2020-01-17target/arm: adjust program counter for wfi exception in AArch32Jeff Kubascik
The wfi instruction can be configured to be trapped by a higher exception level, such as the EL2 hypervisor. When the instruction is trapped, the program counter should contain the address of the wfi instruction that caused the exception. The program counter is adjusted for this in the wfi op helper function. However, this correction is done to env->pc, which only applies to AArch64 mode. For AArch32, the program counter is stored in env->regs[15]. This adds an if-else statement to modify the correct program counter location based on the the current CPU mode.

2020-01-17target/arm/arm-semi: fix SYS_OPEN to return nonzero filehandleMasahiro Yamada
According to the specification "Semihosting for AArch32 and Aarch64", the SYS_OPEN operation should return: - A nonzero handle if the call is successful - -1 if the call is not successful So, it should never return 0. Prior to commit 35e9a0a8ce4b ("target/arm/arm-semi: Make semihosting code hand out its own file descriptors"), the guest fd matched to the host fd. It returned a nonzero handle on success since the fd 0 is already used for stdin. Now that the guest fd is the index of guestfd_array, it starts from 0. I noticed this issue particularly because Trusted Firmware-A built with PLAT=qemu is no longer working. Its io_semihosting driver only handles a positive return value as a valid filehandle. Basically, there are two ways to fix this: - Use (guestfd - 1) as the index of guestfs_arrary. We need to insert increment/decrement to convert the guestfd and the array index back and forth. - Keep using guestfd as the index of guestfs_array. The first entry of guestfs_array is left unused. I thought the latter is simpler. We end up with wasting a small piece of memory for the unused first entry of guestfd_array, but this is probably not a big deal.

2020-01-09semihosting: add qemu_semihosting_console_inc for SYS_READCKeith Packard
Provides a blocking call to read a character from the console using semihosting.chardev, if specified. This takes some careful command line options to use stdio successfully as the serial ports, monitor and semihost all want to use stdio. Here's a sample set of command line options which share stdio between semihost, monitor and serial ports: qemu \ -chardev stdio,mux=on,id=stdio0 \ -serial chardev:stdio0 \ -semihosting-config enable=on,chardev=stdio0 \ -mon chardev=stdio0,mode=readline This creates a chardev hooked to stdio and then connects all of the subsystems to it. A shorter mechanism would be good to hear about.

2020-01-09target/arm: only update pc after semihosting completesAlex Bennée
Before we introduce blocking semihosting calls we need to ensure we can restart the system on semi hosting exception. To be able to do this the EXCP_SEMIHOST operation should be idempotent until it finally completes. Practically this means ensureing we only update the pc after the semihosting call has completed.

2020-01-08ppc/spapr: Support reboot of secure pseries guestBharata B Rao
A pseries guest can be run as a secure guest on Ultravisor-enabled POWER platforms. When such a secure guest is reset, we need to release/reset a few resources both on ultravisor and hypervisor side. This is achieved by invoking this new ioctl KVM_PPC_SVM_OFF from the machine reset path. As part of this ioctl, the secure guest is essentially transitioned back to normal mode so that it can reboot like a regular guest and become secure again. This ioctl has no effect when invoked for a normal guest. If this ioctl fails for a secure guest, the guest is terminated.
