2022-10-20hw/ide/microdrive: Use device_cold_reset() for self-resetsPeter Maydell1-4/+4
Currently the microdrive code uses device_legacy_reset() to reset itself, and has its reset method call reset on the IDE bus as the last thing it does. Switch to using device_cold_reset(). The only concrete microdrive device is the TYPE_DSCM1XXXX; it is not command-line pluggable, so it is used only by the old pxa2xx Arm boards 'akita', 'borzoi', 'spitz', 'terrier' and 'tosa'. You might think that this would result in the IDE bus being reset automatically, but it does not, because the IDEBus type does not set the BusClass::reset method. Instead the controller must explicitly call ide_bus_reset(). We therefore leave that call in md_reset(). Note also that because the PCMCIA card device is a direct subclass of TYPE_DEVICE and we don't model the PCMCIA controller-to-card interface as a qbus, PCMCIA cards are not on any qbus and so they don't get reset when the system is reset. The reset only happens via the dscm1xxxx_attach() and dscm1xxxx_detach() functions during machine creation. Because our aim here is merely to try to get rid of calls to the device_legacy_reset() function, we leave these other dubious reset-related issues alone. (They all stem from this code being absolutely ancient.)

2022-09-30hw/ide/core.c: Implement ATA INITIALIZE_DEVICE_PARAMETERS commandLev Kujawski1-3/+26
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'.

Prior to this patch, cmd_exec_dev_diagnostic relied upon ide_set_signature to clear the device register. While the preservation of the drive bit by ide_set_signature is necessary for the DEVICE RESET, IDENTIFY DEVICE, and READ SECTOR commands, ATA/ATAPI-6 specifies that "DEV shall be cleared to zero" for EXECUTE DEVICE DIAGNOSTIC.

2022-05-25ide_ioport_read: Return lower octet of data register instead of 0xFFLev Kujawski2-2/+8
Prior to this patch, the pre-GRUB Solaris x86 bootloader would fail to load on QEMU with the following screen output: SunOS Secondary Boot version 3.00 prom_panic: Could not mount filesystem. Entering boot debugger: [136419]: _ This occurs because the bootloader issues an ATA IDENTIFY DEVICE command, and then reads the resulting 256 words of parameter information using inb rather than the correct inw. As the previous behavior of QEMU was to return 0xFF and not advance the drive's sector buffer, DRQ would never be cleared and the bootloader would be blocked from selecting a secondary ATA device, such as an optical drive.

2022-03-07ide: Increment BB in-flight counter for TRIM BHHanna Reitz1-0/+7
When we still have an AIOCB registered for DMA operations, we try to settle the respective operation by draining the BlockBackend associated with the IDE device. However, this assumes that every DMA operation is associated with an increment of the BlockBackend’s in-flight counter (e.g. through some ongoing I/O operation), so that draining the BB until its in-flight counter reaches 0 will settle all DMA operations. That is not the case: For TRIM, the guest can issue a zero-length operation that will not result in any I/O operation forwarded to the BlockBackend, and also not increment the in-flight counter in any other way. In such a case, blk_drain() will be a no-op if no other operations are in flight. It is clear that if blk_drain() is a no-op, the value of s->bus->dma->aiocb will not change between checking it in the `if` condition and asserting that it is NULL after blk_drain(). The particular problem is that ide_issue_trim() creates a BH (ide_trim_bh_cb()) to settle the TRIM request: iocb->common.cb() is ide_dma_cb(), which will either create a new request, or find the transfer to be done and call ide_set_inactive(), which clears s->bus->dma->aiocb. Therefore, the blk_drain() must wait for ide_trim_bh_cb() to run, which currently it will not always do. To fix this issue, we increment the BlockBackend's in-flight counter when the TRIM operation begins (in ide_issue_trim(), when the ide_trim_bh_cb() BH is created) and decrement it when ide_trim_bh_cb() is done.

2022-01-18hw/dma: Let dma_buf_read() / dma_buf_write() propagate MemTxResultPhilippe Mathieu-Daudé1-4/+4
Since commit 292e13142d2, dma_buf_rw() returns a MemTxResult type. Do not discard it, return it to the caller. Pass the previously returned value (the QEMUSGList residual size, which was rarely used) as an optional argument. With this new API, SCSIRequest::residual might now be accessed via a pointer. Since the size_t type does not have the same size on 32 and 64-bit host architectures, convert it to a uint64_t, which is big enough to hold the residual size, and the type is constant on both 32/64-bit hosts. Update the few dma_buf_read() / dma_buf_write() callers to the new API.
