[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] i915 KMS framebuffer issues in 4.2.1/3.7.1.
Good morning, hope the week is going well for everyone. We have been putting 4.2.1 through its paces and noted an issue which is specific to the kernel running on top of the hypervisor. It isn't specific to 4.2.1 but we validated the issue on this platform and on the 3.7.1 kernel for completeness. An attempt to mmap the framebuffer provided by the i915 KMS driver causes a fork() to fail with ENOMEM. Same hardware and kernel on bare-metal works fine. The 'fbterm' utility demonstrates the problem but we can demonstrate on a minimal implemenation of 'mmap + forkpty'. Would be happy to test any patches or ideas if people have a though on the issue. Have a good day. As always, Dr. G.W. Wettstein, Ph.D. Enjellic Systems Development, LLC. 4206 N. 19th Ave. Specializing in information infra-structure Fargo, ND 58102 development.
