build error on x86, file dmaSendFd.h, line 85 about connectal HOT 8 OPEN

can you post the error message?

from connectal.

Are you sure that addr is 32 bits on x86? we always run 64-bit versions,
so seems peculiar.

In addition, I am accustomed to sizeof(long) == sizeof(void *), for
example, see the last line of the next-to-last paragraph of:
http://www.makelinux.net/ldd3/chp-11-sect-1
( was looking for this in the c std, but can't find similar text... :-( )

Thanks

Below is error message, the problem is Shift 32 bits and OR with addr
btw: the dma_addr_t defined in Linux header, so it maybe 32 or 64bits depends OS configure.

I see. This is code only for simulations.
It appears that simulation builds (xsim, bluesim, modelsim, verilator) have
to be run on 64-bit architectures (which, in practice, are always x86).

I would highly recommend switching to a machine with a 64-bit OS. (since
the 32 bit os can't address much memory anyway for simulation...)

Is that possible?

I feel like I'm hearing half of a phone conversation.

@chenm001, it would be possible to put together a simulation configuration that supports 32-bit x86, but I agree with @jankcorn that it would be better to switch to 64-bit x86. Because who knows how many other places we assumed x86 was 64bit.

from connectal.

Agree, for really world, we may use x64 OS.
In simluate enviorment, I simple workaround by modify local to 'uint64_t addr;'

from connectal.

If that change works, I think we could update dmaSendFd.h accordingly.

We do not have any 32-bit x86 systems to test with, so please let us know
if any other changes are required.

I will do more test and let you know later
