2021-03-08hw/dma: Implement a Xilinx CSU DMA modelXuzhou Cheng
ZynqMP QSPI supports SPI transfer using DMA mode, but currently this is unimplemented. When QSPI is programmed to use DMA mode, QEMU will crash. This is observed when testing VxWorks 7. This adds a Xilinx CSU DMA model and the implementation is based on https://github.com/Xilinx/qemu/blob/master/hw/dma/csu_stream_dma.c. The DST part of the model is verified along with ZynqMP GQSPI model. Signed-off-by: Xuzhou Cheng <xuzhou.cheng@windriver.com> Signed-off-by: Bin Meng <bin.meng@windriver.com> Tested-by: Edgar E.

2021-02-03hw/arm/xlnx-versal: Versal SoC requires ZDMAPhilippe Mathieu-Daudé
The Versal SoC instantiates the TYPE_XLNX_ZDMA object in versal_create_admas(). Introduce the XLNX_ZDMA configuration and select it to fix: $ qemu-system-aarch64 -M xlnx-versal-virt ... qemu-system-aarch64: missing object type 'xlnx.zdma' Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-id: 20210131184449.382425-4-f4bug@amsat.org Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2020-09-09hw/dma: Add SiFive platform DMA controller emulationBin Meng
Microchip PolarFire SoC integrates a DMA engine that supports: * Independent concurrent DMA transfers using 4 DMA channels * Generation of interrupts on various conditions during execution which is actually an IP reused from the SiFive FU540 chip. This creates a model to support both polling and interrupt modes.

2019-08-20hw/core: Add a config switch for the "register" deviceThomas Huth
The "register" device is only used by certain machines. Let's add a proper config switch for it so that it only gets compiled when we really need it.

2019-03-07kconfig: introduce kconfig filesPaolo Bonzini
The Kconfig files were generated mostly with this script: for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' ` shift if test $# = 1; then cat >> $(dirname $1)/Kconfig << EOF config ${i#CONFIG_} bool EOF git add $(dirname $1)/Kconfig else echo $i $* fi done sed -i '$d' hw/*/Kconfig for i in hw/*; do if test -d $i && ! test -f $i/Kconfig; then touch $i/Kconfig git add $i/Kconfig fi done Whenever a symbol is referenced from multiple subdirectories, the script prints the list of directories that reference the symbol. These symbols have to be added manually to the Kconfig files. Kconfig.host and hw/Kconfig were created manually.
