[Qemu-devel] [PATCH V10 0/9] Xilinx DisplayPort. |

From: KONRAD Frederic <address@hidden>
This is the 10th version of this patch-set of the implementation of the Xilinx
DisplayPort and DPDMA.
This 10th version fixes one bug with the I2C broadcast patch.
The fourth patch introduces an AUX bus needed by the DP to read the DPCD.
It's also possible to connect an I2C device on it to do I2C through AUX
commands. The drivers requires I2C broadcast write to be modeled as well which
seemed to be missing currently upstream.
The tree can be cloned at:
address@hidden:fkonrad/xilinx_dp.git branch xilinx_dp_v10_release
Details of the DPDMA part:
* DPDMA is implemented as a QEMU SYSBUS device.
* Interrupts are implemented except the axi error and fifo.
Details of the XILINX-DP:
* DP is also implemented as a QEMU SYSBUS. Multiple memory regions are used to
avoid having a single big region as there are holes in the DP memory map.
* An aux-bus has been implemented, it creates a memory map for aux slaves and
has an i2c bus (which is already implemented in QEMU).
* The normal programmable i2c clock and controller implementation is missing
from the QEMU tree so the easiest way for us was to implement a dummy-clk
driver in the kernel. It's a clock which does nothing but fakes a clock such
that the DPDMA driver works. The patch will be send separately.
* The graphic plane works on channel 3, video on channel 0 and audios on
channel 4 and 5.
Thanks,
Fred

* other:
* Drop the useless "console: add qemu_alloc_display_format." patch as
suggested by Gerd.
* Rebase on current master (f3e3b083d4c266ea864ae3c83da49d4086857679).
