2015-06-19target-arm: Do not reset sysregs marked as ALIASSergey Fedorov
cp_reg_reset() is called from g_hash_table_foreach() which does not define a specific ordering of the hash table iteration. Thus doing reset for registers marked as ALIAS would give an ambiguous result when resetvalue is different for original and alias registers. Exit cp_reg_reset() early when passed an alias register. Then clean up alias register definitions from needless resetvalue and resetfn. In particular, this fixes a bug in the handling of the PMCR register, which had different resetvalues for its 32 and 64-bit views.

2015-06-19target-arm: Add the Cortex-M4 CPUAurelio C. Remonda
This patch adds the Cortex-M4 CPU. The M4 is basically the same as the M3, the main differences being the DSP instructions and an optional FPU. Only no-FPU cortex-M4 is implemented here, cortex-M4F is not because the core target-arm code doesn't support the M-profile FPU model yet. Signed-off-by: Aurelio C.

2015-06-19vhost: enable vhost without without MSI-XPankaj Gupta
We use vhostforce to enable vhost even if Guests don't have MSI-X support and we fall back to QEMU virtio-net. This gives a very small performance gain, but the disadvantage is that guest now controls which virtio code is running (qemu or vhost) so our attack surface is doubled. This patch will enable vhost unconditionally whenever it's requested. For compatibility, enable vhost when vhostforce is set, as well.

2015-06-19pci: Don't register a specialized 'config_write' if default behavior is intendedShmulik Ladkani
Few devices have their specialized 'config_write' methods which simply call 'pci_default_write_config' followed by a 'msix_write_config' or 'msi_write_config' calls, using exact same arguments. This is unnecessary as 'pci_default_write_config' already invokes 'msi_write_config' and 'msix_write_config'. Also, since 'pci_default_write_config' is the default 'config_write' handler, we can simply avoid the registration of these specialized versions.

The tb_check_watchpoint function currently assumes that all memory access is done either directly through the TCG code or through an helper which knows its return address. This is obviously wrong as the helpers use cpu_ldxx/stxx_data functions to access the memory. Instead of aborting in that case, don't try to retranslate the code, but assume that the CPU state (and especially the program counter) has been saved before calling the helper. Then invalidate the TB based on this address. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-06-17target-s390x: PER instruction-fetch event supportAurelien Jarno
For the PER instruction-fetch, we can't use the QEMU breakpoint infrastructure as it triggers for a single address and not a full address range, and as it actually stop before the instruction and not before. We therefore call an helper with the just fetched instruction address, which check if the address is within the PER address range. If it is the case, an event is recorded and will be signaled through an exception. Note that we implement here the PER-3 behaviour, that is an invalid opcode is not considered as an instruction fetch. Without PER-3 this behavious is undefined.

For the PER successful-branching event support, we can't rely on any QEMU infrastucture. We therefore call an helper in all places where a branch can be taken. We have to pay attention to the branch to next case, as it's still a taken branch. We don't need to care about the cases using goto_tb, as we have disabled them in the previous patch.

2015-06-17target-s390x: basic PER event handlingAurelien Jarno
This patch add basic support to generate PER exceptions. It adds two fields to the cpu structure to record for the PER address and PER code & ATMID values. When an exception is triggered and a PER event is pending, the two PER values are copied to the lowcore area. At the end of an instruction, an helper is checking for a possible pending PER event and triggers an exception in that case. For that to work with branches, we need to disable TB chaining when PER is activated. Fortunately it's already in the TB flags. Finally in case of a SERVICE CALL exception, we need to trigger the PER exception immediately after. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>
