Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
![]() When ECPF eswitch manager is at offloads mode, it monitors functions changed event from host PF side and acts according to the number of VFs enabled/disabled. As ECPF and host PF work in two independent hosts, it's possible that host PF OS reboots but ECPF system is still kept on and continues monitoring events from host PF. When kernel from host PF side is booting, PCI iov driver does sriov_init and compute_max_vf_buses by iterating over all valid num of VFs. This triggers FLR and generates functions changed events, even though host PF HCA is not enabled at this time. However, ECPF is not aware of this information, and still handles these events as usual. ECPF system will see massive number of reps are created, but destroyed immediately once creation finished. To eliminate this noise, a bit is added to host parameter context to indicate host PF is disabled. ECPF will not handle the VF changed event if this bit is set.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
