This reverts commit 7beee5f3eb.
While they repositories of those drivers state that the in kernel one
should be used, as they are newer, it seems they do not provide the
same functionallity. So revert to the out of tree drivers for now.

KERNEL SOURCE: ============== We currently use the Ubuntu kernel sources, available from: http://kernel.ubuntu.com/git/ubuntu/ubuntu-xenial.git/ Ubuntu will maintain those kernels till: https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Additional/Updated Modules: --------------------------- - include latest e1000e driver from intel/sourceforge - include latest ixgbe driver from intel/sourceforge - include latest igb driver from intel/sourceforge # Note: hpsa does not compile with kernel 3.19.8 #- include latest HPSA driver (HP Smart Array) # # * http://sourceforge.net/projects/cciss/ - include native OpenZFS filesystem kernel modules for Linux * https://github.com/zfsonlinux/ For licensing questions, see: http://open-zfs.org/wiki/Talk:FAQ - include latest DRBD 9 driver, see http://drbd.linbit.com/home/what-is-drbd/ FIRMWARE: ========= We create our own firmware package, which includes the firmware for all proxmox-ve kernels. So far this include pve-kernel-2.6.18 pve-kernel-2.6.24 pve-kernel-2.6.32 pve-kernel-3.10.0 pve-kernel-3.19.0 We use 'find-firmware.pl' to extract lists of required firmeware files. The script 'assemble-firmware.pl' is used to read those lists and copy the files from various source directory into a target directory. We do not include firmeware for some wireless HW when there is a separate debian package for that, for example: zd1211-firmware atmel-firmware bluez-firmware PATCHES: -------- bridge-patch.diff: Avoid bridge problems with changing MAC see also: http://forum.openvz.org/index.php?t=msg&th=5291 Behaviour after 2.6.27 has changed slighly - after setting mac address of bridge device, then address won't change. So we could omit that patch, requiring to set hwaddress in /etc/network/interfaces. Watchdog blacklist ------------------ By default, all watchdog modules are black-listed because it is totally undefined which device is actually used for /dev/watchdog. We ship this list in /lib/modprobe.d/blacklist_pve-kernel-<VERSION>.conf The user typically edit /etc/modules to enable a specific watchdog device. Additional information ---------------------- We use the default configuration provided by Ubuntu, and apply the following modification: see Makefile (PVE_CONFIG_OPTS) - enable CONFIG_CEPH_FS=m (request from user) - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection problems (udev, undate-initramfs have serious problems without that) CONFIG_BLK_DEV_SD=y CONFIG_BLK_DEV_SR=y CONFIG_BLK_DEV_DM=y - add workaround for Debian bug #807000 (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807000) CONFIG_BLK_DEV_NVME=y - compile NBD and RBD modules CONFIG_BLK_DEV_NBD=m CONFIG_BLK_DEV_RBD=m - set LOOP_MIN_COUNT to 8 (debian defaults) CONFIG_BLK_DEV_LOOP_MIN_COUNT=8 - disable module signatures (CONFIG_MODULE_SIG) - enable IBM JFS file system This is disabled in RHEL kernel for no real reason, so we enable it as requested by users (bug #64) - enable apple HFS and HFSPLUS This is disabled in RHEL kernel for no real reason, so we enable it as requested by users - enable CONFIG_BCACHE=m (requested by user) - enable CONFIG_BRIDGE=y Else we get warnings on boot, that net.bridge.bridge-nf-call-iptables is an unknown key - enable CONFIG_DEFAULT_SECURITY_APPARMOR We need this for lxc - set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y because if not set, it can give some dynamic memory or cpu frequencies change, and vms can crash (mainly windows guest). see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273 - use 'deadline' as default scheduler This is the suggested setting for KVM. We also measure bad fsync performance with ext4 and cfq. - disable CONFIG_INPUT_EVBUG Module evbug is not blacklisted on debian, so we simply disable it to avoid key-event logs (which is a big security problem) Testing final kernel with kvm ----------------------------- kvm -kernel data/boot/vmlinuz-3.19.8-1-pve -initrd initrd.img-3.19.8-1-pve -append "vga=791 video=vesafb:ywrap,mtrr" /dev/zero
