Hello,
There are problems with the Cyclades Cyclom YeP driver. (see PR
i386/30965). I've put printf's in the driver code on several places to
check where the point is of hard locking and its seems to be on line 136
in the /usr/src/sys/pci/cy_pci.c in my situation.
--------<snipped>---------------------------------------------------------------------
case PLX_9050:
outw(ioport + CY_PLX_9050_ICS,
inw(ioport + CY_PLX_9050_ICS) |
CY_PLX_9050_ICS_IENABLE |
CY_PLX_9050_ICS_LOCAL_IENABLE);
--------<snipped>---------------------------------------------------------------------
This particular piece of code is hard-locking a DUAL PENTIUM III 933
DELL PowerEdge 2550 with 2 YeP (PCI) boards with a SINGLE CPU kernel.
(Doesn't even react on numlock key anymore)
I really need some enligtment on this.
Attached my kernel conf file and below the piece of code containg the lines.
static void
cy_attach(config_id, unit)
pcici_t config_id;
int unit;
{
vm_offset_t paddr;
void *vaddr;
u_int32_t ioport;
int adapter;
u_char plx_ver;
ioport = (u_int32_t) pci_conf_read(config_id, CY_PCI_BASE_ADDR1)
& ~0x3;
paddr = pci_conf_read(config_id, CY_PCI_BASE_ADDR2) & ~0xf;
#if 0
if (!pci_map_mem(config_id, CY_PCI_BASE_ADDR2, &vaddr, &paddr)) {
printf("cy%d: couldn't map shared memory\n", unit);
return;
};
#endif
vaddr = pmap_mapdev(paddr, 0x4000);
adapter = cyattach_common(vaddr, 1);
if (adapter < 0) {
/*
* No ports found. Release resources and punt.
*/
printf("cy%d: no ports found!\n", unit);
goto fail;
}
/*
* Allocate our interrupt.
* XXX Using the ISA interrupt handler directly is a bit of a
violation
* since it doesn't actually take the same argument. For
PCI, the
* argument is a void * token, but for ISA it is a unit. Since
* there is no overlap in PCI/ISA unit numbers for this
driver, and
* since the ISA driver must handle the interrupt anyway,
we use
* the unit number as the token even for PCI.
*/
if (
#ifdef CY_PCI_FASTINTR
!pci_map_int_right(config_id, (pci_inthand_t *)cyintr,
(void *)adapter, &tty_imask,
INTR_EXCL | INTR_FAST) &&
#endif
!pci_map_int_right(config_id, (pci_inthand_t *)cyintr,
(void *)adapter, &tty_imask, 0)) {
printf("cy%d: couldn't map interrupt\n", unit);
goto fail;
}
/*
* Enable the "local" interrupt input to generate a
* PCI interrupt.
*/
plx_ver = *((u_char *)vaddr + PLX_VER) & 0x0f;
switch (plx_ver) {
case PLX_9050:
outw(ioport + CY_PLX_9050_ICS,
