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.

It's already possible to do a network boot of an s390x guest with an
external netboot image based on a Linux installation, but it would
be much more convenient if the s390-ccw firmware supported network
booting right out of the box, without the need to assemble such an
external image first.
This is an s390-netboot.img that can be used for network booting.
You can download a combined kernel + initrd image via TFTP
by starting QEMU for example with:
qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \
-netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img
Note that this version does not support downloading via config
files (i.e. pxelinux config files or .INS config files) yet. This
will be added later.

Now that we've read all the possible limits that have been defined for
a virtio-scsi controller and the disk we're booting from, it's possible
that we are STILL going to exceed the limits of the host device.
For example, a "-device scsi-generic" device does not support the
Block Limits VPD page.
So, let's fallback to something that seems to work for most boot
configurations if larger values were specified (including if nothing
was explicitly specified, and we took default values).

The "Block Limits" Inquiry VPD page is optional for any SCSI device,
but if it's supported it provides a hint of the maximum I/O transfer
length for this particular device. If this page is supported by the
disk, let's issue that Inquiry and use the minimum of it and the
SCSI controller limit. That will cover this scenario:
qemu-system-s390x ...
-device virtio-scsi-ccw,id=scsi0,max_sectors=32768 ...
-drive file=/dev/sda,if=none,id=drive0,format=raw ...
-device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,
drive=drive0,id=disk0,max_io_size=1048576
controller: 32768 sectors x 512 bytes/sector = 16777216 bytes
disk: 1048576 bytes
Now that we have a limit for a virtio-scsi disk, compare that with the
limit for the virtio-scsi controller when we actually build the I/O.
The minimum of these two limits should be the one we use.

The "Supported Pages" Inquiry EVPD page is mandatory for all SCSI devices,

Let's issue this Inquiry, and dump that list with the debug facility.

If we want to issue any of the SCSI Inquiry EVPD pages,
which we do, we could use this function to issue both types
of commands with a little bit of refactoring.

A virtio-scsi request that goes through the host sd driver and exceeds
the maximum transfer size is automatically broken up for us. But the
equivalent request going to the sg driver presumes that any length
requirements have already been honored.
Let's use the max_sectors field on the virtio-scsi controller device,
and break up all requests (both sd and sg) to avoid this problem.

When using virtio-scsi, we multiply the READ(10) data_size by
a block factor twice when building the I/O. This is fine,
since it's only 1 for SCSI disks, but let's clean it up.

The LOADPARM value is fetched from SCP Read Info, but it's applied
only at the phase of bootmap interpretation. So let's read the LOARPARM
value and store it. Also provide a parsing function to detect numbers in
the LOADPARM which can be used during bootmap interpretation.
