  45 FIRMWARE:
  46 =========
  47
  48 We create our own firmware package, which includes the firmware for
  49 all proxmox-ve kernels. So far this include
  50
  51 pve-kernel-2.6.18
  52 pve-kernel-2.6.24
  53 pve-kernel-2.6.32
  54 pve-kernel-2.6.35
  55
  56 We use 'find-firmware.pl' to extract lists of required firmeware
  57 files.  The script 'assemble-firmware.pl' is used to read those lists
  58 and copy the files from various source directory into a target
  59 directory.
  60
  61 We do not include firmeware for some wireless HW when there is a
  62 separate debian package for that, for example:
  63
  64 zd1211-firmware
  65 atmel-firmware
  66 bluez-firmware
  67
  68
  69 PATCHES:
  70 --------
  71
  72  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  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.
  80
  81
  82 Additional information
  83 ----------------------
  84
  85 We use the default configuration provided by openvz, and apply
  86 the following modification:
  87
  88 see config-2.6.32.diff
  89
  90 - enable bootsplash
  91         CONFIG_FB_VESA=y
  92         CONFIG_FRAMEBUFFER_CONSOLE=Y
  93         CONFIG_BOOTSPLASH=y
  94
  95 - disable CONFIG_DEBUG_INFO
  96
  97 - disable CONFIG_PRINTK_TIME
  98
  99 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
 100   problems (udev, undate-initramfs hav serious problems without that)
 101
 102          CONFIG_BLK_DEV_SD=y
 103          CONFIG_BLK_DEV_SR=y
 104          CONFIG_BLK_DEV_DM=y
 105
 106 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
 107
 108 - enable usbip (this is also enable on debian kernels)
 109
 110          CONFIG_USB_IP_COMMON=m
 111          CONFIG_USB_IP_VHCI_HCD=m
 112          CONFIG_USB_IP_HOST=m
 113
 114 - enable IBM JFS file system
 115
 116   This is disabled in RHEL kernel for no real reason, so we enable
 117   it as requested by users (bug #64)
 118
 119 - enable apple HFS and HFSPLUS
 120
 121   This is disabled in RHEL kernel for no real reason, so we enable
 122   it as requested by users
 123
 124 - enable CONFIG_BRIDGE=y
 125
 126   Else we get warnings on boot, that
 127   net.bridge.bridge-nf-call-iptables is an unknown key
 128
 129 - disable CONFIG_BRIDGE_IGMP_SNOOPING
 130
 131   To avoid problems with multicasting. Various users reported
 132   multipath problems, which can be avoided by turning off IGMP
 133   snooping.
 134
 135 - use 'deadline' as default scheduler
 136
 137   This is the suggested setting for KVM. We also measure bad fsync
 138   performance with ext4 and cfq.
 139
 140 Testing final kernel with kvm
 141 -----------------------------
 142
 143 kvm -kernel data/boot/vmlinuz-2.6.32-6-pve -initrd initrd.img-2.6.32-6-pve -append "vga=791 video=vesafb:ywrap,mtrr splash=silent" /dev/zero
