Hello,
the BSPs for the Xilinx Zynq/ZynqMP/Versal platforms use code from
Xilinx. They also install some header files from Xilinx in the
top-level include directory of the BSP, for example:
sleep.h xbasic_types.h xil_assert.h xil_cache.h xil_exception.h
xil_io.h xil_mem.h xil_printf.h xil_smc.h xil_types.h xparameters.h
xpseudo_asm_gcc.h xpseudo_asm.h xreg_cortexa53.h xstatus.h
This can lead to conflicts if I would like to build software from
https://github.com/Xilinx/embeddedsw
because now some header files are duplicated and available through
different include paths. Why do we install these header files? I think
they should be only used internally to build the BSP provided drivers.
The RTEMS drivers should expose their interfaces not through the
Xilinx header files.
Any objections to remove the installation of the Xilinx header files?
Dear Sebastian,
Zynq 7000 is not using them. Rtems-lwip requires some of the headers. I
provided a patch which added "objxilinxsupport.yml" to the Zynq 7000
configurations. After a discussion on Discord my patch was rolled back
(which I think was a good decision).
Chris and Kinsey, please correct me if I misunderstood something, but as
far as I understood it the headers will be removed from the kernel.
Afaik, there are some drivers for the ZU require them. Thus, it will
require some time / planning to overwork the drivers and move the
required headers to rtems-lwip.
Long story short, Chris and Kinsey should be able to give some more
detailed information on the strategy and timeline.
Maybe one option is to install the BSP-provided Xilinx headers in bsp/,
for example:
#include <bsp/xparameters.h>
