x86 does not use CONFIG_GENERIC_MSI_IRQ, and trying to enable it anyway
results in a build failure:
In file included from include/linux/ssb/ssb.h:10,
from drivers/ssb/pcihost_wrapper.c:18:
include/linux/gpio/driver.h:41:33: error: field 'msiinfo' has incomplete type
41 | msi_alloc_info_t msiinfo;
| ^~~~~~~
In file included from include/linux/kvm_host.h:19,
from arch/x86/events/intel/core.c:17:
include/linux/msi.h:528:33: error: field 'alloc_info' has incomplete type
528 | msi_alloc_info_t alloc_info;
Change the driver to actually build without this symbol and remove the
incorrect 'select' statements.

Driver to enable Composable DMA Transfer(CDX) Bus. CDX bus
|
|
exposes Fabric devices which uses composable DMA IP to the
|
|
APU. CDX bus provides a mechanism for scanning and probing
|
|
of CDX devices. CDX devices are memory mapped on system bus
|
|
for embedded CPUs. CDX bus uses CDX controller and firmware
|
|
to scan these CDX devices.
