2017-03-14resume: Don't attempt to use generic reboot mechanisms on QEMUKevin O'Connor5-5/+18
On QEMU it's necessary to manually reset the BIOS memory region between 0xc0000-0x100000 on a reboot. After this manual memory reset is completed, it's not valid to use the generic reset mechanisms. Rename qemu_prep_reset() to qemu_reboot() and change the function to immediately reboot after the code memcpy. This fixes a bug that could cause code corruption on reboots - calling the udelay() function (as invoked by i8042_reboot and/or pci_reboot) was not valid after the BIOS was memcpy'd.

2017-02-24QEMU fw_cfg: Add functions for accessing files by keyBen Warren2-11/+32
Due to memory contraints, when resuming from S3 the fw_cfg "files" API isn't available. This adds a simple API to get a file 'key', and to write to the file using the key as a reference.

2017-02-24ps2port: Disable keyboard/mouse prior to resetting ps2 controllerKevin O'Connor1-1/+12
If one of the ps2 ports is enabled prior to the ps2 controller reset then it is possible a device event (eg, key press or mouse move) could be mistaken for the controller reset response code. This would result in a failure and the keyboard would be disabled during the boot. Always disabling the keyboard and mouse prior to reset ensures that the controller reset return code can be read properly.

2017-02-24vgasrc: Increase debug levelPaul Menzel1-1/+1
You only want this information for debugging. As it also slows down the boot considerably, as, for example, for every character of the GRUB menu, something is sent over the serial console.

2016-10-25support booting with more than 255 CPUsIgor Mammedov2-4/+21
SDM[*1] says that if there are CPUs with APIC ID greater than 254, BIOS is to pass control to OS in x2APIC mode. Use the fact that QEMU passes in "etc/max-cpus" max possible "APIC ID + 1" to detect need for x2APIC mode. Also instead of CMOS_BIOS_SMP_COUNT which is limited to 256 CPUs use a new rom file "etc/boot-cpus" that QEMU supporting more than 256 CPUs will provide. *1) SDM: Volume 3: EXTENDED XAPIC (X2APIC): Initialization by System Software Signed-off-by: Igor Mammedov <imammedo@redhat.com>
