commit 91d041c2cf9a3f289efde748a1c2a2d6b908b44a
Author: Damien Zammit <[email protected]>
Date: Tue Oct 14 07:54:34 2025 +0000
irq: Add irqgetstat device status IRQGETPICMODE flavor
This allows reading irq device status 0 for the mode of the interrupt
controller, pic or apic.
TESTED using:
```
\#include <stdio.h>
\#include <device/device.h>
\#include <hurd.h>
\#include <mach.h>
int main()
{
mach_port_t devices, irq;
int pic_mode, cnt = 1;
int err;
err = get_privileged_ports(NULL, &devices);
if (err)
return 1;
err = device_open(devices, D_READ, "irq", &irq);
if (err)
return 2;
err = device_get_status(irq, 0, &pic_mode, &cnt);
if (err)
return 3;
printf("pic_mode = %d\n", pic_mode);
return 0;
}
```
amd64-apic $ sudo ./test
pic_mode = 1
i386-pic $ sudo ./test
pic_mode = 0
i386-apic $ sudo ./test
pic_mode = 1
