Replying to [comment:18 korli]:
> The expected log "ht msi mapping enabled" isn't showing up. This could
mean this mapping is already enabled though.
Seems it is:
{{{
KERN: ====== inside pci_enable_msi()
KERN: ***** inside pci_ht_msi_map( 4276092928 )
KERN: info->ht_mapping_capable = 1
KERN: enabled=1
KERN: msi enabled: 0x0081 (ttcdr build)
}}}
The code path does not enter inside the if(), as per my brute-force
tracing:
{{{
pci_ht_msi_map(PCIDev *device, uint64 address)
{
dprintf("***** inside pci_ht_msi_map( %Ld )\n", address);
ht_mapping_info *info = &device->arch_info.ht_mapping;
dprintf("info->ht_mapping_capable = %d\n", info->ht_mapping_capable);
if (!info->ht_mapping_capable)
return;
bool enabled = (info->control_value & PCI_ht_command_msi_enable)
!= 0;
dprintf("enabled=%d\n", enabled);
if ((address != 0) != enabled) {
dprintf(" ..if\n");
if (enabled) {
dprintf(" .. if enabled\n");
info->control_value &= ~PCI_ht_command_msi_enable;
} else {
dprintf(" .. else (with info->address_value=0x%Lx)\n",
info->address_value);
if ((address >> 20) != (info->address_value >>
20))
return;
dprintf("ht msi mapping enabled\n");
}}}
As a side node, I'm seeing something that was not there before, the
rtl81xx driver output is now intertwined with mtrr lines; probably means
nothing though:
{{{
KERN: [rtl81xx] (re) Using 1 MSI message
KERN: mtrr: 0: base: 0x90000, size: 0x10000, type: 0
KERN: [rtl81xx] (re) bus_alloc_resource(1, [1], 0x0, 0xffffffff, 0x1,0x2)
KERN: mtrr: 1: base: 0xa0000, size: 0x20000, type: 0
}}}
