Although i agree this is very generic implementation and dependent on mp_init.c so going forward we might feel a feed to make it generic, today we can't do because it has some EDK2 header dependencies which is only available for intel UDK2017 platform (CNL onwards). btw, why you might need to have 2 document, i'm not going to explain how mp_init works on x86 platform, those are already in SDM, this document is to only talk about why we are creating EDK2 interface in coreboot and how intel thinks this can help our partners design. https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 25: closed source in nature > It might be just me, but to me "closed source in nature" sounds like […] i don;t understand what you mean by can't be trusted ? https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 29: get-rid of such close source > If I understand it correctly (please correct me if not), it only […] Yes, you are right https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 35: It’s also possible for coreboot to extend its own : support model and create a sets of APIs which later can be used by FSP to run CPU feature : programming using coreboot published APIs > I don't understand. coreboot already has such an API […] i guess you have missed problem statement, you are referring to proposal and try to understand why i have made this proposal. its clearly mentioned in problem statement why we even need this proposal https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 68: 1. coreboot was using SkipMpInit=1 which will skip entire FSP CPU feature programming. > This is decided per board and not for coreboot in general, AFAICS. not sure what you mean by coreboot? this is a UPD which is intel fsp specific. not sure how this can be in general ? -- To view, visit https://review.coreboot.org/25921 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I5b6096ef31d8a523c00cbad39ab9d4884e735fde Gerrit-Change-Number: 25921 Gerrit-PatchSet: 3 Gerrit-Owner: Subrata Banik <subrata.banik(a)intel.com> Gerrit-Reviewer: Philipp Deppenwiese <zaolin.daisuki(a)gmail.com> Gerrit-Reviewer: Subrata Banik <subrata.banik(a)intel.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-CC: Patrick Georgi <pgeorgi(a)google.com> Gerrit-Comment-Date: Tue, 01 May 2018 11:43:09 +0000 Gerrit-HasComments: Yes Gerrit-HasLabels: No

Change in coreboot[master]: Documentation/Intel: Add MultiProcessorInit documentation

Nico Huber has posted comments on this change. ( https://review.coreboot.org/25921 ) Change subject: Documentation/Intel: Add MultiProcessorInit documentation ...................................................................... Patch Set 3: (5 comments) Thanks for writing this up. The relation to the `SkipMpInit` wasn't clear to me before (I'm not 100% sure yet, but much closer). Please make it clear if you intend to force usage of this interface or if it is optional (for `SkipMpInit=1`). https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… File Documentation/Intel/MultiProcessorInit/MultiProcessorInit.md: https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 7: for Intel 9th Gen (Cannon Lake) and beyond CPUs This is why you are doing it, but it seems to me that the result is 100% generic. Both, coreboot's MP API and EFI_MP_SERVICES_PPI, are SoC and vendor independent. Hence I wouldn't expect this in Documentation/Intel/ and the implementation in cpu/x86/ along- side `mp_init.c`. Maybe split this in two documents, one that states that coreboot implements EFI_MP_SERVICES_PPI APIs and why (foreign code linked with coreboot may rely on it) and one that explains how it's working together with FSP? https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 25: closed source in nature It might be just me, but to me "closed source in nature" sounds like "could not even be trusted if published". https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 29: get-rid of such close source If I understand it correctly (please correct me if not), it only reduces closed-source overhead in case of `SkipMpInit=0`, right? `SkipMpInit=1` will still work and run the least closed-source code? https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 35: It’s also possible for coreboot to extend its own : support model and create a sets of APIs which later can be used by FSP to run CPU feature : programming using coreboot published APIs I don't understand. coreboot already has such an API (include/cpu/x86/mp.h). If it could be used by FSP later, why can't it be used now? https://review.coreboot.org/#/c/25921/3/Documentation/Intel/MultiProcessorI… PS3, Line 68: 1. coreboot was using SkipMpInit=1 which will skip entire FSP CPU feature programming. This is decided per board and not for coreboot in general, AFAICS. -- To view, visit https://review.coreboot.org/25921 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I5b6096ef31d8a523c00cbad39ab9d4884e735fde Gerrit-Change-Number: 25921 Gerrit-PatchSet: 3 Gerrit-Owner: Subrata Banik <subrata.banik(a)intel.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-CC: Patrick Georgi <pgeorgi(a)google.com> Gerrit-Comment-Date: Tue, 01 May 2018 11:26:51 +0000 Gerrit-HasComments: Yes Gerrit-HasLabels: No
