Re: [gem5-dev] Namespace Inconvenience

Hi Daneil, thanks for the heads up. I've seen similar things like that every once in a while in the past and had hoped to some day nail down where the stale files were. It seems to be the param structure definitions for you? I can see how that would happen since those are generated from python,

[gem5-dev] Design doc - Merge gem5’s VPtr and BufferArg classes

One of these types is no longer used since Alpha was deleted, and they're pretty similar to one another but with some complementary capabilities. I put together a design doc which lays out how to merge them, and add some minor new features like teaching the GuestABI to construct them automatically

Re: [gem5-dev] How to get the size in bytes of a guest int or unsigned value to implement a system call?

Hi Ciro. There are some folks from AMD I think who have been doing quite a lot with syscall emulation and should probably chime in too, but here is my understanding. If you're accepting an address, you should use the Addr type. This is sometimes treated specially, and even though it's a 64 bit

[gem5-dev] How to get the size in bytes of a guest int or unsigned value to implement a system call?

I want to implement the simple getcpu syscall. According to man getcpu and kernel source in kernel/sys.c, that function as an argument an unsigned *cpu to which it writes the value. I was looking through the other syscall implementations in syscall_emul.hh but all I've seen so far appear to

[gem5-dev] Namespace Inconvenience

Hello all, I have just merged https://gem5-review.googlesource.com/c/public/gem5/+/24537, which may cause the following inconvenience: In file included from build/ISA/python/_m5/param_BaseCache.cc:4:0:build/ISA/params/BaseCache.hh:66:5: error: 'BasePrefetcher' does not name a type

Re: [gem5-dev] gem5-resources: Feedback appreciated!

Yes, my main point is that hopefully when you run "make ISA=arm64" / or scons it will build at least all single input source files that we have in one go e.g.: main.c -> out/arm64/main.out test2.c -> out/arm64/test2.out for the given ISA, as I did in the mentioned patchset, without me having
