[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] [xen master] remove unmodified_drivers directory
commit cac57fda01d25c079458a146eefd267e3e72e7fc
Author: Juergen Gross <jgross@xxxxxxxx>
AuthorDate: Tue Jan 14 13:34:45 2020 +0100

CommitDate: Wed Jan 15 15:22:28 2020 +0000
remove unmodified_drivers directory
Having Linux kernel drivers for 2.6 based kernels in the Xen tree is
not really needed any longer. So remove them from the tree.
In case anyone wants to look at them they are still available in
older branches.

-These drivers provide paravirtualised drivers for pre-PVops Linux
-kernels which have the classic-Xen patches applied. They do not work
-with kernels which are not patched with the classic-Xen patches. In
-particular this includes all PVops kernels.
-
-For 2.6.36 and newer you should use the "PVHVM" functionality which is
-available in the mainline kernel.
-
-To build do one of:
-
- ./mkbuildtree [<arch>]
- NB. You can override paths to Xen sources and a (stub) XenLinux
- build tree via the XEN and XL environment variable.
-
-- or -
- make -C /path/to/kernel/build M=$PWD modules
- NB. This is your native kernel build tree (or a distro provided
- stub), not the XenLinux sources referred to in step 1.
- NB. If you are cross compiling, you need to set ARCH and
- CROSS_COMPILE too.
-
-You get four modules, xen-platform-pci.ko, xen-vbd.ko, xen-vnif.ko and
-xen-balloon.ko. Load xen-platform-pci first, and then
-whichever of xen-vbd, xen-vnif and xen-balloon.ko you happen to need.
