  46 FIRMWARE:
  47 =========
  48
  49 We create our own firmware package, which includes the firmware for
  50 all proxmox-ve kernels. So far this include
  51
  52 pve-kernel-2.6.18
  53 pve-kernel-2.6.24
  54 pve-kernel-2.6.32
  55 pve-kernel-2.6.35
  56 pve-kernel-3.10.0
  57
  58 We use 'find-firmware.pl' to extract lists of required firmeware
  59 files.  The script 'assemble-firmware.pl' is used to read those lists
  60 and copy the files from various source directory into a target
  61 directory.
  62
  63 We do not include firmeware for some wireless HW when there is a
  64 separate debian package for that, for example:
  65
  66 zd1211-firmware
  67 atmel-firmware
  68 bluez-firmware

  71 PATCHES:
  72 --------
  73
  74  bridge-patch.diff: Avoid bridge problems with changing MAC
  75   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  76
  77   Behaviour after 2.6.27 has changed slighly - after setting mac address
  78   of bridge device, then address won't change. So we could omit
  79   that patch, requiring to set hwaddress in /etc/network/interfaces.

  81
  82 Additional information
  83 ----------------------
  84
  85 We use the default configuration provided by RHEL, and apply
  86 the following modification:
  87
  88 see config-3.10.0.diff
  89
  90 - enable CONFIG_CEPH_FS=m (request from user)
  91
  92 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  93   problems (udev, undate-initramfs hav serious problems without that)
  94
  95          CONFIG_BLK_DEV_SD=y
  96          CONFIG_BLK_DEV_SR=y
  97          CONFIG_BLK_DEV_DM=y
  98
  99 - compile NBD and RBD modules
 100          CONFIG_BLK_DEV_NBD=m
 101          CONFIG_BLK_DEV_RBD=m
 102
 103 - set LOOP_MIN_COUNT to 8 (debian defaults)
 104          CONFIG_BLK_DEV_LOOP_MIN_COUNT=8
 105
 106 - disable module signatures (CONFIG_MODULE_SIG)
 107
 108 - enable IBM JFS file system
 109
 110   This is disabled in RHEL kernel for no real reason, so we enable
 111   it as requested by users (bug #64)
 112
 113 - enable apple HFS and HFSPLUS
 114
 115   This is disabled in RHEL kernel for no real reason, so we enable
 116   it as requested by users
 117
 118 - enable CONFIG_BCACHE=m (requested by user)
 119
 120 - enable CONFIG_BRIDGE=y
 121
 122   Else we get warnings on boot, that
 123   net.bridge.bridge-nf-call-iptables is an unknown key
 124
 125 - disable CONFIG_DEFAULT_SECURITY_SELINUX
 126
 127   Use same SELINUX config as debian kernels (CONFIG_DEFAULT_SECURITY_DAC=y)
 128
 129 - set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
 130
 131   because if not set, it can give some dynamic memory or cpu frequencies
 132   change, and vms can crash (mainly windows guest).
 133
 134   see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273
 135
 136 - set CONFIG_CC_STACKPROTECTOR_REGULAR=y
 137
 138   gcc on debian wheezy does not supportCONFIG_CC_STACKPROTECTOR_STRONG
 139
 140 # Note: enable now for testing
 141 #- disable CONFIG_BRIDGE_IGMP_SNOOPING
 142 #
 143 # To avoid problems with multicasting. Various users reported
 144 #  multipath problems, which can be avoided by turning off IGMP
 145 # snooping.
 146
 147 # deadline is default anyways now
 148 #- use 'deadline' as default scheduler
 149 #
 150 #  This is the suggested setting for KVM. We also measure bad fsync
 151 #  performance with ext4 and cfq.
 152
 153 Testing final kernel with kvm
 154 -----------------------------
 155
 156 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
