Hello Stefano, Thanks for the clarification. My company uses yocto for image generation. What kind of information do you need to consult me in this case ? Maybe modules sizes/addresses which were mentioned by @Julien Grall ? Regards, Oleg вт, 18 апр. 2023 г. в 20:44, Stefano Stabellini : > On

Hi Michal, I corrected xen's command line. Now it is xen,xen-bootargs = "console=dtuart dtuart=serial0 dom0_mem=1600M dom0_max_vcpus=2 dom0_vcpus_pin bootscrub=0 vwfi=native sched=null timer_slop=0 way_size=65536 xen_colors=0-3 dom0_colors=4-7"; Unfortunately the result was the same. (XEN) - Do

Hello Michal, Yes, I use yocto. Yesterday all day long I tried to follow your suggestions. I faced a problem. Manually in the xen config build file I pasted the strings: CONFIG_EARLY_PRINTK CONFIG_EARLY_PRINTK_ZYNQMP CONFIG_EARLY_UART_CHOICE_CADENCE Host hangs in build time. Maybe I did not set

Hello Michal, I was not able to enable earlyprintk in the xen for now. I decided to choose another way. This is a xen's command line that I found out completely. (XEN) console=dtuart dtuart=serial0 dom0_mem=1600M dom0_max_vcpus=2 dom0_vcpus_pin bootscrub=0 vwfi=native sched=null timer_slop=0

Hello, Thanks guys. I found out where the problem was. Now dom0 booted more. But I have a new one. This is a kernel panic during Dom0 loading. Maybe someone is able to suggest something ? Regards, O. [3.771362] sfp_register_bus: upstream ops attach [3.776119] sfp_register_bus: Bus regist

Hi Stefano, Thank you. If I build xen without colors support there is not this error. All the domains are booted well. Hense it can not be a hardware issue. This panic arrived during unpacking the rootfs. Here I attached the boot log xen/Dom0 without color. A highlighted strings printed exactly af

This is interesting. Are you using Xilinx hardware by any chance? If so, which board? Are you using ImageBuilder to generate your boot.scr boot script? If so, could you please post your ImageBuilder config file? If not, can you post the source of your uboot boot script? SErrors are supposed to be

Re: xen cache colors in ARM

I am familiar with the zcu102 but I don't know how you could possibly generate a SError. I suggest to try to use ImageBuilder [1] to generate the boot configuration as a test because that is known to work well for zcu102. [1] https://gitlab.com/xen-project/imagebuilder On Thu, 27 Apr 2023, Oleg

Re: xen cache colors in ARM

We test Xen Cache Coloring regularly on zcu102. Every Petalinux release (twice a year) is tested with cache coloring enabled. The last Petalinux release is 2023.1 and the kernel used is this: https://github.com/Xilinx/linux-xlnx/tree/xlnx_rebase_v6.1_LTS On Tue, 9 May 2023, Oleg Nikitenko wrote:
