Forthcoming Trusted Firmware-A 2.2 release

by Bipin Ravi

Hi, This is to notify that we are planning to target the Trusted Firmware-A 2.2 release during the third week of October as part of the regular 6 month cadence. The aim is to consolidate all TF-A work since the 2.1 release. As part of this, a release candidate tag will be created and release activities will commence from Monday October 7th. Essentially we will not merge any major enhancements from this date until the release is made. Please ensure any Pull Requests (PR's) desired to make the 2.2 release are submitted in good time to be complete by Friday October 4th. Any major enhancement PR's still open after that date will not be merged until after the release. Thanks & best regards, [cid:image001.jpg@01D57244.98C07530] Bipin Ravi | Principal Design Engineer Bipin.Ravi(a)arm.com<mailto:Joshua.Sunil@arm.com> | Skype: Bipin.Ravi.ARM Direct: +1-512-225 -1071 | Mobile: +1-214-212-0794 5707 Southwest Parkway, Suite 100, Austin, TX 78735

Re: [TF-A] Defects detected by Coverity Scan Online

by Sandrine Bailleux

Hi, We are going to configure Coverity Scan Online to make it send notifications to this mailing list. This way, everyone subscribed on this mailing list will be aware of newly detected/eliminated defects found by the tool. The report will provide a summary of the findings (their nature, location in the source code). In order to look up the details or to triage them, you will still need to access the database through the web portal on https://scan.coverity.com/projects/arm-software-arm-trusted-firmware . As a reminder, you will need to create an account to view the defects there (it's possible to use your Github account). This is expected to generate a low volume of emails, as we typically do 1 analysis per week day. As a heads up, the web interface mentions that "an authorization confirmation will be sent to each newly provided email address and must be acknowledged before notifications will be sent". In which case, please ignore these emails. Regards, Sandrine

Hi Tristan, Can you please clarify what your exact concern is? Which files and what text exactly? That will help us answer your concern.

Re: [TF-A] SMC to intentionally trigger a panic in TF-A

by Julius Werner

Hi Dan, Whoops, sorry, this fell through the cracks for me since I wasn't on the to: line. Thanks for your response! > OK I can see the use of that, although I'd be a bit concerned about such a thing being available as a general service in case it gets used as an attack vector. For example, a test program could aggressively use this service to try to get the firmware to leak secure world information or something about its behaviour. Yes, of course, we can gate this with a build option so it would only be available where desired. > However, I think there might already be support for what you need. PSCI is part of the standard service and the function SYSTEM_RESET2 allows for both architectural and vendor-specific resets. The latter allows for vendor-specific semantics, which could include crashing the firmware as you suggest. > > Chrome OS could specify what such a vendor-specific reset looks like and each Chromebook's platform PSCI hooks could be implemented accordingly. Right, but defining a separate vendor-specific reset type for each platform is roughly the same as defining a separate SiP SMC for each of them. It's the same problem that the SMC/PSCI spec and the TF repository layout is only designed to deal with generic vs. SoC-vendor-specific differentiation. If the normal world OS needs a feature, we can only make it generic or duplicate it across all vendors running that OS. > Alternatively, this could potentially be defined as an additional architectural reset. This would enable a generic implementation but would require approval/definition by Arm's Architecture team. Like me they might have concerns about this being defined at a generic architectural level. Yes, I think that would be the best option. Could you kick off that process with the Architecture team? Or tell me who I should talk to about this? Thanks, Julius

Re: [TF-A] About next release

by Joanna Farley

Hi Yann, You are quite correct. We will be looking to create a v2.2 tag release sometime early to mid October. You can expect a more formal notification and a request to get any patches submitted in the next week or so. As in previous releases master will be generally locked for a week or so while closedown testing is performed although we will assess incoming patches to see if they can be taken with low risk.

Re: [TF-A] On supporting unmaintained platforms and downstream projects

by Julius Werner

Hi Soby, > Hi Julius, > Apologize for the radio silence as I was on sabbatical. Yes, I agree the > project needs to have a clear policy around platforms. We will get this > started on our end and send a policy proposal for review. No problem, thanks to Sandrine for taking care of it so quickly. Unfortunately we now discovered that we're still stuck on the same issue with MT8173. Could one of you please help getting https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/990/31 landed to fix that too? Thanks, Julius
