If we add an intermediate level of "CPU IO address space", it makes things a little more complicated but I don't see any real benefit. If we just make a simple policy that on ARM/AARCH64 CPU IO address is equal to CPU memory address, we can even use a unified CPU IO driver for all ARM/AARCH64 platforms, while the translation is covered by PCI host bridge driver. 2. From hardware perspective, the translation is done by PCIe ATU; for IO bar access, the address from CPU to ATU is a CPU memory address, not an intermediate CPU IO address; the intermediate CPU IO address is a totally logical concept, and it also splits ATU function into separate drivers (CPU IO protocol driver also sees part of ATU function). Please let me know if my understanding is not right. > - please fix the APPETURE spelling (in whichever way is most > convenient for you: separate patch at the beginning, at the end, etc > etc) Nice catch :) will fix that.

Hi Ard, Any comments? Anyway we can modify the code if you insist on using an intermediate CPU IO address space.

I agree there is a certain elegance to merging both translations, but I am concerned that existing EDK2 code may deal poorly with I/O addresses that require more than 32 bits to express. Did you try the mm command in the shell for instance? As you know, I recently removed an artificial address range limit there, but I wonder if it uses 64-bit variables for I/O ports. _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
Thanks, I will test mm command and let you know the result.

Hi Ard, I tested mm -io on D05, for root bridge 4 with CPU IO address starting from 0x8_abff0000, and it worked; both mm -io 0x8abff0000 and mm 0x8abff0000 provided the same output. It seems there is no other limit for 64bit IO address after you fixed the issue in EFI shell mm command.

BTW, there is actually a bug with ATU configuration which will cause IO access failure, and we need to apply an additional patch (this patch is generated after PCI host bridge patch series) as attached to fix this.
