Re: [TF-A] New Defects reported by Coverity Scan for ARM-software/arm-trusted-firmware

by Sandrine Bailleux

Hello Joanna, Varun, Regarding the idea of looping in Coverity Scan Online in the patch submission process, that is not possible because this free service from Synopsys only allows for a dozen of analyses to be requested per week per open-source project. If we were to request analyses for every patch submission, we would hit the limit very quickly. That is the reason why this is setup to run on the integration branch once per work week day at the moment. I appreciate this is not ideal (as pointed out by both of you) as we get defects reports after patches have been merged but I can't see another way out of this.

cactus and ivy on Tegra194

by Varun Wadekar

Hello, In order to test the SPM dispatcher from TF-A, we plan to enable 'cactus' and 'ivy' on Tegra194 platforms. I was able to muscle my way through all the compilation issues, but the final payload generation part is not that clear. Can someone please help me with the steps to generate the final FIP package with all the payloads - TF-A, Cactus, Ivy? Thanks.

Re: [TF-A] New Defects reported by Coverity Scan for ARM-software/arm-trusted-firmware

by Joanna Farley

Hi Varun, I agree things are less than ideal at the moment. We take advantage as an open source project to use the Synopsys online Coverity service and this points to the master branch (actually currently the mirror on github) which means these coverity tests are ran on changes after they have been submitted. Less than ideal I know but better than not being ran at all. Really we would like these to be ran as part of the OpenCI as part of patch reviews but we are not there yet. Not sure if the Synopsys online Coverity service can be setup to support this via Gerrit reviews or if this will have to be done after patch submittals. If it has to be done after then some clever CI scripting would need to be done to identify where the offending change came from. Would welcome other ideas to make this experience better, but for now this is better than nothing.

[PATCH] Add support for ARMv8.3-SPE

by Wei Li

When ARMv8.3-SPE is implemented, ID_AA64DFR0_EL1.PMSVer is read as 0b0010, update the version check to support ARMv8.3-SPE or higher.

Re: [TF-A] [Hafnium] Debugging page table creation in Hafnium

by Madhukar Pappireddy

Hi Raghu and Andrew, Thanks for the inputs. I have added the mm_vm_dump() call to the mm_init() function but nothing was dumped to uart log. I guess I am missing something trivial. It looks like mm_root_table_count() returns 0. Any suggestions? diff --git a/src/mm.c b/src/mm.c index 2e352e9..7c56a09 100644 --- a/src/mm.c +++ b/src/mm.c @@ -1041,5 +1041,7 @@ bool mm_init(struct mpool *ppool) mm_identity_map(stage1_locked, layout_data_begin(), layout_data_end(), MM_MODE_R | MM_MODE_W, ppool); + mm_vm_dump(&ptable); + return arch_mm_init(ptable.root); } Thanks, Madhukar -----Original Message----- From: Hafnium <hafnium-bounces(a)lists.trustedfirmware.org> On Behalf Of Andrew Walbran via Hafnium Sent: Friday, July 17, 2020 6:10 AM To: Raghu K <raghu.ncstate(a)icloud.com> Cc: hafnium(a)lists.trustedfirmware.org Subject: Re: [Hafnium] Debugging page table creation in Hafnium Yep, mm_vm_dump sounds like what you're looking for. You can add a call where you like and it will go to the log UART.

Re: [TF-A] Pointer Authentication keys

by Soby Mathew

Hi Varun, AIU, Usually 2 keys are used to protect 2 different software contexts for enforcing the security boundary between them. This is the case for kernel and userspace. In TF-A, every BL image is allowed to choose the IA key to use, hence every BL image can have a separate IA key. Each BL image is executing within a single security domain and hence there is less use create a boundary within the BL image by using the 2nd key registers. The Compiler by default selects either IA or IB instruction key register to use by default. It cannot automatically make use of both key registers and it doesn't support the use of DA or DB yet I think. There are some function attributes which allow to use a different key at a function level, but the functions need to be marked out manually. But the requirement for creating the sub-domain within a BL image by specifying a different key for certain functions has not yet been seen AFAIK.

But the current implementation only writes IA key [1]. I would like to understand the thought process behind programming only one key here. AFAIU, we should enable all keys - IA, IB, DA, DB. -Varun [1] https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/…
