Patch merged into coreboot/master: arm64: mmu: Make page table manipulation work across stages
by gerrit＠coreboot.org 11 Nov '15

11 Nov '15

the following patch was just integrated into master: commit fe4cbf1167fcb27ec332a2efe16297705ca07359 Author: Julius Werner <jwerner(a)chromium.org> Date: Wed Oct 7 18:38:24 2015 -0700 arm64: mmu: Make page table manipulation work across stages In order to have a proper runtime-modifyable page table API (e.g. to remap DRAM after it was intialized), we need to remove any external bookkeeping kept in global variables (which do not persist across stages) from the MMU code. This patch implements this in a similar way as it has recently been done for ARM32 (marking free table slots with a special sentinel value in the first PTE that cannot occur as part of a normal page table). Since this requires the page table buffer to be known at compile-time, we have to remove the option of passing it to mmu_init() at runtime (which I already kinda deprecated before). The existing Tegra chipsets that still used it are switched to instead define it in memlayout in a minimally invasive change. This might not be the best way to design this overall (I think we should probably just throw the tables into SRAM like on all other platforms), but I don't have a Tegra system to test so I'd rather keep this change low impact and leave the major redesign for later. Also inlined some single-use one-liner functions in mmu.c that I felt confused things more than they cleared up, and fixed an (apparently harmless?) issue with forgetting to mask out the XN page attribute bit when casting a table descriptor to a pointer. BRANCH=None BUG=None TEST=Compiled Ryu and Smaug. Booted Oak.

Patch merged into coreboot/master: armv7: mmu: Make fine grained page tables work across stages
by gerrit＠coreboot.org 11 Nov '15

11 Nov '15

the following patch was just integrated into master: commit 03a0a6517210b4f53082a499df2a7e743ae7452e Author: Julius Werner <jwerner(a)chromium.org> Date: Tue Sep 29 17:28:15 2015 -0700 armv7: mmu: Make fine grained page tables work across stages Among its other restrictions (which are noted in a comment above the function prototype and stay in place), our makeshift fine-grained page table support for ARM32 has the undocumented feature that it relies on a global bookkeeping variable, causing all sorts of fun surprises when you try to use it from multiple stages during the same boot. This patch redesigns the bookkeeping to stay completely inline in the (persistent) TTB which should resolve the issue. (This had not been a problem on any of our platforms for now... I just noticed this because I was trying to solve the same issue on ARM64.) BRANCH=None BUG=None TEST=Booted veyron_jerry. Mapped a second fine-grained memory range from romstage, confirmed that it finds the next free spot and leaves the bootblock table in place.

Patch set updated for coreboot: amd/amdmct/mct_ddr3: Use training values from previous boot if possible

Use them if the DIMM configuration has not changed since the last boot. The SPD values of all installed DIMMs are hashed and stored in the S3 resume data area of the main system Flash device. If a DIMM is changed the hash will almost certainly change as well, forcing retraining on next boot.

Patch set updated for coreboot: cpu/amd: Add CC6 support
by Timothy Pearson 10 Nov '15

10 Nov '15

Timothy Pearson (tpearson(a)raptorengineeringinc.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/11979 -gerrit commit 40cc6be274abb298e19b4a4aaccb16ff4aaf52fd Author: Timothy Pearson <tpearson(a)raptorengineeringinc.com> Date: Mon Jun 8 19:35:06 2015 -0500 cpu/amd: Add CC6 support This patch adds CC6 power save support to the AMD Family 15h support code. As CC6 is a complex power saving state that relies heavily on CPU, northbridge, and southbridge cooperation, this patch alters significant amounts of code throughout the tree simultaneously. Allowing the CPU to enter CC6 allows the second level of turbo boost to be reached, and also provides significant power savings when the system is idle due to the complete core shutdown.
