I have wrote a small Linux Shell command for implementing Interlock Protocol which is known as a cryptographic protocol that resistant to man-in-the-middle attack. Here is the steps of interlock protocol: *(1)* Alice send her public key to Bob *(2)* Bob send his public key to Alice. *(3)* Alice encrypts her message using Bob's public key. Then she sends half of that encrypted message to

...rastructure and I'd like to contribute with a patch to add bundling capabilities to the current post RA scheduler if the LLVM community is interested :-) (May Hexagon need it as well?). It would also be a great opportunity for us to get feedback from the community about this. We have a non-interlocked processor which relies on the post ra scheduler to emit cycle-accurate bundles (valid bundles without incurring in structural hazards). The construction of bundles outside the scope of post RA scheduling will require structural hazard information to work properly for processors without pipeline...

...ove the design. Here's what you can expect in the MachineScheduler: 1. Precise register pressure tracking with back off. I'm in the process of checking in the pieces for this. It should be usable sometime in the next couple of weeks. 2. Division of the target-defined resources into "interlocked" vs. "buffered". The HazardChecker will continue to handle the interlocks for the resources that the hardware handles in order. Buffered resources, which the hardware can handle out of order. These will be considered separately for scheduling priority. We will also make a distinction...

While I had thought I'd tested this before, it looks like this one issue slipped by my original CRC patches. Basically, there seem to be a few rules we need to follow when sending CRC commands to the display controller: * CRCs cannot be both disabled and enabled for a single head in the same flush * If a head with CRC reporting enabled switches from one OR to another, there must be a

...sed most of the postRA list scheduler code and the resource priority queue. Every time it needs to move forward, either because of a res hazard (HazardRec) or an invalid combination of instructions in the current packet (DFA), it closes the current bundle and advances to the next cycle. The non-interlocked nature of our processor forces the bundling logic to live with the scheduling logic. We cannot build bundles without the scoreboard. I also tried to build bundles as a preRA pass in order to reduce the register pressure (so the RA will take full advantage of the vliw architecture). I've ra...

Hey Everyone, I'd like to begin a project to rework the scheduler to address some problems we've discovered on this end. The goal is to get a more configurable/flexible scheduler while simplifying maintenance by separating policy from implementation to get independent and interchangeable parts. This is going to be challenging because we are still stuck on LLVM 2.9. We will be upgrading

Hi, I am working on developing a professional Marketing Materials for my systems. I plan on using a very good(expensive) company to do that so splitting the costs with several people would be nice. Let me know if you are interested on taking part in it. robert -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Martin, > The CPU that I am targeting is VLIW with no hardware interlocking (the next instruction does not wait for the previous to complete). This leads to fairly complex scheduling, but can be generally accommodated well in LLVM. Thanks for sharing your usecase about instruction scheduling, I am learning Instruction Selector by reading ARM and AMDGPU target's source code, then
