Trying to recalculate it here with another rules leads to errors, such as: 1. 003f230e37d7 ("machine: Tweak the order of topology members in struct CpuTopology") changes the meaning of smp.cores but doesn't fix original smp.cores uses. With the introduction of cluster, now smp.cores means the number of cores in one cluster. So smp.cores * smp.threads just means the threads in a cluster not in a socket. 2. On the other hand, we shouldn't use smp.cpus here because it indicates the initial number of online CPUs at the boot time, and is not mathematically related to smp.sockets. So stop reinventing the another wheel and use the topo values that has been calculated.

In the below example, it is expected to dump two blocks. (qemu) info mtree -f ... ... 00000000090a0000-00000000090a0fff (prio 0, ram): pvtime KVM ... ... 0000000040000000-00000001bfffffff (prio 0, ram): mach-virt.ram KVM ... ... However, there is an issue with get_next_page() so that the pages for "mach-virt.ram" will not be dumped. At line 1296, although we have reached at the end of the 'pvtime' block, since it is not aligned to the page_size (e.g., 0x10000), it will not break at line 1298. 1255 static bool get_next_page(GuestPhysBlock **blockptr, uint64_t *pfnptr, 1256 uint8_t **bufptr, DumpState *s) ... ... 1294 memcpy(buf + addr % page_size, hbuf, n); 1295 addr +=3D n; 1296 if (addr % page_size =3D=3D 0) { 1297 /* we filled up the page */ 1298 break; 1299 } As a result, get_next_page() will continue to the next block ("mach-virt.ram"). Finally, when get_next_page() returns to the caller: - 'pfnptr' is referring to the 'pvtime' - but 'blockptr' is referring to the "mach-virt.ram" When get_next_page() is called the next time, "*pfnptr +=3D 1" still refers to the prior 'pvtime'. It will exit immediately because it is out of the range of the current "mach-virt.ram". The fix is to break when it is time to come to the next block, so that both 'pfnptr' and 'blockptr' refer to the same block.

When running QEMU with "-d guest_errors", it shows an error message like this: virtio_gpu_create_mapping_iov: nr_entries is too big (83886080 > 16384) which indicates that this value has not been properly byte-swapped. And indeed, the virtio_gpu_create_blob_bswap() function (that should swap the fields in the related structure) fails to swap some of the entries.

This actually confused libvirt, which uses "none" machine model to probe the KVM availability, on M2 MacBook Air. Fix this by using Host_IPA_Limit as the default type when KVM_CAP_ARM_VM_IPA_SIZE is available.

Sending the unsupported command again, will correctly have ERR_STAT set. When ide_cmd_permitted() returns false, it calls ide_abort_command(). ide_abort_command() first calls ide_transfer_stop(), which will call ide_transfer_halt() and ide_cmd_done(), after that ide_abort_command() sets ERR_STAT in status. ide_cmd_done() for AHCI will call ahci_write_fis_d2h() which writes the current status in the FIS, and raises an IRQ. (The status here will not have ERR_STAT set!). Thus, we cannot call ide_transfer_stop() before setting ERR_STAT, as ide_transfer_stop() will result in the FIS being written and an IRQ being raised. The reason why it works the second time, is that ERR_STAT will still be set from the previous command, so when writing the FIS, the completion will correctly have ERR_STAT set. Set ERR_STAT before writing the FIS (calling cmd_done), so that we will raise an error IRQ correctly when receiving an unsupported command.

PxCI is currently cleared by handle_cmd(), but we don't write the D2H FIS to the FIS Receive Area that actually caused PxCI to be cleared. Similar to how ahci_pio_transfer() calls ahci_write_fis_pio() with an additional parameter to write a PIO Setup FIS without raising an IRQ, add a parameter to ahci_write_fis_d2h() so that ahci_write_fis_d2h() also can write the FIS to the FIS Receive Area without raising an IRQ. Change process_ncq_command() to call ahci_write_fis_d2h() without raising an IRQ (similar to ahci_pio_transfer()), such that the FIS Receive Area is in sync with the PxTFD shadow register. E.g. Linux reads status and error fields from the FIS Receive Area directly, so it is wise to keep the FIS Receive Area and the PxTFD shadow register in sync.

For non-NCQ, PxCI is cleared on command completed successfully. (A non-NCQ command that completes with error does not clear PxCI.) The current QEMU implementation either clears PxCI in check_cmd(), or in ahci_cmd_done(). check_cmd() will clear PxCI for a command if handle_cmd() returns 0. handle_cmd() will return -1 if BUSY or DRQ is set. The QEMU implementation for NCQ commands will currently not set BUSY or DRQ, so they will always have PxCI cleared by handle_cmd(). ahci_cmd_done() will never even get called for NCQ commands. Non-NCQ commands are executed by ide_bus_exec_cmd(). Non-NCQ commands in QEMU are implemented either in a sync or in an async way. For non-NCQ commands implemented in a sync way, the command handler will return true, and when ide_bus_exec_cmd() sees that a command handler returns true, it will call ide_cmd_done() (which will call ahci_cmd_done()). For a command implemented in a sync way, ahci_cmd_done() will do nothing (since busy_slot is not set). Instead, after ide_bus_exec_cmd() has finished, check_cmd() will clear PxCI for these commands. For non-NCQ commands implemented in an async way (using either aiocb or pio_aiocb), the command handler will return false, ide_bus_exec_cmd() will not call ide_cmd_done(), instead it is expected that the async callback function will call ide_cmd_done() once the async command is done. handle_cmd() will set busy_slot, if and only if BUSY or DRQ is set, and this is checked _after_ ide_bus_exec_cmd() has returned. handle_cmd() will return -1, so check_cmd() will not clear PxCI. When the async callback calls ide_cmd_done() (which will call ahci_cmd_done()), it will see that busy_slot is set, and ahci_cmd_done() will clear PxCI. This seems racy, since busy_slot is set _after_ ide_bus_exec_cmd() has returned. The callback might come before busy_slot gets set. And it is quite confusing that ahci_cmd_done() will be called for all non-NCQ commands when the command is done, but will only clear PxCI in certain cases, even though it will always write a D2H FIS and raise an IRQ. Even worse, in the case where ahci_cmd_done() does not clear PxCI, it still raises an IRQ. Host software might thus read an old PxCI value, since PxCI is cleared (by check_cmd()) after the IRQ has been raised. Try to simplify this by always setting busy_slot for non-NCQ commands, such that ahci_cmd_done() will always be responsible for clearing PxCI for non-NCQ commands. For NCQ commands, clear PxCI when we receive the D2H FIS, but before raising the IRQ, see AHCI 1.3.1, section 5.3.8, states RegFIS:Entry and RegFIS:ClearCI.

This field is not cleared by a COMRESET or a software reset. According to AHCI 1.3.1 definition of PxCI: This field is also cleared when PxCMD.ST is written from a '1' to a '0' by software. Clearing PxCMD.ST is part of the error recovery procedure, see AHCI 1.3.1, section "6.2 Error Recovery". If we don't clear PxCI on error recovery, the previous command will incorrectly still be marked as pending after error recovery.

If ERR_STAT is set, we jump to state ERR:FatalTaskfile, which will raise a TFES IRQ unconditionally, regardless if the I bit is set in the FIS or not. Thus, we should never raise a normal IRQ after having sent an error IRQ. It is valid to signal successfully completed commands as finished in the same SDB FIS that generates the error IRQ. The important thing is that commands that did not complete successfully (e.g. commands that were aborted, do not get the finished bit set). Before this commit, there was never a TFES IRQ raised on NCQ error.

This is completely wrong. The SError register has a clear definition, where each bit represents a different error, see PxSERR definition in AHCI 1.3.1. If we write a random value (like the NCQ tag) in SError, e.g. Linux will read SError, and will trigger arbitrary error handling depending on the NCQ tag that happened to be executing. In case of success, ncq_cb() will call ncq_finish(). In case of error, ncq_cb() will call ncq_err() (which will clear ncq_tfs->used), and then call ncq_finish(), thus using ncq_tfs->used is sufficient to tell if finished should get set or not.
