Hi Tom,
Which build are you using?
Please take a look at PSARC/2007/453 MSI-X interrupt limit override.
Thanks,

Hi,
I am using ddi_intr_alloc to allocate MSIX interrupt handles, I am
requesting 9, however, why the actual number is always 2 on both Sparc and
x86 machines?
intr_type=DDI_INTR_TYPE_MSIX;
/*
* Get number of supported interrupts
*/
rc = ddi_intr_get_nintrs(devinfo, intr_type, &count);
/*
* Get number of available interrupts
*/
rc = ddi_intr_get_navail(devinfo, intr_type, &avail);
request=9;
rc = ddi_intr_alloc(devinfo, qlge->htable, intr_type, 0,
request, &actual, DDI_INTR_ALLOC_NORMAL);
why the actual is always 2?
Tom
