This will likely break many of the Xilinx flows with automatic dts to qemu property conversions so I don't think it's a good idea to rename it. If you like to clarify things perhaps we could keep an alias for the old one? For example: https://github.com/torvalds/linux/blob/master/arch/microblaze/boot/dts/sy...

The petalogix-ml605 machine was explicitly added as little-endian only machine in commit 00914b7d970 ("microblaze: Add PetaLogix ml605 MMU little-endian ref design"). Mark the big-endian version as deprecated. When the xlnx-zynqmp-pmu machine's CPU was added in commit 133d23b3ad1 ("xlnx-zynqmp-pmu: Add the CPU and memory"), its 'endianness' property was set to %true, thus wired in little endianness. Both machine are included in the big-endian system binary, while their CPU is working in little-endian. Unlikely to work as it. Deprecate now as broken config so we can remove soon.

By default the machine's CPU endianness is 'big' order ('little-endian' property set to %false). This corresponds to the default when this machine was added; see commits 6a8b1ae2020 "microblaze: Add petalogix s3a1800dsp MMU linux ref-design." and 72b675caacf "microblaze: Hook into the build-system." which added: [ "$target_cpu" = "microblaze" ] && target_bigendian=yes Later commit 877fdc12b1a ("microblaze: Allow targeting little-endian mb") added little-endian support, forgetting to set the CPU endianness to little-endian. Not an issue since this property was never used, but we will use it soon, so explicit the endianness to get the expected behavior.

Indeed the latter seems to extend the former, but they are not the same and we need some work to model the latter. The endianness explicit for each model (and is not listed in the "IP Configurable Design Parameters" tables). That said, let's look at Linux use.

This is from 2014, maybe to work with the "LogiCORE IP AXI INTC" you mentioned, which spec date is 2013. Indeed when forcing different endianness [*], the Linux kernel used in our tests (tests/functional/test_microblaze*) does the check and ends up using the correct INTC endianness: LE CPU, LE INTC model pic_write addr=8 val=0 pic_write addr=c val=ffffffff pic_write addr=1c val=3 <- LE pic_read 1c=3 pic_write addr=c val=1 pic_write addr=10 val=1 pic_read 18=0 LE CPU, BE INTC model pic_write addr=8 val=0 pic_write addr=c val=ffffffff pic_write addr=1c val=3000000 <- LE test pic_read 1c=0 pic_write addr=1c val=3 <- BE pic_write addr=c val=1 pic_write addr=10 val=1 pic_read 18=0 BE CPU, BE INTC model pic_write addr=8 val=0 pic_write addr=c val=ffffffff pic_write addr=1c val=3000000 <- LE test pic_read 1c=0 pic_write addr=1c val=3 <- BE pic_write addr=c val=1 pic_write addr=10 val=1 pic_read 18=0 BE CPU, LE INTC model pic_write addr=8 val=0 pic_write addr=c val=ffffffff pic_write addr=1c val=3 <- LE pic_read 1c=3 pic_write addr=c val=1 pic_write addr=10 val=1 pic_read 18=0 IMHO this patch behavior is correct. Besides, I don't expect firmwares to be as clever as Linux. What you suggested is implemented in v3: https://lore.kernel.org/qemu-devel/20241108154317.12129-4-philmd@linaro.org/ but after the analysis, I wonder if it isn't safer to not make the endianness configurable, but expose as 2 models: - xlnx,xps_intc (2010) in BE - xlnx,axi_intc (2013) in LE [*] diff used: -- >8 -- @@ -32,7 +45,7 @@ diff --git a/hw/intc/xilinx_intc.c b/hw/intc/xilinx_intc.c index fc55c8afca..883ec685f4 100644 --- a/hw/intc/xilinx_intc.c +++ b/hw/intc/xilinx_intc.c #include "hw/qdev-properties.h" #include "qom/object.h" -#define D(x) +#define D(x) x #define R_ISR 0 #define R_IPR 1 @@ -105,7 +122,7 @@ static uint64_t pic_read(void *opaque, hwaddr addr, unsigned int size) break; } - D(printf("%s %x=%x\n", __func__, addr * 4, r)); + D(printf("%s %llx=%x\n", __func__, addr * 4, r)); return r; } @@ -116,7 +133,7 @@ static void pic_write(void *opaque, hwaddr addr, uint32_t value = val64; addr >>= 2; - D(qemu_log("%s addr=%x val=%x\n", __func__, addr * 4, value)); + D(printf("%s addr=%llx val=%x\n", __func__, addr * 4, value)); switch (addr) { case R_IAR: ---
