2023-07-07ppc/pnv: Add P10 quad xscom modelJoel Stanley
Add a PnvQuad class for the P10 powernv machine. No xscoms are implemented yet, but this allows them to be added. The size is reduced to avoid the quad region from overlapping with the core region. address-space: xscom-0 0000000000000000-00000003ffffffff (prio 0, i/o): xscom-0 0000000100000000-00000001000fffff (prio 0, i/o): xscom-quad.0 0000000100108000-0000000100907fff (prio 0, i/o): xscom-core.3 0000000100110000-000000010090ffff (prio 0, i/o): xscom-core.2 0000000100120000-000000010091ffff (prio 0, i/o): xscom-core.1 0000000100140000-000000010093ffff (prio 0, i/o): xscom-core.0 Signed-off-by: Joel Stanley <joel@jms.id.au> Reviewed-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: Frederic Barrat <fbarrat@linux.ibm.com> Message-ID: <20230704054204.168547-4-joel@jms.id.au> Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com>

2023-07-03plugins: force slow path when plugins instrument memory opsAlex Bennée
The lack of SVE memory instrumentation has been an omission in plugin handling since it was introduced. Fortunately we can utilise the probe_* functions to force all all memory access to follow the slow path. We do this by checking the access type and presence of plugin memory callbacks and if set return the TLB_MMIO flag. We have to jump through a few hoops in user mode to re-use the flag but it was the desired effect: ./qemu-system-aarch64 -display none -serial mon:stdio \ -M virt -cpu max -semihosting-config enable=on \ -kernel ./tests/tcg/aarch64-softmmu/memory-sve \ -plugin ./contrib/plugins/libexeclog.so,ifilter=st1w,afilter=0x40001808 -d plugin gives (disas doesn't currently understand st1w): 0, 0x40001808, 0xe54342a0, ".byte 0xa0, 0x42, 0x43, 0xe5", store, 0x40213010, RAM, store, 0x40213014, RAM, store, 0x40213018, RAM And for user-mode: ./qemu-aarch64 \ -plugin contrib/plugins/libexeclog.so,afilter=0x4007c0 \ -d plugin \ ./tests/tcg/aarch64-linux-user/sha512-sve gives: 1..10 ok 1 - do_test(&tests[i]) 0, 0x4007c0, 0xa4004b80, ".byte 0x80, 0x4b, 0x00, 0xa4", load, 0x5500800370, load, 0x5500800371, load, 0x5500800372, load, 0x5500800373, load, 0x5500800374, load, 0x5500800375, load, 0x5500800376, load, 0x5500800377, load, 0x5500800378, load, 0x5500800379, load, 0x550080037a, load, 0x550080037b, load, 0x550080037c, load, 0x550080037d, load, 0x550080037e, load, 0x550080037f, load, 0x5500800380, load, 0x5500800381, load, 0x5500800382, load, 0x5500800383, load, 0x5500800384, load, 0x5500800385, load, 0x5500800386, lo ad, 0x5500800387, load, 0x5500800388, load, 0x5500800389, load, 0x550080038a, load, 0x550080038b, load, 0x550080038c, load, 0x550080038d, load, 0x550080038e, load, 0x550080038f, load, 0x5500800390, load, 0x5500800391, load, 0x5500800392, load, 0x5500800393, load, 0x5500800394, load, 0x5500800395, load, 0x5500800396, load, 0x5500800397, load, 0x5500800398, load, 0x5500800399, load, 0x550080039a, load, 0x550080039b, load, 0x550080039c, load, 0x550080039d, load, 0x550080039e, load, 0x550080039f, load, 0x55008003a0, load, 0x55008003a1, load, 0x55008003a2, load, 0x55008003a3, load, 0x55008003a4, load, 0x55008003a5, load, 0x55008003a6, load, 0x55008003a7, load, 0x55008003a8, load, 0x55008003a9, load, 0x55008003aa, load, 0x55008003ab, load, 0x55008003ac, load, 0x55008003ad, load, 0x55008003ae, load, 0x55008003af (4007c0 is the ld1b in the sha512-sve) Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Cc: Robert Henry <robhenry@microsoft.com> Cc: Aaron Lindsay <aaron@os.amperecomputing.com> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20230630180423.558337-20-alex.bennee@linaro.org>

2023-06-30vfio/migration: Make VFIO migration non-experimentalAvihai Horon
The major parts of VFIO migration are supported today in QEMU. This includes basic VFIO migration, device dirty page tracking and precopy support. Thus, at this point in time, it seems appropriate to make VFIO migration non-experimental: remove the x prefix from enable_migration property, change it to ON_OFF_AUTO and let the default value be AUTO. In addition, make the following adjustments: 1. When enable_migration is ON and migration is not supported, fail VFIO device realization. 2. When enable_migration is AUTO (i.e., not explicitly enabled), require device dirty tracking support. This is because device dirty tracking is currently the only method to do dirty page tracking, which is essential for migrating in a reasonable downtime. Setting enable_migration to ON will not require device dirty tracking. 3. Make migration error and blocker messages more elaborate. 4. Remove error prints in vfio_migration_query_flags(). 5. Rename trace_vfio_migration_probe() to trace_vfio_migration_realize().

2023-06-30vfio/migration: Reset bytes_transferred properlyAvihai Horon
Currently, VFIO bytes_transferred is not reset properly: 1. bytes_transferred is not reset after a VM snapshot (so a migration following a snapshot will report incorrect value). 2. bytes_transferred is a single counter for all VFIO devices, however upon migration failure it is reset multiple times, by each VFIO device. Fix it by introducing a new function vfio_reset_bytes_transferred() and calling it during migration and snapshot start. Remove existing bytes_transferred reset in VFIO migration state notifier, which is not needed anymore.

2023-06-30vfio/migration: Add support for switchover ack capabilityAvihai Horon
Loading of a VFIO device's data can take a substantial amount of time as the device may need to allocate resources, prepare internal data structures, etc. This can increase migration downtime, especially for VFIO devices with a lot of resources. To solve this, VFIO migration uAPI defines "initial bytes" as part of its precopy data stream. Initial bytes can be used in various ways to improve VFIO migration performance. For example, it can be used to transfer device metadata to pre-allocate resources in the destination. However, for this to work we need to make sure that all initial bytes are sent and loaded in the destination before the source VM is stopped. Use migration switchover ack capability to make sure a VFIO device's initial bytes are sent and loaded in the destination before the source stops the VM and attempts to complete the migration. This can significantly reduce migration downtime for some devices.

2023-06-30vfio/migration: Add VFIO migration pre-copy supportAvihai Horon
Pre-copy support allows the VFIO device data to be transferred while the VM is running. This helps to accommodate VFIO devices that have a large amount of data that needs to be transferred, and it can reduce migration downtime. Pre-copy support is optional in VFIO migration protocol v2. Implement pre-copy of VFIO migration protocol v2 and use it for devices that support it. Full description of it can be found in the following Linux commit: 4db52602a607 ("vfio: Extend the device migration protocol with PRE_COPY").

VFIO migration flags are queried once in vfio_migration_init(). Store them in VFIOMigration so they can be used later to check the device's migration capabilities without re-querying them. This will be used in the next patch to check if the device supports precopy migration.

2023-06-30migration: Implement switchover ack logicAvihai Horon
Implement switchover ack logic. This prevents the source from stopping the VM and completing the migration until an ACK is received from the destination that it's OK to do so. To achieve this, a new SaveVMHandlers handler switchover_ack_needed() and a new return path message MIG_RP_MSG_SWITCHOVER_ACK are added. The switchover_ack_needed() handler is called during migration setup in the destination to check if switchover ack is used by the migrated device. When switchover is approved by all migrated devices in the destination that support this capability, the MIG_RP_MSG_SWITCHOVER_ACK return path message is sent to the source to notify it that it's OK to do switchover.

2023-06-28escc: emulate dip switch language layout settings on SUN keyboardHenrik Carlqvist
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout of the keyboard. Solaris makes an ioctl to query the value of the dipswitches and uses that value to select keyboard layout. Also the SUN bios like the one in the file ss5.bin uses this value to support at least some keyboard layouts. However, the OpenBIOS provided with qemu is hardcoded to always use an US keyboard layout. Before this patch, qemu allways gave dip switch value 0x21 (US keyboard), this patch uses a command line switch like "-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is used to lookup values from arguments like: -global escc.chnA-sunkbd-layout=fr -global escc.chnA-sunkbd-layout=es But the patch also accepts numeric dip switch values directly: -global escc.chnA-sunkbd-layout=0x2b -global escc.chnA-sunkbd-layout=43 Both values above are the same and select swedish keyboard as explained in table 3-15 at https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html Unless you want to do a full Solaris installation but happen to have access to a Sun bios file, the easiest way to test that the patch works is to: qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin If you already happen to have a Solaris installation in a qemu disk image file you can easily try different keyboard layouts after this patch is applied.

If the caller keeps the AioContext lock for a block node in an iothread, polling in bdrv_graph_wrlock() deadlocks if the condition isn't fulfilled immediately. Now that all callers make sure to actually have the AioContext locked when they call bdrv_replace_child_noperm() like they should, we can change bdrv_graph_wrlock() to take a BlockDriverState whose AioContext lock the caller holds (NULL if it doesn't) and unlock it temporarily while polling.

To support restoring offloads state in vdpa, it is necessary to expose the function virtio_net_supported_guest_offloads(). According to VirtIO standard, "Upon feature negotiation corresponding offload gets enabled to preserve backward compatibility.". Therefore, QEMU uses this function to get the device supported offloads. This allows QEMU to know the device's defaults and skip the control message sending if these defaults align with the driver's configuration. Note that the device's defaults can mismatch the driver's configuration only at live migration.
