Is the FVP accurate in terms of measuring performance of programs? Is it cycle accurate? If I use clock_gettime to measure time taken on applications, is it meaningful? If not, is there an accurate way to measure performance of programs on the FVP?
Hello,
I was trying to configure the MPAM system for cache capacity partitioning utilising the fvp base model. I noticed, reading the comments related to the configuration parameters, that the maximum capacity control is not functional, but, anyway, the…

Greetings,
I would like to enable top-byte ignore support on the FVP. I would be grateful on any guidelines on how to do that. Thank you very much!
Best regards,

If I leave the FVP idle for around 1 hour and come back to it, I find that it freezes and have to stop the simulation and re-run it again. What is the possible reason for this and is there a way to stop that from happening? Thank you for your…
I have installed the Cortex-A5x4 FVP but I cannot find it in the DS-5 debug configuration. How can I run it?
I would like to know how do I attach gdbserver to my ARM Base FVP for debugging. All tutorials online explain using DS-5. I would like to use gdb since I am more comfortable with it. I already enabled networking on my FVP.
Thanks for your help…
Hi,
In the Early Development Blog for the Cortex-M55 (https://community.arm.com/developer/tools-software/tools/b/tools-software-ides-blog/posts/start-early-development-on-arm-cortex-m55-processor), the mention that a run script to execute the FVP is provided…
When I try to start "FVP_MPS2_Cortex-M55" I get the following error:

I'm a student and I'm about to begin the development of a software module to support MPAM on an ARM system.
I was willing to test the software on an fvp platform, but I'm not able to find any reference about the memory address of the MPAM…

I am a PhD student doing research using the ARMv8 hardware features. I have a few questions regarding them. Some of these may seem a bit trivial, but I like to be a bit more thorough and confirm my understanding, and ARM is relatively new to me…
While Arm continue to supply older (Armv7-A based) Fixed Virtual Platforms, the Arm Platforms deliverables no longer provide updated sources, binary artefacts, or instructions for them.
Most of these platforms will actually work with a more recent release…
This article describes how to build and run a minimal ILP32 software stack on Arm's Foundation model and provides an example of the upstream support now available. The instructions were tested on an Ubuntu 16.04 LTS host.

Hi all,
We have created a new forum for any questions or comments regarding virtual platforms based on Arm Fast Models or Arm Cycle Models, including Fixed Virtual Platforms.https://community.arm.com/developer/tools-software/f/simulation-models
I have understood that FVP can be launched using arm development studio (DS-5). But is there any possiblity of launching FVP using Keil MDK?. If yes, it would be helpful to share the process of launching. I am planning to use it for cortex M4

Guys,
I've been working on porting a custom OS (with Networking) onto the Cortex-R52 FVP Model, and so far everything has worked well. We have been able to get the OS ported with the ARM Memory Protection unit. For Networking, we are using the lan…
I am trying to do some PoC on FVP_BaseR_Cortex-R52x1. My code can boot from EL2 and enter to EL1 properly. But when I was trying to access PL011 UART0, I got a DATA Abort. From the Fast Models Reference Manual Version 11.4.2, I found the PL011 UART0…
Hi,I want to use network on FVP, I added "--network=nat" when starting the FVPbut there was not an ip addr when I booted into the kernel, ifconfig shows as below:

I am doing a writel to a PCIe device which is taking around 3msec due to link in low power state.
writel translates to wmb followed by STR asm instruction.
