2022-09-30hw/ide/core.c: Implement ATA INITIALIZE_DEVICE_PARAMETERS commandLev Kujawski
CHS-based disk utilities and operating systems may adjust the logical geometry of a hard drive to cope with the expectations or limitations of software using the ATA INITIALIZE_DEVICE_PARAMETERS command. Prior to this patch, INITIALIZE_DEVICE_PARAMETERS was a nop that always returned success, raising the possibility of data loss or corruption if the CHS<->LBA translation redirected a write to the wrong sector. * hw/ide/core.c ide_reset(): Reset the logical CHS geometry of the hard disk when the power-on defaults feature is enabled. cmd_specify(): a) New function implementing INITIALIZE_DEVICE_PARAMETERS. b) Ignore calls for empty or ATAPI devices. cmd_set_features(): Implement the power-on defaults enable and disable features. struct ide_cmd_table: Switch WIN_SPECIFY from cmd_nop() to cmd_specify(). ide_init_drive(): Set new fields 'drive_heads' and 'drive_sectors' based upon the actual disk geometry. * include/hw/ide/internal.h struct IDEState: a) Store the actual drive CHS values within the new fields 'drive_heads' and 'drive_sectors.' b) Track whether a soft IDE reset should also reset the logical CHS geometry of the hard disk within the new field 'reset_reverts'.

2022-09-30block: add missed block_acct_setup with new block device init procedureDenis V. Lunev
Commit 5f76a7aac156ca75680dad5df4a385fd0b58f6b1 is looking harmless from the first glance, but it has changed things a lot. 'libvirt' uses it to detect that it should follow new initialization way and this changes things considerably. With this procedure followed, blockdev_init() is not called anymore and thus block_acct_setup() helper is not called. This means in particular that defaults for block accounting statistics are changed and account_invalid/account_failed are actually initialized as false instead of true originally. This commit changes things to match original world. There are the following constraints: * new default value in block_acct_init() is set to true * block_acct_setup() inside blockdev_init() is called before blkconf_apply_backend_options() * thus newly created option in block device properties has precedence if specified Signed-off-by: Denis V.

2022-09-27x86: return modified setup_data only if read as memory, not as fileJason A. Donenfeld
If setup_data is being read into a specific memory location, then generally the setup_data address parameter is read first, so that the caller knows where to read it into. In that case, we should return setup_data containing the absolute addresses that are hard coded and determined a priori. This is the case when kernels are loaded by BIOS, for example. In contrast, when setup_data is read as a file, then we shouldn't modify setup_data, since the absolute address will be wrong by definition. This is the case when OVMF loads the image. This allows setup_data to be used like normal, without crashing when EFI tries to use it. (As a small development note, strangely, fw_cfg_add_file_callback() was exported but fw_cfg_add_bytes_callback() wasn't, so this makes that consistent.)

2022-09-27linux-user: Passthrough MADV_DONTNEED for certain file mappingsIlya Leoshkevich
This is a follow-up for commit 892a4f6a750a ("linux-user: Add partial support for MADV_DONTNEED"), which added passthrough for anonymous mappings. File mappings can be handled in a similar manner. In order to do that, mark pages, for which mmap() was passed through, with PAGE_PASSTHROUGH, and then allow madvise() passthrough for these pages. Drop the explicit PAGE_ANON check, since anonymous mappings are expected to have PAGE_PASSTHROUGH anyway. Add PAGE_PASSTHROUGH to PAGE_STICKY in order to keep it on mprotect().

2022-09-27hw/riscv: opentitan: Expose the resetvec as a SoC propertyAlistair Francis
On the OpenTitan hardware the resetvec is fixed at the start of ROM. In QEMU we don't run the ROM code and instead just jump to the next stage. This means we need to be a little more flexible about what the resetvec is. This patch allows us to set the resetvec from the command line with something like this: -global driver=riscv.lowrisc.ibex.soc,property=resetvec,value=0x20000400 This way as the next stage changes we can update the resetvec.

2022-09-26s390x/pci: let intercept devices have separate PCI groupsMatthew Rosato
Let's use the reserved pool of simulated PCI groups to allow intercept devices to have separate groups from interpreted devices as some group values may be different. If we run out of simulated PCI groups, subsequent intercept devices just get the default group. Furthermore, if we encounter any PCI groups from hostdevs that are marked as simulated, let's just assign them to the default group to avoid conflicts between host simulated groups and our own simulated groups.

2022-09-26s390x/pci: enable for load/store interpretationMatthew Rosato
If the ZPCI_OP ioctl reports that is is available and usable, then the underlying KVM host will enable load/store intepretation for any guest device without a SHM bit in the guest function handle. For a device that will be using interpretation support, ensure the guest function handle matches the host function handle; this value is re-checked every time the guest issues a SET PCI FN to enable the guest device as it is the only opportunity to reflect function handle changes. By default, unless interpret=off is specified, interpretation support will always be assumed and exploited if the necessary ioctl and features are available on the host kernel. When these are unavailable, we will silently revert to the interception model; this allows existing guest configurations to work unmodified on hosts with and without zPCI interpretation support, allowing QEMU to choose the best support model available.

This work is based on: https://patchew.org/QEMU/20220317125534.38706-1-philippe.mathieu.daude@gmail.com/ Simplify the initialization dance by running qemu_init() in the main thread before the Cocoa event loop starts. The secondary thread only runs only qemu_main_loop() and qemu_cleanup(). This fixes a case where addRemovableDevicesMenuItems() calls qmp_query_block() while expecting the main thread to still hold the BQL. Overriding the code after calling qemu_init() is done by dynamically replacing a function pointer variable, qemu_main when initializing ui/cocoa, which unifies the static implementation of main() for builds with ui/cocoa and ones without ui/cocoa.

2022-09-14target/arm: Make boards pass base address to armv7m_load_kernel()Peter Maydell
Currently armv7m_load_kernel() takes the size of the block of memory where it should load the initial guest image, but assumes that it should always load it at address 0. This happens to be true of all our M-profile boards at the moment, but it isn't guaranteed to always be so: M-profile CPUs can be configured (via init-svtor and init-nsvtor, which match equivalent hardware configuration signals) to have the initial vector table at any address, not just zero. (For instance the Teeny board has the boot ROM at address 0x0200_0000.) Add a base address argument to armv7m_load_kernel(), so that callers now pass in both base address and size. All the current callers pass 0, so this is not a behaviour change.

2022-09-13semihosting: Allow optional use of semihosting from userspacePeter Maydell
Currently our semihosting implementations generally prohibit use of semihosting calls in system emulation from the guest userspace. This is a very long standing behaviour justified originally "to provide some semblance of security" (since code with access to the semihosting ABI can do things like read and write arbitrary files on the host system). However, it is sometimes useful to be able to run trusted guest code which performs semihosting calls from guest userspace, notably for test code. Add a command line suboption to the existing semihosting-config option group so that you can explicitly opt in to semihosting from guest userspace with -semihosting-config userspace=on (There is no equivalent option for the user-mode emulator, because there by definition all code runs in userspace and has access to semihosting already.) This commit adds the infrastructure for the command line option and adds a bool 'is_user' parameter to the function semihosting_userspace_enabled() that target code can use to check whether it should be permitting the semihosting call for userspace. It mechanically makes all the callsites pass 'false', so they continue checking "is semihosting enabled in general". Subsequent commits will make each target that implements semihosting honour the userspace=on option by passing the correct value and removing whatever "don't do this for userspace" checking they were doing by hand.

2022-09-07hw/riscv: microchip_pfsoc: fix kernel panics due to missing peripheralsConor Dooley
Booting using "Direct Kernel Boot" for PolarFire SoC & skipping u-boot entirely is probably not advisable, but it does at least show signs of life. Recent Linux kernel versions make use of peripherals that are missing definitions in QEMU and lead to kernel panics. These issues almost certain rear their head for other methods of booting, but I was unable to figure out a suitable HSS version that is recent enough to support these peripherals & works with QEMU. With these peripherals added, booting a kernel with the following hangs hangs waiting for the system controller's hwrng, but the kernel no longer panics. With the Linux driver for hwrng disabled, it boots to console. qemu-system-riscv64 -M microchip-icicle-kit \ -m 2G -smp 5 \ -kernel $(vmlinux_bin) \ -dtb $(dtb)\ -initrd $(initramfs) \ -display none -serial null \ -serial stdio More peripherals are added than strictly required to fix the panics in the hopes of avoiding a replication of this problem in the future. Some of the peripherals which are in the device tree for recent kernels are implemented in the FPGA fabric. The eMMC/SD mux, which exists as an unimplemented device is replaced by a wider entry. This updated entry covers both the mux & the remainder of the FPGA fabric connected to the MSS using Fabric Interrconnect (FIC) 3.
