>Description:
When booting 9.0-RELEASE (32bit ppc) on IBM pSeries 610 (7028-6E1), going to SMS, choosing install device CD-ROM, choosing FreeBSD 9.0, it fails with:
Heap memory claim failed!
I traced the source to the following 3 files:
sys/boot/ofw/common/main.c
..
..
48 #define HEAP_SIZE 0x80000
..
52 void
53 init_heap(void)
54 {
55 void *base;
56 ihandle_t stdout;
57
58 if ((base = ofw_alloc_heap(HEAP_SIZE)) == (void *)0xffffffff) {
59 OF_getprop(chosen, "stdout", &stdout, sizeof(stdout));
60 OF_puts(stdout, "Heap memory claim failed!\n");
61 OF_enter();
62 }
63
64 setheap(base, (void *)((int)base + HEAP_SIZE));
65 }
..
..
sys/boot/ofw/libofw/ofw_memory.c
..
..
119 ofw_alloc_heap(unsigned int size)
120 {
121 phandle_t memoryp, root;
122 cell_t available[4];
123 cell_t acells;
124
125 root = OF_finddevice("/");
126 acells = 1;
127 OF_getprop(root, "#address-cells", &acells, sizeof(acells));
128
129 memoryp = OF_instance_to_package(memory);
130 OF_getprop(memoryp, "available", available, sizeof(available));
131
132 heap_base = OF_claim((void *)available[acells-1], size,
133 sizeof(register_t));
134
135 if (heap_base != (void *)-1) {
136 heap_size = size;
137 }
138
139 return (heap_base);
140 }
..
..
sys/boot/ofw/libofw/openfirm.c
..
..
617 /* Claim an area of memory. */
618 void *
619 OF_claim(void *virt, u_int size, u_int align)
620 {
621 static struct {
622 cell_t name;
623 cell_t nargs;
624 cell_t nreturns;
625 cell_t virt;
626 cell_t size;
627 cell_t align;
628 cell_t baseaddr;
629 } args = {
630 (cell_t)"claim",
631 3,
632 1,
633 };
634
635 args.virt = (cell_t)virt;
636 args.size = size;
637 args.align = align;
638 if (openfirmware(&args) == -1)
639 return ((void *)-1);
640 return ((void *)args.baseaddr);
641 }
..
..
I noticed that the NetBSD version only does:
sys/arch/macppc/stand/ofwboot/Locore.c
..
442 return args.baseaddr;
..
>How-To-Repeat:
Boot from FreeBSD 9.0 CD on an IBM 7028-6E1 or 7028-6C1.
