Re: BUG: sleeping function called from invalid context

Hi Geoffroy, thanks for your reply! Since the problem never occured when not using XRDP and since I have other more disturbing problems while making my first experiments with ACRN, I will try the same

Re: BUG: sleeping function called from invalid context

Hi Christoph, I’m not an expert on kernel BUGs either, but it does look indeed like it’s related to XRDP (it’s mentioned in the trace so your observation seems very correct). Could you try

Re: ARM Support

Thanks a lot for your reply. It would be awesome to support ARM processors too. Thanks Musa Geoffroy Van Cutsem <geoffroy.vancutsem@...>, 11 Kas 2021 Per, 18:46 tarihinde şunu yazdı:

Re: ARM Support

Hi Musa, There is no support for ARM-based processors at this stage. We would love to have this added to ACRN but nobody has stepped up to this task yet I’m afraid. Thanks, Geoffroy

Hello ACRN community, Is there any support for ARM based processors? Or is there any such support planned? Thanks! Musa

Re: gpio ist not seen in the acrn hypervisor in the whl 10

Hi Geoffory, Actually, we also identified the same problem; namely, the gpio controller is not detected even in the native Linux. We also tried to contact the manufacture, but it isn't easy to

Re: gpio ist not seen in the acrn hypervisor in the whl 10

Hi Jianjie, I do not have any experience with the GPIO subsystem I’m afraid,@Xie, Nanlin, can you ask someone on the engineering team to help look at this? Thanks, Geoffroy
