Hello Kostas,

The Simulated instructions is indeed the number of executed instructions. The result returned by vmirtGetICount should really be considered a cycle count: it includes executed instruc ...

To elaborate on the previous reply - SPSR_hyp is intended to allow Monitor mode (EL3) to inspect and modify the SPSR for Hypervisor mode (EL2). In Hypervisor mode, the same register is directly access ...

Hi Steve,

In answer to your questions:

1. Yes, you can use the physical domains. You should indeed do so if there is no virtual memory involved.

2. There are functions vmirtGetProcessorPhysic ...

PostForum: Ask a Question   Posted: Tue Feb 22, 2011 1:46 am   Subject: arm926ej-s TLB issue
The ARM926 model does support the TLB, so I think this is a platform, instance or TLB mapping issue. A couple of things to try:

1. check that the processor instance has simulated exceptions enabled ...

vmirtAddReadCallBack installs a callback that is executed when the address range is read, not when an instruction is executed in that range. To get called back when an instruction is executed, use som ...

It wasn't quite clear to me from your post, but I assume you are trying to debug the processor model rather than the simulated application - please repost if this isn't the case.

Hi Mahesh,

Hi Archie,

You're correct that the simulator core is single threaded. I agree that it might be useful to report what you describe as "running MIPS" so that the underlying raw simulator pe ...

Hi Archie,

I can give you more information about this, and I also have some questions for you.

Firstly, there is a bug in the version of icmGetProcessorICount in the release that you have - when ...

Hi Bhuvana,

The ARM model on the website is somewhat incomplete - it supports most application code but no coprocessors (so mcr and mrc are unimplemented).

We're currently working on an improved ...
