Have a look if you can get that file, otherwise I will try to update this ticket once it's created: - -(Error ID: OOPS-65553b72bc14be693eb1e37814ff9267) - -Yeah, the page fails uploading the code dump file. Actually it seems to upload the whole file but then it shows a "Timeout error" error. Anyway, let me know if you need that file and if so how can I send it to you. - -What's happening here is that the memory range you're asking to dump (physaddrs 0 to 0x3fffffff) includes a lot of devices, including the interrupt controller, which is at 0x1e000000. There's a longstanding bug in the GIC code where it will crash if you try to access its per-CPU register bank from some context that isn't a guest CPU (including the monitor or the QEMU gdb stub), because it doesn't know which CPU's version of the registers you wanted. That's what you've run into here. - -However, I suspect you didn't really want to try to take a memory dump of a pile of devices. The RAM in the vexpress-a9 board starts at 0x60000000, so if you wanted the RAM then try - pmemsave 0x60000000 0x9fffffff memory.dmp - - -LP:1602247 is the bug for the similar issue when using the gdb stub. - - -The QEMU project is currently moving its bug tracking to another system. -For this we need to know which bugs are still valid and which could be -closed already. Thus we are setting the bug state to "Incomplete" now. - -If the bug has already been fixed in the latest upstream version of QEMU, -then please close this ticket as "Fix released". - -If it is not fixed yet and you think that this bug report here is still -valid, then you have two options: - -1) If you already have an account on gitlab.com, please open a new ticket -for this problem in our new tracker here: - - https://gitlab.com/qemu-project/qemu/-/issues - -and then close this ticket here on Launchpad (or let it expire auto- -matically after 60 days). Please mention the URL of this bug ticket on -Launchpad in the new ticket on GitLab. - -2) If you don't have an account on gitlab.com and don't intend to get -one, but still would like to keep this ticket opened, then please switch -the state back to "New" or "Confirmed" within the next 60 days (other- -wise it will get closed as "Expired"). We will then eventually migrate -the ticket automatically to the new system (but you won't be the reporter -of the bug in the new system and thus you won't get notified on changes -anymore). - -Thank you and sorry for the inconvenience. - - -Still valid. - - - -This is an automated cleanup. This bug report has been moved to QEMU's -new bug tracker on gitlab.com and thus gets marked as 'expired' now. -Please continue with the discussion here: - - https://gitlab.com/qemu-project/qemu/-/issues/247 - - |
