2012-04-15pseries: Fix reset of VIO network deviceDavid Gibson1-3/+11
Currently, the PAPR VIO network device does not have a reset handler. This means that after a hard reset, H_REGISTER_LOGICAL_LAN will return an error when the new guest boot attempts to initialize the device. This patch corrects this, adding a suitable reset hook.

2012-04-15pseries: Correctly use the device model reset hooksDavid Gibson2-4/+9
Recently we added code to properly clean away VIO CRQs on reset However, this directly uses qemu_register, rather than the existing device model reset callbacks. This patch cleans this up by adding proper use of the reset hook to the VIO bus model. The existing CRQ reset code is converted to the new method.

2012-04-15pseries: Remove old hcalls hook stubDavid Gibson1-1/+0
Some time ago we removed all use of the 'hcalls' callback in the pseries VIO code, which was used to workaround an ordering problem which has since been solved properly. However, the function pointer for the hook remains. This patch cleans it away. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Andreas Färber <afaerber@suse.de>

2012-04-15pseries: Fix RTAS based config accessDavid Gibson1-38/+79
On the pseries platform, access to PCI config space is via RTAS calls( which go to the hypervisor) rather than MMIO. This means we don't use the same code path as nearly everyone else which goes through pci_host.c and we're missing some of the parameter checking along the way. We do have some parameter checking in the RTAS calls, but it's not enough. It checks for overruns, but does not check for unaligned accesses, oversized accesses (which means the guest could trigger an assertion failure from pci_host_config_{read,write}_common(). Worse it doesn't do the basic checking for the number of RTAS arguments and results before accessing them. This patch fixes these bugs. Cc: Michael S.

2012-04-15target-ppc: Add hooks for handling tcg and kvm limitationsDavid Gibson4-25/+54
On target-ppc, our table of CPU types and features encodes the features as found on the hardware, regardless of whether these features are actually usable under TCG or KVM. We already have cases where the information from the cpu table must be fixed up to account for limitations in the emulation method we're using. e.g. TCG does not support the DFP and VSX instructions and KVM needs different numbering of the CPUs in order to tell it the correct thread to core mappings. This patch cleans up these hacks to handle emulation limitations by consolidating them into a pair of functions specifically for the purpose.

2012-04-15pseries: Consolidate hack for RTAS display-character usageDavid Gibson3-5/+3
Currently the pseries machine contains not one but two somewhat ugly hacks to allow printing of early debug messages before the guest has properly read the device tree. First, we special case H_PUT_TERM_CHAR so that a vtermno of 0 (usually invalid) will look for a suitable vty and use that. This supports Linux's early debug code which will use H_PUT_TERM_CHAR with vtermno==0 before reading the device tree. Second, we support the RTAS display-character call. This takes no vtermno so we assume the address of the default first VTY. This patch makes things more consistent by folding the second hack into the first. Now, display-character uses the existing vty_lookup() function to do the same search for a suitable VTY.

2012-04-15pseries: Fix bug with reset of VIO CRQsDavid Gibson1-8/+25

2012-04-15PPC: Fix TLB invalidation bug within the PPC interrupt handler.Mark Cave-Ayland1-1/+1
Commit 41557447d30eeb944e42069513df13585f5e6c7f also introduced a subtle TLB flush bug. By applying a mask to the interrupt MSR which cleared the IR/DR bits at the start of the interrupt handler, the logic towards the end of the handler to force a TLB flush if either one of these bits were set would never be triggered. This patch simply changes the IR/DR bit check in the TLB flush logic to use the original MSR value (albeit with some interrupt-specific bits cleared) so that the IR/DR bits are preserved at the point where the check takes place.

2012-04-14target-xtensa: fix tb invalidation for IBREAK and LOOPMax Filippov2-11/+20
Instruction breakpoint/zero overhead loop handling code is built into TBs pointed to by IBREAKA/LEND SRs. When these or related SRs get changed TBs at virtual addresses corresponding to their old and their new values must be invalidated. Virtual address range is passed to the tb_invalidate_phys_page_range, which is incorrect in system emulation mode. To fix it use guest TLB/MMU to translate virtual address to physical address. However the guest may not have virtual-to-physical mapping at the moment of IBREAKA/LEND change, thus this fix is not 100% accurate.
