The clock comparator and the QEMU timer work the same way, triggering at a given time, they just differ by the origin and the scale. It is therefore possible to go from one to another without using the current clock value. This spares two calls to qemu_clock_get_ns, which probably return slightly different values, possibly reducing the accuracy.

To support dynamically updating the IPL device from inside the KVM guest on the s390 platform, DIAG 308 instruction is intercepted in QEMU to handle the request. Subcode 5 allows to specify a new boot device, which is saved for later in the s390_ipl device. This also allows to switch from an external kernel to a boot device. Subcode 6 retrieves boot device configuration that has been previously set.

Currently, load_normal_reset() and modified_clear_reset() as triggered by a guest vcpu will initiate cpu resets on the current vcpu thread for all cpus. The reset should happen on the individual vcpu thread instead, so let's use run_on_cpu() for this. This avoids calls to synchronize_rcu() in the kernel.

Exploit the new api for userspace-controlled cmma. If supported, enable cmma during kvm initialization and register a reset handler for cmma, which is also called directly from the load IPL code. The reset functionality is needed to reset the cmma state of the guest pages, e.g. if a system reset is triggered via qemu monitor; otherwise this could result in data corruption. A guest triggered reboot may now lead to multiple cmma resets; this is OK, however, as this is slowpath anyway and the simplest way to achieve the intended effects.

kdump on s390 uses a load normal reset to bring the system in a defined state by doing a subsystem reset. The issuing CPUs will have an initial CPU reset, all other CPUs will have a CPU reset as defined in POP (no register content will change). Implement this as architectured.

The function is only used in misc_helper.c, so move it to that file. This reduces the size of debug executables (compiled without optimization) because they get unused code and data for each compilation which includes cpu.h. Executables with optimization don't change their size. ebcdic2ascii is currently unused and could be removed (not done here). The array ascii2ebcdic must be accessed with an unsigned index, therefore (int)ascii[i] was replaced by (uint8_t)ascii[i]. The old code would have failed for a signed char less than 0. The current code only converts "QEMU" and spaces to EBCDIC, so there is no problem today. Signed-off-by: NStefan Weil <sw@weilnetz.de> Signed-off-by: NAlexander Graf <agraf@suse.de>
