Re: [edk2] [PATCH 1/7] MdeModulePkg PeiCore: Remove the using of PcdPeiCoreMaxPeimPerFv
Good suggestion. It will make the buffer extension log consistent. I will send V2 to cover it with some test.

Reviewed-by: Chasel Chiu -Original Message- From: Zeng, Star Sent: Friday, December 14, 2018 6:29 PM To: edk2-devel@lists.01.org Cc: Zeng, Star ; Wang, Jian J ; Wu, Hao A ; Gao, Liming ; Ni, Ruiyu ; Kinney, Michael D ; Desimone, Nathaniel L ; Chiu, Chasel Subject: [PATCH 1/7] MdeModulePkg PeiCore: Remove the using of PcdPeiCoreMaxPeimPerFv REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1405 Background as below. Problem: As static configuration from the PCDs, the binary PeiCore (for example in FSP binary with dispatch mode) could not predict how many FVs, Files or PPIs for different platforms. Burden: Platform developers need configure the PCDs accordingly for different platforms. To solve the problem and remove the burden, we can update code to remove the using of PcdPeiCoreMaxFvSupported, PcdPeiCoreMaxPeimPerFv and PcdPeiCoreMaxPpiSupported by extending buffer dynamically for FV, File and PPI management. This patch removes the using of PcdPeiCoreMaxPeimPerFv in PeiCore.
