Hi Sinan,
This data structure become some sort of big, any idea to reduce
memory consumption?
Thanks,
Gerry
Hi Gerry,
There are two constants in the code.
#define ACPI_PCI_LINK_MAX_POSSIBLE 16
I changed the data type above. Previously it was consuming 16 bytes now
64 bytes.
The second one is this.
#define ACPI_MAX_IRQS 256
I changed ACPI_MAX_IRQS to 1020 from 256. Let's assume 1024.
I'm concerned about this though since you warned. This used to consume
1024 bytes now 4096 bytes.
static int acpi_irq_penalty[ACPI_MAX_IRQS] = {
PIRQ_PENALTY_ISA_ALWAYS, /* IRQ0 timer */
...
}
