Some targets like "hppa" already implement this fix but others -don't. - -To solve the root cause of this problem, the linux-user/mmap.c should -be fixed to do all the invalidations required. By doing so, up to 6.93% -performance improvements will be achieved. - -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 older bugs 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" within the next 60 days (otherwise it will get -closed as "Expired"). We will then eventually migrate the ticket auto- -matically to the new system. - -Thank you and sorry for the inconvenience. - - -[Expired for QEMU because there has been no activity for 60 days.] - |
