Welcome to the qemu wiki!

TODO

• NCSI support

  • currently only a fake user mode network stack (slirp) backend.

• OCC model

• LPC controller

• GPIO Controller

  • should be useful for debug.
  • RX8900 INT line should be connected to GPIOJ0 for Witherspoon (This is needed if RTC alarms are used)

• Clock infrastructure

  • Derive clock rates from strapping and SCU clock registers
  • review proposal from Frederic KONRAD

• MBOX

Development in progress

Controllers

• I2C

  • DMA support (used by Aspeed SDK 4)

• BT device (part of the LPC Controller)

  • initial implementation done
  • provide a backend for an external connection with the pnv machine.

• VUART Controller

  • dummy implementation done (no shared registers with the host)
  • over LPC
  • use -chardev for external connection

• Network FTGMAC100

  • linux basic support for kernel 4.7, 4.10, and new driver from benh
  • u-boot support ok. can tftp an image to boot.
  • missing features :
    • NCSI (only on user mode network stack)
    • IEEE 802.1Q VLAN
    • High Priority Transmit Queue
    • Wake-On-LAN functions

• SMC:

  • dummy bytes for fast read in user mode
  • DMA (rework current implementation with a private address space)

• SuperIO

  • required For OpenPOWER systems to access the flash. Will change in P9.

• rx8900 RTC (Romulus machine)
