 6, 2020 2:38 AM To: Gao, Liming <liming....@intel.com>; Stuart Yoder <stuart.yo...@arm.com>; Zimmer, Vincent <vincent.zim...@intel.com>; p...@uefi.org Cc: Ard Biesheuvel <ard.biesheu...@arm.com>; edk2-devel-groups-io <devel@edk2.groups.io>; Kinney, Michael D <michael.d.kin...@intel.com>; Leif Lindholm <leif.lindh...@linaro.org>; Wu, Hao A <hao.a...@intel.com>; Dong, Eric <eric.d...@intel.com>; Ni, Ray <ray...@intel.com>; Achin Gupta <achin.gu...@arm.com>; Yao, Jiewen <jiewen....@intel.com> Subject: [piwg] Re: [PATCH 0/7] New implementation of MM communicate for standalone MM (adding PIWG and some other folks to cc) On Mon, 6 Jan 2020 at 02:16, Gao, Liming <liming....@intel.com> wrote: > > Ard: > The changes are good to me.

Is there any way we can progress with this independently? Or push on with the publication of PI 1.7 errata A ?
