Re: [PATCH 2/9] ArmPlatformPkg/ArmVExpressPkg: CTA15-A7: Allow EDK2_SKIP_PEICORE to be specified at build time

Oh, I don't want to add support ;-) but I was using this patch a long time ago when I was attempting to do such crazy things due to various bugs we found interacting with Boot Monitor, etc... So I ended up keeping this patch, even though it is never used.

[PATCH 1/1] BaseTools: Apply ARM GenFv patch

[RFC] first view: armv7 Linux UEFI runtime services

by Leif Lindholm

Hi all, Following on the previous patch, here is the armv7 UEFI runtime services support, documented on https://wiki.linaro.org/LEG/Engineering/Kernel/UEFI/RuntimeServices (Do note - GRUB boot is currently the only way to actually get the UEFI system table into the kernel.) The patches were based off linux-linaro-tracking, and when I tried building for upstream 3.10-rc6 it failed due to a couple of header file changes. I will address that during cleanup before upstream submission later this week. Oh, and there is an accidental remaining edit of an x86 ifdef in init/main.c. That will be fixed tomorrow. Again, early reviewing would be appreciated. / Leif

[RFC] first view: armv7 Linux early_ioremap

by Leif Lindholm

Hi all, This is my first, monolithic, stab at an early_ioremap for ARMv7 - taken straight from the head of http://git.linaro.org/gitweb?p=people/leiflindholm/linux-uefi-runtime-servi… I'll be cleaning up, splitting up, documenting and see if I can get it working on non-LPAE in time, and then send it upstream later this week. Early reviewing would be much appreciated. / Leif

Re: Possible race condition in multi-core EDK2

by Roy Franz

Hi Oliver, Sorry for the missing information. I am using version 7.1.63 of the A15 fast model. I'm using the ArmVExpress-RTSM-A15_MPCore.dsc dsc file,and building against the linaro-tracking-2013.05 branch of the uefi-next repository. I have been making some changes, mostly debug related. I had made the following changes to the DSC file: gArmPlatformTokenSpaceGuid.PcdCoreCount|1 gArmPlatformTokenSpaceGuid.PcdSendSgiToBringUpSecondaryCores|FALSE This was running fine on a single core until I started removing some debug prints.

[PATCH 0/1] Removing GIC driver from Arndale BSP

by Ryan Harkin

These two patches will remove the GIC driver from the Arndale BSP, instead using the official GIC driver from the upstream tree: [PATCH 1/2] Samsung/Arndale: remove GIC400 driver [PATCH 2/2] ArmPkg/PL390Gic: remove ArmPlatformLib from inf file I've already sent the second patch to Olivier for review, but as far as I can see, ArmPlatformLib is incuded in the PL390 sec lib, but it isn't needed. Including it when booting on Arndale hangs the board. I'm guessing there are two issues: 1) if it isn't needed, we can remove it 2) but it shouldn't crash Arndale if it is included, so Arndale is most likely doing something wrong and we should probably work out what that is. However, the general act of replacing Arndale's clone of the GIC driver seems safe. Arndale appears to have simply cloned an old version of the driver without modification. However, a couple of the bit masks may be different, so perhaps there is an underlying problem that I have not discovered? Hence, a review by a few other people is really important. Regards, Ryan.

Possible race condition in multi-core EDK2

by Roy Franz

I've been working with the DEBUG build of EDK2, and thought I had changed the configuration to be 'proper' for a single core, and it ran fine on a single core simulation. As I started removing debug prints, I started getting simulator seg faults. I confirmed that the difference between running and crashing versions were simply debug prints. Changing the simulation to simulator 2 cores resolved the problem. I suspect that there may be a race condition or some other multi-core detection bug that causes this crash. I don't plan to investigate this further at this point - just wanted to report this as I was surprised to find that a debug print being removed would cause the simulator to crash. Roy
