  48 FIRMWARE:
  49 =========
  50
  51 We create our own firmware package, which includes the firmware for
  52 all proxmox-ve kernels. So far this include
  53
  54 pve-kernel-2.6.18
  55 pve-kernel-2.6.24
  56 pve-kernel-2.6.32
  57 pve-kernel-2.6.35
  58 pve-kernel-3.10.0
  59
  60 We use 'find-firmware.pl' to extract lists of required firmeware
  61 files.  The script 'assemble-firmware.pl' is used to read those lists
  62 and copy the files from various source directory into a target
  63 directory.
  64
  65 We do not include firmeware for some wireless HW when there is a
  66 separate debian package for that, for example:
  67
  68 zd1211-firmware
  69 atmel-firmware
  70 bluez-firmware
  71
  72
  73 PATCHES:
  74 --------
  75
  76  bridge-patch.diff: Avoid bridge problems with changing MAC
  77   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  78
  79   Behaviour after 2.6.27 has changed slighly - after setting mac address
  80   of bridge device, then address won't change. So we could omit
  81   that patch, requiring to set hwaddress in /etc/network/interfaces.
  82
  83
  84 Additional information
  85 ----------------------
  86
  87 We use the default configuration provided by RHEL, and apply
  88 the following modification:
  89
  90 see config-3.10.0.diff
  91
  92 - enable CONFIG_CEPH_FS=m (request from user)
  93
  94 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  95   problems (udev, undate-initramfs hav serious problems without that)
  96
  97          CONFIG_BLK_DEV_SD=y
  98          CONFIG_BLK_DEV_SR=y
  99          CONFIG_BLK_DEV_DM=y
 100
 101 - compile NBD and RBD modules
 102          CONFIG_BLK_DEV_NBD=m
 103          CONFIG_BLK_DEV_RBD=m
 104
 105 - set LOOP_MIN_COUNT to 8 (debian defaults)
 106          CONFIG_BLK_DEV_LOOP_MIN_COUNT=8
 107
 108 - disable module signatures (CONFIG_MODULE_SIG)
 109
 110 - enable IBM JFS file system
 111
 112   This is disabled in RHEL kernel for no real reason, so we enable
 113   it as requested by users (bug #64)
 114
 115 - enable apple HFS and HFSPLUS
 116
 117   This is disabled in RHEL kernel for no real reason, so we enable
 118   it as requested by users
 119
 120 - enable CONFIG_BCACHE=m (requested by user)
 121
 122 - enable CONFIG_BRIDGE=y
 123
 124   Else we get warnings on boot, that
 125   net.bridge.bridge-nf-call-iptables is an unknown key
 126
 127 - disable CONFIG_DEFAULT_SECURITY_SELINUX
 128
 129   Use same SELINUX config as debian kernels (CONFIG_DEFAULT_SECURITY_DAC=y)
 130
 131 - set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
 132
 133   because if not set, it can give some dynamic memory or cpu frequencies
 134   change, and vms can crash (mainly windows guest).
 135
 136   see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273
 137
 138 - set CONFIG_CC_STACKPROTECTOR_REGULAR=y
 139
 140   gcc on debian wheezy does not supportCONFIG_CC_STACKPROTECTOR_STRONG
 141
 142 # Note: enable now for testing
 143 #- disable CONFIG_BRIDGE_IGMP_SNOOPING
 144 #
 145 # To avoid problems with multicasting. Various users reported
 146 #  multipath problems, which can be avoided by turning off IGMP
 147 # snooping.
 148
 149 # deadline is default anyways now
 150 #- use 'deadline' as default scheduler
 151 #
 152 #  This is the suggested setting for KVM. We also measure bad fsync
 153 #  performance with ext4 and cfq.
 154
 155 Testing final kernel with kvm
 156 -----------------------------
 157
 158 kvm -kernel data/boot/vmlinuz-3.10.0-2-pve -initrd initrd.img-3.10.0-2-pve -append "vga=791 video=vesafb:ywrap,mtrr" /dev/zero
