The documentation shows how to use -kernel and friends for booting Linux, but obviously knows nothing about multiboot yet. Let's include some documentation for multiboot, so people know how to fully exploit this cool new feature.

In order to build the multiboot option rom, we need a Makefile and a tool to sign the rom with. Both are provided by this patch and mostly taken from the extboot source, written by Anthony Liguori. Once built, the resulting binary gets copied to pc-bios automatically. Building also occurs automatically when on an x86 host.

This patch implements support for Multiboot on x86 for -kernel. Multiboot is a "new" approach to get rid of different bootloaders, providing a unified interface for the kernel. It supports command line options and kernel modules. The two probably best known projects using multiboot are Xen and GNU Hurd. This implementation should be mostly feature-complete. It is missing VBE extensions, but as no system uses them currently it does not really hurt. To use multiboot, specify the kernel as -kernel option. Modules should be given as -initrd options, seperated by a comma (,). -append also works. Please bear in mind that grub also does gzip decompression, which qemu does not do yet. To run existing images, please ungzip them first. The guest multiboot loader code is implemented as option rom using int 19. Parts of the work are based on efforts by Rene Rebe, who originally ported my code to int 19. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Multiboot passes options to the option rom using the fw_cfg device. Right now, that device is local to the bochs_bios_init function. Let's change that and expose it, so everyone may put data in there. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

For multiboot support, we need bochs_bios_init to happen before load_linux, so we get the fw_cfg device. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

The KVM kernel will disable all bits in CPUID which are not present in the host. As this is mostly true for the hypervisor bit (1.ecx), preserve its value before the trim and restore it afterwards.

KVM provides an in-kernel feature to disable CPUID bits that are not present in the current host. So there is no need here to duplicate this work. Additionally allows 3DNow! on capable processors, since the restriction seems to apply to QEMU/TCG only.

If we want to trim the user provided CPUID bits for KVM to be not greater than that of the host, we should not remove the bits _after_ we sent them to the kernel. This fixes the masking of features that are not present on the host by moving the trim function and it's call from helper.c to kvm.c. It helps to use -cpu host.

Although the guest's CPUID bits can be controlled in a fine grained way in QEMU, a simple way to inject the host CPU is missing. This is handy for KVM desktop virtualization, where one wants the guest to support the full host feature set. Introduce another CPU type called 'host', which will propagate the host's CPUID bits to the guest. Unwanted bits can still be turned off by using the existing syntax (-cpu host,-skinit) Signed-off-by: NAndre Przywara <andre.przywara@amd.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

KVM defaults to the hypervisor CPUID bit to be set, whereas pure QEMU clears it. On some occasions one wants to set or clear it the other way round (for instance to get HyperV running inside a guest). Move the bit-set to be done before the command line parsing and enable it by default. One can disable it by using: -cpu qemu64,-hypervisor Fix some whitespace damage on the way.

Problem: It is impossible to feed filenames with the character colon because qemu interprets such names as a protocol. For example filename scsi:0, is interpreted as a protocol by name "scsi". This patch allows user to espace colon characters. For example the above filename can now be expressed either as 'scsi\:0' or as file:scsi:0 anything following the "file:" tag is interpreted verbatin. However if "file:" tag is omitted then any colon characters in the string must be escaped using backslash. Here are couple of examples: scsi\:0\:abc is a local file scsi:0:abc http\://myweb is a local file by name http://myweb file:scsi:0:abc is a local file scsi:0:abc file:http://myweb is a local file by name http://mywebSigned-off-by: NRam Pai <linuxram@us.ibm.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Push the smb state, smb_dir, into SlirpState and construct it in a way that allows multiple smb instances (one per slirp stack). Remove the smb directory on slirp cleanup instead of qemu termination.

Once again this was a long journey to reach the destination: Allow to instantiate slirp multiple times. But as in the past, the journey was worthwhile, cleaning up, fixing and enhancing various parts of the user space network stack along the way. What is this particular change good for? Multiple slirps instances allow separated user space networks for guests with multiple NICs. This is already possible, but without any slirp support for the second network, ie. without a chance to talk to that network from the host via IP. We have a legacy guest system here that benefits from this slirp enhancement, allowing us to run both of its NICs purely over unprivileged user space IP stacks. Another benefit of this patch is that it simply removes an artificial restriction of the configuration space qemu is providing, avoiding another source of surprises that users may face when playing with possible setups.

The essence of this patch is to stuff (almost) all global variables of the slirp stack into the structure Slirp. In this step, we still keep the structure as global variable, directly accessible by the whole stack. Changes to the external interface of slirp will be applied in the following patches.

Currently, ip_id is always initialized to 0 on slirp startup (despite the broken attempt to derive it from the clock). This is good for reproducibility. But it is not preserved across save/restore.
