* spapr: avoid overhead of finding vhyp class in critical operationsNicholas Piggin2024-05-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | PPC_VIRTUAL_HYPERVISOR_GET_CLASS is used in critical operations like interrupts and TLB misses and is quite costly. Running the kvm-unit-tests sieve program with radix MMU enabled thrashes the TCG TLB and spends a lot of time in TLB and page table walking code. The test takes 67 seconds to complete with a lot of time being spent in code related to finding the vhyp class: 12.01% [.] g_str_hash 8.94% [.] g_hash_table_lookup 8.06% [.] object_class_dynamic_cast 6.21% [.] address_space_ldq 4.94% [.] __strcmp_avx2 4.28% [.] tlb_set_page_full 4.08% [.] address_space_translate_internal 3.17% [.] object_class_dynamic_cast_assert 2.84% [.] ppc_radix64_xlate Keep a pointer to the class and avoid this lookup. This reduces the execution time to 40 seconds. Reviewed-by: Harsh Prateek Bora <harshpb@linux.ibm.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
* hw/ppc/pegasos2: Let pegasos2 machine configure SuperI/O functionsBernhard Beschow2024-02-141-0/+12

* system/cpus: rename qemu_mutex_lock_iothread() to bql_lock()Stefan Hajnoczi2024-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Big QEMU Lock (BQL) has many names and they are confusing. The actual QemuMutex variable is called qemu_global_mutex but it's commonly referred to as the BQL in discussions and some code comments. The locking APIs, however, are called qemu_mutex_lock_iothread() and qemu_mutex_unlock_iothread(). The "iothread" name is historic and comes from when the main thread was split into into KVM vcpu threads and the "iothread" (now called the main loop thread). I have contributed to the confusion myself by introducing a separate --object iothread, a separate concept unrelated to the BQL. The "iothread" name is no longer appropriate for the BQL. Rename the locking APIs to: - void bql_lock(void) - void bql_unlock(void) - bool bql_locked(void) There are more APIs with "iothread" in their names. Subsequent patches will rename them. There are also comments and documentation that will be updated in later patches.

* hw/pci/pci: Remove multifunction parameter from pci_create_simple_multifunction()Bernhard Beschow2023-07-101-1/+1
| | | | | | | | | | | | | | | | | There is also pci_create_simple() which creates non-multifunction PCI devices. Accordingly the parameter is always set to true when a multi function PCI device is to be created. The reason for the parameter's existence seems to be that it is used in the internal PCI code as well which is the only location where it gets set to false. This one usage can be replaced by trivial code. Remove this redundant, error-prone parameter.

* hw/ppc/pegasos2: Fix PCI interrupt routingBALATON Zoltan2023-03-081-1/+25
| | | | | | | | | | | | | | | | | | | | | | According to the PegasosII schematics the PCI interrupt lines are connected to both the gpp pins of the Mv64361 north bridge and the PINT pins of the VT8231 south bridge so guests can get interrupts from either of these. So far we only had the MV64361 connections which worked for on board devices but for additional PCI devices (such as network or sound card added with -device) guest OSes expect interrupt from the ISA IRQ 9 where the firmware routes these PCI interrupts in VT8231 ISA bridge. After the previous patches we can now model this and also remove the board specific connection from mv64361. Also configure routing of these lines when using Virtual Open Firmware to match board firmware for guests that expect this. This fixes PCI interrupts on pegasos2 under Linux, MorphOS and AmigaOS.

* target/ppc: Introduce a vhyp framework for nested HV supportNicholas Piggin2022-02-181-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Introduce virtual hypervisor methods that can support a "Nested KVM HV" implementation using the bare metal 2-level radix MMU, and using HV exceptions to return from H_ENTER_NESTED (rather than cause interrupts). HV exceptions can now be raised in the TCG spapr machine when running a nested KVM HV guest. The main ones are the lev==1 syscall, the hdecr, hdsi and hisi, hv fu, and hv emu, and h_virt external interrupts. HV exceptions are intercepted in the exception handler code and instead of causing interrupts in the guest and switching the machine to HV mode, they go to the vhyp where it may exit the H_ENTER_NESTED hcall with the interrupt vector numer as return value as required by the hcall API. Address translation is provided by the 2-level page table walker that is implemented for the bare metal radix MMU. The partition scope page table is pointed to the L1's partition scope by the get_pate vhc method.

* ppc/pegasos2: Restrict memory to 2 gigabytesBALATON Zoltan2021-10-211-0/+4
| | | | | | | | | | | The CHRP spec this board confirms to only allows 2 GiB of system memory below 4 GiB as the high 2 GiB is allocated to IO and system resources. To avoid problems with memory overlapping these areas restrict RAM to 2 GiB similar to mac_newworld.

* ppc/pegasos2: Fix spurious warning with -biosBALATON Zoltan2021-07-291-1/+1
| | | | | | | | | | | | | The -append option is currently not compatible with -bios (as we don't yet emulate nvram so we can only put it in the environment with VOF). Therefore a warning is printed if -append is used with -bios but because the default value of kernel_cmdline seems to be an empty string instead of NULL this warning was printed even without -append when -bios is used. Only print warning if -append is given.

* ppc/pegasos2: Allow setprop in VOFBALATON Zoltan2021-07-131-0/+10
| | | | | | | | | | Linux needs setprop to fix up the device tree, otherwise it's not finding devices and cannot boot. Since recent VOF change now we need to add a callback to allow this which is what this patch does.

* ppc/pegasos2: Implement some RTAS functions with VOFBALATON Zoltan2021-07-091-0/+137
| | | | | | | | | | | | Linux uses RTAS functions to access PCI devices so we need to provide these with VOF. Implement some of the most important functions to allow booting Linux with VOF. With this the board is now usable without a binary ROM image and we can enable it by default as other boards.

* ppc/pegasos2: Use Virtual Open Firmware as firmware replacementBALATON Zoltan2021-07-091-2/+600
| | | | | | | | | | | | | | | | The pegasos2 board comes with an Open Firmware compliant ROM based on SmartFirmware but it has some changes that are not open source therefore the ROM binary cannot be included in QEMU. Guests running on the board however depend on services provided by the firmware. The Virtual Open Firmware recently added to QEMU implements a minimal set of these services to allow some guests to boot without the original firmware. This patch adds VOF as the default firmware for pegasos2 which allows booting Linux and MorphOS via -kernel option while a ROM image can still be used with -bios for guests that don't run with VOF.

* hw/ppc: Add emulation of Genesi/bPlan Pegasos IIBALATON Zoltan2021-05-041-0/+144
Add new machine called pegasos2 emulating the Genesi/bPlan Pegasos II, a PowerPC board based on the Marvell MV64361 system controller and the VIA VT8231 integrated south bridge/superio chips. It can run Linux, AmigaOS and a wide range of MorphOS versions. Currently a firmware ROM image is needed to boot and only MorphOS has a video driver to produce graphics output. Linux could work too but distros that supported this machine don't include usual video drivers so those only run with serial console for now.
