List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: edgar.iglesias@xilinx.com, peter.maydell@linaro.org, hyunk@xilinx.com, mark.burton@greensocs.com, alistair.francis@xilinx.com, crosthwaitepeter@gmail.com, guillaume.delbergue@greensocs.com, fred.konrad@greensocs.com From: KONRAD Frederic This is the 7th version of this patch-set of the implementation of the Xilinx DisplayPort and DPDMA. This 7th version fixes some minors issues. 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: git@git.greensocs.com:fkonrad/xilinx_dp.git branch xilinx_dp_v7_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 V6 -> V7 changes: * globally: * Rebased on current master (0430891ce162b986c6e02a7729a942ecd2a32ca4). * Pick Peter's patch-set and rebase it on broadcast patch. * xlnx-dp: * Print some unimplemented debug trace instead of aborting. * zynq-mp: * Set realized before map the device. * Conding style fix. * aux: * Factorize i2c access with i2c_send_recv. V5 -> V6 changes: * globally: * Rebased on current master (38a762fec63fd5c035aae29ba9a77d357e21e4a7). * Fix some coding style issues. V4 -> V5 changes: * aux: * Move the header include/hw => include/hw/misc * dpcd: * Move the header hw/display => include/hw/display * i2c-ddc: * Move the header hw/i2c => include/hw/i2c * xlnx-dpdma: * Move the header hw/dma => include/hw/dma * Fix some styles issues. * xlnx-dp: * Move the header hw/display => include/hw/display * globally: * Rebased on current master (c49d3411faae8ffaab8f7e5db47405a008411c10).
