2021-07-02hw/gpio/gpio_pwr: use shutdown function for rebootMaxim Uvarov1-1/+1
qemu has 2 type of functions: shutdown and reboot. Shutdown function has to be used for machine shutdown. Otherwise we cause a reset with a bogus "cause" value, when we intended a shutdown.

This is just enough to make reboot and poweroff work. Works for linux, u-boot, and the arm trusted firmware. Not tested, but should work for plan9, and bare-metal/hobby OSes, since they seem to generally do what linux does for reset. The watchdog timer functionality is not yet implemented.

2021-06-29hw/nvme: fix pin-based interrupt behavior (again)Klaus Jensen2-1/+18
Jakub noticed[1] that, when using pin-based interrupts, the device will unconditionally deasssert when any CQEs are acknowledged. However, the pin should not be deasserted if other completion queues still holds unacknowledged CQEs. The bug is an artifact of commit ca247d35098d ("hw/block/nvme: fix pin-based interrupt behavior") which fixed one bug but introduced another. This is the third time someone tries to fix pin-based interrupts (see commit 5e9aa92eb1a5 ("hw/block: Fix pin-based interrupt behaviour of NVMe"))... Third time's the charm, so fix it, again, by keeping track of how many CQs have unacknowledged CQEs and only deassert when all are cleared.

2021-06-29Partially revert "hw/block/nvme: drain namespaces on sq deletion"Klaus Jensen1-17/+2
This partially reverts commit 98f84f5a4eca5c03e32fff20f246d9b4b96d6422. Since all "multi aio" commands are now reimplemented to properly track the nested aiocbs, we can revert the "hack" that was introduced to make sure all requests we're properly drained upon sq deletion. The revert is partial since we keep the assert that no outstanding requests remain on the submission queue after the explicit cancellation.

In the Zoned Namespace Command Set Specification, chapter 2.5.1 Managing resources "The controller may transition zones in the ZSIO:Implicitly Opened state to the ZSC:Closed state for resource management purposes." The word may in this sentence means that automatically transitioning an implicitly opened zone to closed is completely optional. Add a new parameter so that the user can control if this automatic transitioning should be performed or not. Being able to control this can help with verifying that e.g. a user-space program behaves properly even without this optional ZNS feature. The default value is set to true, in order to not change the existing behavior.

Some machines use floppy controllers via the SysBus interface, and don't need to pull in all the SysBus code. Extract the SysBus specific code to a new unit: fdc-sysbus.c, and add a new Kconfig symbol: "FDC_SYSBUS".

Some machines use floppy controllers via the SysBus interface, and don't need to pull in all the ISA code. Extract the ISA specific code to a new unit: fdc-isa.c, and add a new Kconfig symbol: "FDC_ISA". This allows us to remove the FIXME from commit dd0ff8191ab ("isa: express SuperIO dependencies with Kconfig").

2021-06-25block: add max_hw_transfer to BlockLimitsPaolo Bonzini1-1/+1
For block host devices, I/O can happen through either the kernel file descriptor I/O system calls (preadv/pwritev, io_submit, io_uring) or the SCSI passthrough ioctl SG_IO. In the latter case, the size of each transfer can be limited by the HBA, while for file descriptor I/O the kernel is able to split and merge I/O in smaller pieces as needed. Applying the HBA limits to file descriptor I/O results in more system calls and suboptimal performance, so this patch splits the max_transfer limit in two: max_transfer remains valid and is used in general, while max_hw_transfer is limited to the maximum hardware size. max_hw_transfer can then be included by the scsi-generic driver in the block limits page, to ensure that the stricter hardware limit is used.

2021-06-25scsi-generic: pass max_segments via max_iov field in BlockLimitsPaolo Bonzini1-2/+4
I/O to a disk via read/write is not limited by the number of segments allowed by the host adapter; the kernel can split requests if needed, and the limit imposed by the host adapter can be very low (256k or so) to avoid that SG_IO returns EINVAL if memory is heavily fragmented. Since this value is only interesting for SG_IO-based I/O, do not include it in the max_transfer and only take it into account when patching the block limits VPD page in the scsi-generic device.
