2014-03-04Introduce dummy console deviceNikunj A Dadhania3-1/+43
Qemu can create console-less machine, aka no output device. And there are dependencies in the guest which expects a valid output device. Add this dummy device that gobbles up all the output send, and keeps the guest happy. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2014-03-04vio-vscsi: Fix CRQ allocation alignmentBenjamin Herrenschmidt1-3/+6
alloc-mem in SLOF does not always return aligned values it seems, so we need to align it manually. While messing around I hit a case where after a close and re-open via the client interface vscsi would fail to initialize without this fix.

2014-02-04Make "boot net:dhcp" boot from IPv4 onlyAvik Sil1-3/+7
The default network boot method "boot net" tries to boot from both IPv4 and IPv6 networks. The "boot net:ipv6" allows to boot from IPv6 network only. But there is no option for booting from IPv4 network only. This patch addresses this issue.

2014-02-04Fix virtio device shutdownAvik Sil2-3/+9
The virtio device shutdown method is called during quiesce in order to reset the device. This implies writing to the I/O region of the device and this only makes sense if the device is opened, otherwise we hit an "unassigned write" handler in qemu. This happens for example while booting a guest from a virtio-blk or virtio-scsi device, when the guest kernel reaches the end of prom_init().

2014-02-04Change shutdown method name for virtio-scsiAvik Sil1-2/+2
add-quiesce-xt adds a different method virtio-scsi-shutdown which is not intended to be added, since the intended method shares the same name with the un-intended one. This makes call to the wrong method with wrong parameter which makes it unable to reset virtion-scsi device during quiesce. This patch fixes this by renaming the method name.

2014-02-04Add support for 64bit LE ABI v1 and v2 supportNikunj A Dadhania6-18/+77
Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com> -- v2: With the parameters changed for go-64, kernel loading from commandline broke v3: (client-exec) calls start-elf64 directly, fix args
2014-02-04Change representation of string environment variableNikunj A Dadhania1-3/+3
Currently strings are stored in the dictionary using "string," which stores the length as a byte. This brings in the limitation of only 255 byte string. The issue got exposed when using "boot-device" which was more than 256 bytes, and the string length was equal to (length & 0xFF) With this patch, we are storing the length in dictionary in a cell and copying the string after that.

2014-01-20Enable seamless netboot on IPv6 networkAvik Sil7-39/+81
To boot from an IPv6 network user has to type "boot net:ipv6" from SLOF prompt. This is inconvenient in auto-install environment. This patch addresses this issue by falling back to IPv6 booting in case IPv4 booting fails (No DHCPv4 response). Signed-off-by: Avik Sil <aviksil@linux.vnet.ibm.com>

2013-12-17Work around missing sc 1 traps on pHypAlexander Graf12-3/+238
When running a pseries guest in PR KVM on top of pHyp, sc 1 instructions are handled directly by pHyp, so we don't get to see them. That means we need to get inventive. Invent a new instruction that behaves like sc 1, but really is a reserved instruction that traps. This instruction can be used by KVM to emulate sc 1 behavior. This patch adds the SLOF support for it. With this, SLOF detects whether it's running on such a broken setup and if so patches itself to execute the fake sc 1 instruction instead of the real one. Furthermore, we also hook into "quiesce" which Linux calls when it boots. This gives us the chance to also patch Linux when it boots up, so it uses the fake sc 1 too.

2013-12-16fix print_version() to return where it came fromAlexander Graf2-6/+3
The print_version() is jumping through hoops to get back to where it was called from, though it actually does get called with "bl" already, so it knows. Just return to where we came from after print_version(), making it a function we can call from other places in the code.

2013-11-22pci-properties: add properties to enable hotplug for spaprqemu-slof-20131122Michael Roth3-0/+17
drmgr expects ibm,my-drc-index and ibm,loc-code OF properties in the corresponding device tree node to determine whether a pre-populated slot is hotpluggable/unpluggable. This is also stated as a boot-time requirement for DR-capable devices in SPAPR, though it does not specify there how these entries are to be generated. In the case of QEMU, hotpluggable slots are allocated entries based on bus/slotno values, so we can determine these entries statically at boot-time, rather than relying on RTAS calls as we would during OS-driven configuration.

2013-11-17Add ipv6 support in net-snkAvik Sil14-53/+2191
This patch adds support for booting from a IPv6 network. It gets the boot information (tftp server, boot file name) from DHCPv6 server or can be specified manually using obp-tftp arguments. To boot from a IPv6 network, type "boot net:ipv6" from the SLOF prompt. To specify ipaddresses manually, type "boot net:ipv6,<si6addr>,<filename>,<ci6addr>" from the SLOF prompt. This patch is based on the IPv6 code written by the former SLOF team. Signed-off-by: Avik Sil <aviksil@linux.vnet.ibm.com>
2013-11-17ipv4: fix frame overwriting following arp_send_requestAvik Sil1-7/+22
Sometimes before ARP request frame is written to the line by qemu, the data gets overwritten by next outgoing frame (typically tftp request) since both use the same ARP table index for the frame buffer. This is fixed by copying the next outgoing packet data to a different buffer instead of writing it to same ARP table index's frame buffer. Signed-off-by: Avik Sil <aviksil@linux.vnet.ibm.com>
