  42 FIRMWARE:
  43 =========
  44
  45 We create our own firmware package, which includes the firmware for
  46 all proxmox-ve kernels. So far this include
  47
  48 pve-kernel-2.6.18
  49 pve-kernel-2.6.24
  50 pve-kernel-2.6.32
  51 pve-kernel-2.6.35
  52 pve-kernel-3.10.0
  53
  54 We use 'find-firmware.pl' to extract lists of required firmeware
  55 files.  The script 'assemble-firmware.pl' is used to read those lists
  56 and copy the files from various source directory into a target
  57 directory.
  58
  59 We do not include firmeware for some wireless HW when there is a
  60 separate debian package for that, for example:
  61
  62 zd1211-firmware
  63 atmel-firmware
  64 bluez-firmware
  65
  66
  67 PATCHES:
  68 --------
  69
  70  bridge-patch.diff: Avoid bridge problems with changing MAC
  71   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  72
  73   Behaviour after 2.6.27 has changed slighly - after setting mac address
  74   of bridge device, then address won't change. So we could omit
  75   that patch, requiring to set hwaddress in /etc/network/interfaces.
  76
  77
  78 Additional information
  79 ----------------------
  80
  81 We use the default configuration provided by RHEL, and apply
  82 the following modification:
  83
  84 see config-3.10.0.diff
  85
  86 - enable CONFIG_CEPH_FS=m (request from user)
  87
  88 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  89   problems (udev, undate-initramfs hav serious problems without that)
  90
  91          CONFIG_BLK_DEV_SD=y
  92          CONFIG_BLK_DEV_SR=y
  93          CONFIG_BLK_DEV_DM=y
  94
  95 - compile NBD and RBD modules
  96          CONFIG_BLK_DEV_NBD=m
  97          CONFIG_BLK_DEV_RBD=m
  98
  99 - set LOOP_MIN_COUNT to 8 (debian defaults)
 100          CONFIG_BLK_DEV_LOOP_MIN_COUNT=8
 101
 102 - disable module signatures (CONFIG_MODULE_SIG)
 103
 104 - enable IBM JFS file system
 105
 106   This is disabled in RHEL kernel for no real reason, so we enable
 107   it as requested by users (bug #64)
 108
 109 - enable apple HFS and HFSPLUS
 110
 111   This is disabled in RHEL kernel for no real reason, so we enable
 112   it as requested by users
 113
 114 - enable CONFIG_BCACHE=m (requested by user)
 115
 116 - enable CONFIG_BRIDGE=y
 117
 118   Else we get warnings on boot, that
 119   net.bridge.bridge-nf-call-iptables is an unknown key
 120
 121 - disable CONFIG_DEFAULT_SECURITY_SELINUX
 122
 123   Use same SELINUX config as debian kernels (CONFIG_DEFAULT_SECURITY_DAC=y)
 124
 125 - set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
 126
 127   because if not set, it can give some dynamic memory or cpu frequencies
 128   change, and vms can crash (mainly windows guest).
 129
 130   see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273
 131
 132 - set CONFIG_CC_STACKPROTECTOR_REGULAR=y
 133
 134   gcc on debian wheezy does not supportCONFIG_CC_STACKPROTECTOR_STRONG
 135
 136 # Note: enable now for testing
 137 #- disable CONFIG_BRIDGE_IGMP_SNOOPING
 138 #
 139 # To avoid problems with multicasting. Various users reported
 140 #  multipath problems, which can be avoided by turning off IGMP
 141 # snooping.
 142
 143 # deadline is default anyways now
 144 #- use 'deadline' as default scheduler
 145 #
 146 #  This is the suggested setting for KVM. We also measure bad fsync
 147 #  performance with ext4 and cfq.
 148
 149 Testing final kernel with kvm
 150 -----------------------------
 151
 152 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
