On PPC, the default PAGE_SIZE is 64kb. Unfortunately, the hardware alignments don't match here: There are RAM and MMIO regions within a single page when it's 64kb in size. So the only way out for now is to tell the user that he should use 4k PAGE_SIZE. This patch gives the user a hint on that, telling him that failing to register a prefix slot is most likely to be caused by mismatching PAGE_SIZE. This way it's also more future-proof, as bigger PAGE_SIZE can easily be supported by other machines then, as long as they stick to 64kb granularities. Signed-off-by: NAlexander Graf <agraf@suse.de>

When compiling Qemu with older kernel headers, the PVR setting mechanism isn't available yet. Unfortunately, back then I didn't add a capability we could check against, so all we can do is add a configure test to see if we support PVR setting. For BookE, we don't care yet. This fixes compilation errors with KVM enabled on older kernel headers (like 2.6.32). Signed-off-by: NAlexander Graf <agraf@suse.de>

Classic/server ppc has had SREGS for a while now (though I think not always?), but it's still missing for booke. Check the capability before calling KVM_SET_SREGS. Without this, booke kvm fails to boot as of commit 84b4915d (kvm: Handle kvm_init_vcpu errors). Also, don't write random stack state into the non-PVR sregs fields -- have kvm fill it in first. Eventually booke will have sregs and it will have its own capability to be tested here. However, we will want a way for platform code to request to look like the actual CPU we're running on, especially if SoC devices are being directly assigned.

Currently the qemu pseries machine numbers its virtual serial devices from 0. However, existing pSeries machines running pHyp number them from 0x30000000. In theory these indices are arbitrary, since everything necessary for the kernel to find them is advertised in the device tree. However the debian installer, at least, incorrectly looks for a device named vty@30... to determine whether to use the hypervisor console. Therefore this patch moves the numbers we use to match the existing pHyp practice, in order to workaround broken userspace apps of this type.

Currently, the qemu emulated pseries machine puts "qemu,emulated-pSeries-LPAR" in the device tree's root level 'model' property. Unfortunately this confuses some installers and ybin, which expect this to start with "IBM" on pSeries machines. This patch addresses this problem, making the property more closely resemble the pattern of existing real hardware.

The original pSeries machine was limited to 32 CPUs, more or less arbitrarily. Particularly when we get SMT KVM guests it will be pretty easy to exceed this. Therefore, raise the max number of CPUs in a pseries machine guest to 256.

Prototype without "inline" keyword breaks the build with some gcc versions. Noticed by Alexander Graf. Fix this by removing the inline keywork everywhere. Some functions can't be inlined anyway as the are referenced using function pointers. Beside that gcc does a pretty good job on auto-inlining these days.

This mask contains all of the bits that should be ignored while single stepping in the debugger. The mask contains 2 bits that are not currently cleared, but are also never set.

These defines will be place-holders for cpu-specific functionality. Generic code will, at the end of the patch series, no longer have to concern itself about how SMI, NMI, etc should be handled.

When we're trying to get a newly registered phys memory client updated with the current page mappings, we end up passing the region offset (a ram_addr_t) as the start address rather than the actual guest physical memory address (target_phys_addr_t). If your guest has less than 3.5G of memory, these are coincidentally the same thing. If there's more, the region offset for the memory above 4G starts over at 0, so the set_memory client will overwrite it's lower memory entries. Instead, keep track of the guest phsyical address as we're walking the tables and pass that to the set_memory client.

When we register a physical memory client, we try to walk the page tables, calling the set_memory hook for every entry. Effectively playing catchup for the client for everything already registered. With this type, we only walk the 2nd entry of the l1 table, typically missing all of the registered memory. Signed-off-by: NAlex Williamson <alex.williamson@redhat.com> Signed-off-by: NMichael S.

Like other Intel devices, e100 (eepro100) uses little endian byte order. This patch was tested with these combinations: i386 host, i386 + mipsel guests (le-le) mipsel host, i386 guest (le-le) i386 host, mips + ppc guests (le-be) mips host, i386 guest (be-le) mips and mipsel hosts were emulated machines. v2: Use prefix for new functions. Add the same prefix to stl_le_phys. Fix alignment of mem (needed for word/dword reads/writes). Signed-off-by: NStefan Weil <weil@mail.berlios.de> Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

QEMU sends frames smaller than 60 bytes to ethernet nics. Such frames are rejected by real NICs and their emulations. To avoid this behaviour, other NIC emulations pad received frames. This patch enables this workaround for eepro100, too. All related code is marked with CONFIG_PAD_RECEIVED_FRAMES, so we can drop this in case QEMU's networking code is ever changed.
