jarkko"The Wait for Interrupt instruction (WFI) provides a hint to the implementation that the current hart can be stalled until an interrupt might need servicing. Execution of the WFI instruction can also be used to inform the hardware platform that suitable interrupts should preferentially be routed to this hart."
Any ideas what actuallly happens when WFI is executed? I don't know. For x86 I just find the opcode from Intel SDM, and then I just read the pseudocode. I usually do not even read the prose unless really need to get bottom of it.

jarkkoOr actually I do care in the sense that it is a huge turn back. It is misguided advertisement by definition because a competing app might not have this artificial feature. Some casual users might even think that an app is somehow better because it has the imaginary performance improvement thanks to Rust.

jarkkoI’m wondering why in #OpenSUSE #Tumbleweed zypper si -d needs the source package as -d should tell to get only build dependencies, and not the source package.

Those are my only remaining remarks for v8.
The idea is that HMAC pipe is used for communication derived from null seed (which changes each power cycle). If the integrity is compromised access to the TPM device will be denied.
I still need to figure out the negative testing. This series has been already tested when machine works as expected and the bus is not compromised.
Combined with TPM2 sealed hard drive encryption should be quite reasonable way to secure a system (of course nothing never is perfect).

jonmasters@jonmasters.socialAlastair captures one of the biggest problems with the current RISC-V spec. When I looked into this a while back I was (almost) shocked at the lack of rigor and state of the tooling. I say almost because I expected it, but was still sad. Read his blog.

Incredible research at BlackHat Asia today by Tong Liu and team from the Institute of Information Engineering, Chinese Academy of Sciences (在iie.ac.cn 的电子邮件经过验证)
A dozen+ RCEs on popular LLM framework libraries like LangChain and LlamaIndex - used in lots of chat-assisted apps including GitHub. These guys got a reverse shell in two prompts, and even managed to exploit SetUID for full root on the underlying VM!
