2022-10-27openrisc: re-randomize rng-seed on rebootJason A. Donenfeld1-0/+3
When the system reboots, the rng-seed that the FDT has should be re-randomized, so that the new boot gets a new seed. Since the FDT is in the ROM region at this point, we add a hook right after the ROM has been added, so that we have a pointer to that copy of the FDT.

2022-09-04hw/openrisc: Initialize timer time at startupStafford Horne1-1/+21
The last_clk time was initialized at zero, this means when we calculate the first delta we will calculate 0 vs current time which could cause unnecessary hops. This patch moves timer initialization to the cpu reset. There are two resets registered here: 1. Per cpu timer mask (ttmr) reset. 2. Global cpu timer (last_clk and ttcr) reset, attached to the first cpu only. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Stafford Horne <shorne@gmail.com>

This patch adds the OpenRISC virtual machine 'virt' for OpenRISC. This platform allows for a convenient CI platform for toolchain, software ports and the OpenRISC linux kernel port. Much of this has been sourced from the m68k and riscv virt platforms. The platform provides: - OpenRISC SMP with up to 4 cpus - A virtio bus with up to 8 devices - Standard ns16550a serial - Goldfish RTC - SiFive TEST device for poweroff and reboot - Generated Device Tree to automatically configure the guest kernel Signed-off-by: Stafford Horne <shorne@gmail.com>

Currently the OpenRISC SMP configuration only supports 2 cores due to the UART IRQ routing being limited to 2 cores. As was done in commit 1eeffbeb11 ("hw/openrisc/openrisc_sim: Use IRQ splitter when connecting IRQ to multiple CPUs") we can use a splitter to wire more than 2 CPUs.

2020-12-15target/openrisc: Move pic_cpu code into CPU object properPeter Maydell3-64/+2
The openrisc code uses an old style of interrupt handling, where a separate standalone set of qemu_irqs invoke a function openrisc_pic_cpu_handler() which signals the interrupt to the CPU proper by directly calling cpu_interrupt() and cpu_reset_interrupt(). Because CPU objects now inherit (indirectly) from TYPE_DEVICE, they can have GPIO input lines themselves, and the neater modern way to implement this is to simply have the CPU object itself provide the input IRQ lines. Create GPIO inputs to the OpenRISC CPU object, and make the only user of cpu_openrisc_pic_init() wire up directly to those instead. This allows us to delete the hw/openrisc/pic_cpu.c file entirely. This fixes a trivial memory leak reported by Coverity of the IRQs allocated in cpu_openrisc_pic_init().

2020-01-29hw/core/loader: Let load_elf() populate a field with CPU-specific flagsAleksandar Markovic1-1/+1
While loading the executable, some platforms (like AVR) need to detect CPU type that executable is built for - and, with this patch, this is enabled by reading the field 'e_flags' of the ELF header of the executable in question. The change expands functionality of the following functions: - load_elf() - load_elf_as() - load_elf_ram() - load_elf_ram_sym() The argument added to these functions is called 'pflags' and is of type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word' being the type of the field 'e_flags', in both 32-bit and 64-bit variants of ELF header). Callers are allowed to pass NULL as that argument, and in such case no lookup to the field 'e_flags' will happen, and no information will be returned, of course.

2019-02-05elf: Add optional function ptr to load_elf() to parse ELF notesLiam Merwick1-1/+1
This patch adds an optional function pointer, 'elf_note_fn', to load_elf() which causes load_elf() to additionally parse any ELF program headers of type PT_NOTE and check to see if the ELF Note is of the type specified by the 'translate_opaque' arg. If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.

2017-10-21openrisc: Initial SMP supportStafford Horne1-23/+65
Wire in ompic and add basic support for SMP. The OpenRISC is special in that interrupts for devices are routed to each core's PIC. This is achieved using the qemu_irq_split utility, but this currently limits OpenRISC to 2 cores. This models the reference architecture described in the OpenRISC spec 1.2 proposal. https://github.com/stffrdhrn/doc/raw/arch-1.2-proposal/openrisc-arch-1.2-rev0.pdf The changes to the intialization of the sim include: CPU Reset o Reset each cpu to the bootstrap PC rather than only a single cpu as done before. o During Kernel loading the bootstrap PC is saved in a static global. Network Initialization o Connect the interrupt to each CPU o Use more simple sysbus_mmio_map() rather than memory_region_add_subregion() Sim Initialization o Initialize the pic and tick timer per cpu o Wire in the OMPIC if SMP is enabled o Wire the serial irq to each CPU using qemu_irq_split() Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Stafford Horne <shorne@gmail.com>
2017-10-21openrisc/cputimer: Perparation for MulticoreStafford Horne1-15/+47
In order to support multicore system we move some of the previously static state variables into the state of each core. On the other hand in order to allow timers to be synced between each code the ttcr (tick timer count register) is moved out of the core. This is not as per real hardware spec which has a separate timer counter per core, but it seems the most simple way to keep each clock in sync.

2017-09-19cpu: make cpu_generic_init() abort QEMU on errorIgor Mammedov1-4/+0
Almost every user of cpu_generic_init() checks for returned NULL and then reports failure in a custom way and aborts process. Some users assume that call can't fail and don't check for failure, though they should have checked for it. In either cases cpu_generic_init() failure is fatal, so instead of checking for failure and reporting it various ways, make cpu_generic_init() report errors in consistent way and terminate QEMU on failure.

2017-05-04target/openrisc: Support non-busy idle state using PMR SPRStafford Horne1-0/+1
The OpenRISC architecture has the Power Management Register (PMR) special purpose register to manage cpu power states. The interesting modes are: * Doze Mode (DME) - Stop cpu except timer & pic - wake on interrupt * Sleep Mode (SME) - Stop cpu and all units - wake on interrupt * Suspend Model (SUME) - Stop cpu and all units - wake on reset The linux kernel will set DME when idle. This patch implements the PMR SPR and halts the qemu cpu when there is a change to DME or SME. This means that openrisc qemu in no longer peggs a host cpu at 100%. In order for this to work we need to kick the CPU when timers are expired. Update the cpu timer to kick the cpu upon each timer event.
