2010-03-04Makefile: Fix names of GPXE ROM filesStefan Weil
da51e79b7ff2126cc2448749d657a4f6e3b1270f added two new ROM files and removed an old one for eepro100.c. These changes were missing in Makefile (which resulted in a broken "make install"). Reported by Lucas Meneghel Rodrigues, thanks. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-03-04x86: Extend validity of bsp_to_cpuJan Kiszka
As we hard-wire the BSP to CPU 0 anyway and cpuid_apic_id equals cpu_index, bsp_to_cpu can also be based on the latter directly. This will help an early user of it: KVM while initializing mp_state.

2010-03-04KVM: x86: Restrict writeback of VCPU stateJan Kiszka
Do not write nmi_pending, sipi_vector, and mpstate unless we at least go through a reset. And TSC as well as KVM wallclocks should only be written on full sync, otherwise we risk to drop some time on state read-modify-write.

2010-03-04KVM: Rework VCPU state writeback APIJan Kiszka
This grand cleanup drops all reset and vmsave/load related synchronization points in favor of four(!) generic hooks: - cpu_synchronize_all_states in qemu_savevm_state_complete (initial sync from kernel before vmsave) - cpu_synchronize_all_post_init in qemu_loadvm_state (writeback after vmload) - cpu_synchronize_all_post_init in main after machine init - cpu_synchronize_all_post_reset in qemu_system_reset (writeback after system reset) These writeback points + the existing one of VCPU exec after cpu_synchronize_state map on three levels of writeback: - KVM_PUT_RUNTIME_STATE (during runtime, other VCPUs continue to run) - KVM_PUT_RESET_STATE (on synchronous system reset, all VCPUs stopped) - KVM_PUT_FULL_STATE (on init or vmload, all VCPUs stopped as well) This level is passed to the arch-specific VCPU state writing function that will decide which concrete substates need to be written. That way, no writer of load, save or reset functions that interact with in-kernel KVM states will ever have to worry about synchronization again. That also means that a lot of reasons for races, segfaults and deadlocks are eliminated. cpu_synchronize_state remains untouched, just as Anthony suggested. We continue to need it before reading or writing of VCPU states that are also tracked by in-kernel KVM subsystems. Consequently, this patch removes many cpu_synchronize_state calls that are now redundant, just like remaining explicit register syncs.

2010-03-04KVM: Rework of guest debug state writingJan Kiszka
So far we synchronized any dirty VCPU state back into the kernel before updating the guest debug state. This was a tribute to a deficite in x86 kernels before 2.6.33. But as this is an arch-dependent issue, it is better handle in the x86 part of KVM and remove the writeback point for generic code. This also avoids overwriting the flushed state later on if user space decides to change some more registers before resuming the guest. We furthermore need to reinject guest exceptions via the appropriate mechanism. That is KVM_SET_GUEST_DEBUG for older kernels and KVM_SET_VCPU_EVENTS for recent ones. Using both mechanisms at the same time will cause state corruptions. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-03-04Add option to use file backed guest memoryMarcelo Tosatti
Port qemu-kvm's -mem-path and -mem-prealloc options. These are useful for backing guest memory with huge pages via hugetlbfs. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> CC: john cooper <john.cooper@redhat.com>
2010-03-04Allocate memory below 4GB as one chunkAvi Kivity
Instead of allocating a separate chunk for the first 640KB and another for 1MB+, allocate one large chunk. This plays well in terms of alignment and size with large pages. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2010-03-03eepro100: Use tx.statusStefan Weil

2010-03-03eepro100: Use symbolic names and BIT macros in binary operationsStefan Weil
Instead of magic numbers like 0x8000, symbolic names are used for the SCB command and status bits. There are too many configuration bits to use symbolic names there, too. Using the BIT macro is a little help when comparing code and documentation. For the same reason, some other constants were replaced by the BITS macro.

2010-03-03eepro100: Support gpxe boot for all eepro100 devicesStefan Weil
Only two boot ROM files are needed for all devices. * Add these GPXE ROM files using new naming convention (as discussed on qemu-devel). Both files were created with http://rom-o-matic.net/, PCI vendor / device ids as in ROM filenames and option BANNER_TIMEOUT = 0. * Remove old PXE ROM file for i82559er. It was replaced by gpxe-eepro100-80861209.rom. * Update pc-bios/README (and sort entries). Full support still needs additional eepro100 fixes.

2010-03-03eepro100: Fix PXE bootStefan Weil

Hello, There is a small incoherency in curses_keys.h, which makes it fail to emit \n when using e.g. -k fr: curses2keysym transforms \r and 0x157 into \n, but name2keysym binds \r with Return, not \n.

2010-02-28target-i386: fix crash on x86 32bit linux host with hw breakpoint exceptionsJason Wessel
If you make use of hw breakpoints on a 32bit x86 linux host, qemu will segmentation fault when processing the exception. The problem is that the value of env is stored in $ebp in the op_helper raise_exception() function, and it can have the wrong value when calling it from non generated code. It is possible to work around the problem by restoring the value of env before calling raise_exception() using a new helper function that takes (CPUState *) as one of the arguments.

2010-02-28target-alpha: Implement IEEE FP qualifiers.Richard Henderson
IEEE FP instructions are split up so that the rounding mode coming from the instruction and exceptions (both masking and delivery) are handled external to the base FP operation. FP exceptions are properly raised for non-finite inputs to instructions that do not indicate software completion. A shortcut is applied if CONFIG_SOFTFLOAT_INLINE is defined at the top of translate.c: data is loaded and stored into FP_STATUS directly instead of using the functional interface defined by "softfloat.h".
