[Qemu-devel] [PATCH v3 0/5] Raspberry Pi framebuffer, DMA and Windows su

From: Andrew Baumann
Subject: [Qemu-devel] [PATCH v3 0/5] Raspberry Pi framebuffer, DMA and Windows support
Date: Tue, 8 Mar 2016 12:05:21 -0800

This patch series adds support for the AUX (second UART), framebuffer
and DMA controller on Raspberry Pi 2, and enables booting Windows on
this device. As with the previous series, it is heavily based on the
original (out of tree) work of Gregory Estrade, Stefan Weil and others
to support Raspberry Pi 1.

After this series, it is possible to boot Windows by following the
instructions at https://github.com/0xabu/qemu/wiki. You also boot
Raspbian to the GUI using a command such as:

  qemu-system-arm -M raspi2 -kernel raspbian-boot/kernel7.img -sd
  2015-09-24-raspbian-jessie.img -append "rw earlyprintk loglevel=8
  console=ttyAMA0 dwc_otg.lpm_enable=0 root=/dev/mmcblk0p2 rootwait"
  -dtb raspbian-boot/bcm2709-rpi-2-b.dtb -serial stdio

I plan to add USB, and remaining timers / system devices in
future patch series, along with support for pi1 (bcm2835). In the
meantime, the complete code is available at https://github.com/0xabu/qemu

 * added DMA controller
 * revised per PMM's review feedback
 * rebased on top of the patch for fixing ldl_phys/stl_phys in raspi
   devices, presently in target-arm.next

 * tweaked instantiation of uart1 char device
 * identified Gregory as primary author of framebuffer and DMA emulation


Andrew Baumann (2):
  bcm2835_peripherals: enable sdhci pending-insert quirk for raspberry
  bcm2835_aux: add emulation of BCM2835 AUX (aka UART1) block

Grégory ESTRADE (3):
  bcm2835_fb: add framebuffer device for Raspberry Pi
  bcm2835_property: implement framebuffer control/configuration
  bcm2835_dma: add emulation of Raspberry Pi DMA controller
