When compiling the x86 kernel, if X86_64 || SMP || X86_32_NON_STANDARD ||
X86_UP_APIC || PCI_MSI is not enabled in '.config' and GENERIC_MSI_IRQ is
selected, the following compilation error will occur:
> include/linux/gpio/driver.h:38:19: error:

This is because 'X86_LOCAL_APIC' is not defined, but file such as
'kernel/irq/msi.c' only depends on 'GENERIC_MSI_IRQ', and uses
'struct msi_alloc_info_t'. When enable 'GENERIC_MSI_IRQ' will select
'IRQ_DOMAIN_HIERARCHY', so exposing this struct using
'IRQ_DOMAIN_HIERARCHY' rather than 'X86_LOCAL_APIC'.

Thank for the patch. This reduces the build error count from around 190 down to
two remaining problems for me:
../arch/x86/kernel/hpet.c: In function ‘hpet_create_irq_domain’:
../arch/x86/kernel/hpet.c:550:13: error: ‘x86_vector_domain’ undeclared (first use in this function)
550 | if (x86_vector_domain == NULL)
| ^~~~~~~~~~~~~~~~~
../arch/x86/kernel/hpet.c:550:13: note: each undeclared identifier is reported only once for each function it appears in
../arch/x86/kernel/hpet.c: In function ‘hpet_assign_irq’:
../arch/x86/kernel/hpet.c:600:9: error: implicit declaration of function ‘init_irq_alloc_info’ [-Werror=implicit-function-declaration]
600 | init_irq_alloc_info(&info, NULL);
| ^~~~~~~~~~~~~~~~~~~
I haven't looked into how to fix this yet...

When compiling the x86 kernel, if X86_LOCAL_APIC is not enabled but
GENERIC_MSI_IRQ is selected in '.config', the following compilation
error will occur:
include/linux/gpio/driver.h:38:19: error:
field 'msiinfo' has incomplete type
kernel/irq/msi.c:752:5: error: invalid use of incomplete typedef
'msi_alloc_info_t' {aka 'struct irq_alloc_info'}
kernel/irq/msi.c:740:1: error: control reaches end of non-void function
This is because file such as 'kernel/irq/msi.c' only depends on
'GENERIC_MSI_IRQ', and uses 'struct msi_alloc_info_t'. However,
this struct depends on 'X86_LOCAL_APIC'.
When enable 'GENERIC_MSI_IRQ' or 'X86_LOCAL_APIC' will select
'IRQ_DOMAIN_HIERARCHY', so exposing this struct using
'IRQ_DOMAIN_HIERARCHY' rather than 'X86_LOCAL_APIC'.
Under the above conditions, if 'HPET_TIMER' is selected, the following
compilation error will occur:
arch/x86/kernel/hpet.c:550:13: error: ‘x86_vector_domain’ undeclared
arch/x86/kernel/hpet.c:600:9: error: implicit declaration of
function ‘init_irq_alloc_info’
This is because 'x86_vector_domain' is defined in 'kernel/apic/vector.c'
which is compiled only when 'X86_LOCAL_APIC' is enabled. So use
'X86_LOCAL_APIC' to expose these code rather than 'GENERIC_MSI_IRQ'.

When compiling the x86 kernel, if X86_LOCAL_APIC is not enabled but
GENERIC_MSI_IRQ is selected in '.config', the following compilation
error will occur:
include/linux/gpio/driver.h:38:19: error:
field 'msiinfo' has incomplete type
kernel/irq/msi.c:752:5: error: invalid use of incomplete typedef
'msi_alloc_info_t' {aka 'struct irq_alloc_info'}
kernel/irq/msi.c:740:1: error: control reaches end of non-void function
This is because file such as 'kernel/irq/msi.c' only depends on
'GENERIC_MSI_IRQ', and uses 'struct msi_alloc_info_t'. However,
this struct depends on 'X86_LOCAL_APIC'.
When enable 'GENERIC_MSI_IRQ' or 'X86_LOCAL_APIC' will select
'IRQ_DOMAIN_HIERARCHY', so exposing this struct using
'IRQ_DOMAIN_HIERARCHY' rather than 'X86_LOCAL_APIC'.
Under the above conditions, if 'HPET_TIMER' is selected, the following
compilation error will occur:
arch/x86/kernel/hpet.c:550:13: error: ‘x86_vector_domain’ undeclared
arch/x86/kernel/hpet.c:600:9: error: implicit declaration of
function ‘init_irq_alloc_info’
This is because 'x86_vector_domain' is defined in 'kernel/apic/vector.c'
which is compiled only when 'X86_LOCAL_APIC' is enabled. Besides,
function 'msi_domain_set_affinity' is defined in 'include/linux/msi.h'
which depends on 'GENERIC_MSI_IRQ'. So use 'X86_LOCAL_APIC' and
'GENERIC_MSI_IRQ' to expose these code.
