The current timeout is set to only three seconds - and considering that
vring_wait_reply() or rather get_second() is not doing any rounding,
the real timeout is likely rather 2 seconds in most cases. When the
host is really badly loaded, it's possible that we hit this timeout by
mistake; it's even more likely if we run the guest in TCG mode instead
of KVM.
So let's increase the timeout to 30 seconds instead to ease this situation
(30 seconds is also the timeout that is used by the Linux SCSI subsystem
for example, so this seems to be a sane value for block IO timeout).

If no boot menu options are present, then flag the boot menu to
use the zipl options that were set in the zipl configuration file
(and stored on disk by zipl). These options are found at some
offset prior to the start of the zipl boot menu banner. The zipl
timeout value is limited to a 16-bit unsigned integer and stored
as seconds, so we take care to convert it to milliseconds in order
to conform to the rest of the boot menu functionality. This is
limited to CCW devices.
For reference, the zipl configuration file uses the following
fields in the menu section:
prompt=1 enable the boot menu
timeout=X set the timeout to X seconds
To explicitly disregard any boot menu options, then menu=off or
<bootmenu enable='no' ... /> must be specified.

It is possible while waiting for multiple types of external
interrupts that we might have pending irqs remaining between
irq consumption and irq-type disabling. Those interrupts
could potentially propagate to the guest after IPL completes
and cause unwanted behavior.
As it is today, the SCLP will only recognize write events that
are enabled by the control program's send and receive masks. To
limit the window for, and prevent further irqs from, ASCII
console events (specifically keystrokes), we should only enable
the control program's receive mask when we need it.
While we're at it, remove assignment of the (non control program)
send and receive masks, as those are actually set by the SCLP.

Please choose (default will boot in 10 seconds):
Correct input will boot the respective boot index. If the

The s390-ccw firmware needs some information in support of the
boot process which is not available on the native machine.
Examples are the netboot firmware load address and now the
boot menu parameters.
While storing that data in unused fields of the IPL parameter block
works, that approach could create problems if the parameter block
definition should change in the future. Because then a guest could
overwrite these fields using the set IPLB diagnose.
In fact the data in question is of more global nature and not really
tied to an IPL device, so separating it is rather logical.
This commit introduces a new structure to hold firmware relevant
IPL parameters set by QEMU. The data is stored at location 204 (dec)
and can contain up to 7 32-bit words. This area is available to
programming in the z/Architecture Principles of Operation and
can thus safely be used by the firmware until the IPL has completed.

- pc-bios/s390-ccw: Fix problem with invalid virtio-scsi LUN when rebooting
Signed-off-by: Cornelia Huck <cohuck@redhat.com>
When rebooting a guest that has a virtio-scsi disk, the s390-ccw
bios sometimes bails out with an error message like this:
! SCSI cannot report LUNs: STATUS=02 RSPN=70 KEY=05 CODE=25 QLFR=00, sure !
Enabling the scsi_req* tracing in QEMU shows that the ccw bios is
trying to execute the REPORT LUNS SCSI command with a LUN != 0, and
this causes the SCSI command to fail.
Looks like we neither clear the BSS of the s390-ccw bios during reboot,
nor do we explicitly set the default_scsi_device.lun value to 0, so
this variable can contain random values from the OS after the reboot.
By setting this variable explicitly to 0, the problem is fixed and
the reboots always succeed.

The sclp console in the s390 bios writes raw data,
leading console emulators (such as virsh console) to
treat a new line ('\n') as just a new line instead
of as a Unix line feed. Because of this, output
appears in a "stair case" pattern.
Let's print \r\n on every occurrence of a new line
in the string passed to write to amend this issue.
This is in sync with the guest Linux code in
drivers/s390/char/sclp_vt220.c which also does a line feed
conversion in the console part of the driver.
This fixes the s390-ccw and s390-netboot output like

This patch updates the sun4u model to being much closer to a real Ultra 5
by moving devices behind the 2 simba PCI bridges (A and B) as found on real
hardware.
The most noticeable change introduced by this patchset is that in-built devices
are no longer attached to the PCI root bus, but instead behind PCI bridge A.
Along with this the interrupt routing is updated accordingly to match the
official documentation.
Since the existing code currently bypasses the PCI bridge interrupt
swizzling, the interrupt mapping functions are reorganised so that
pci_pbm_map_irq() is used by the PCI bridges and pci_apb_map_irq() is
used by the PCI host bridge.
Behind the sabre PCI host bridge, the PCI IO space now needs to be
split into two separate halves at 0x8000000. Therefore we also setup a new
PCI IO space region of increased size on the PCI host bridge and enable
32-bit PCI IO accesses to allow IO accesses to reach devices behind PCI
bridge B correctly.
As part of this change we also combine the onboard sunhme NIC and the ebus
into a single multi-function device as done on a real Ultra 5. For other
NICs the existing behaviour is preserved, i.e. we initialise them and
place them into the next free slot on PCI bus B.
Finally we mark the physically unavailable slots (plus slot 0 in busA) as
reserved to ensure that users can't plug devices into non-existent slots
which will break interrupt routing.
Note: since this commit changes PCI topology and interrupt routing, an
updated openbios-sparc64 binary is included with this commit containing the
associated changes to maintain bisectability.
