* | ide: Increment BB in-flight counter for TRIM BHHanna Reitz2022-03-071-0/+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.

* ide: Cap LBA28 capacity announcement to 2^28-1Samuel Thibault2021-11-021-2/+6
| | | | | | | | | | | | | | The LBA28 capacity (at offsets 60/61 of identification) is supposed to express the maximum size supported by LBA28 commands. If the device is larger than this, we have to cap it to 2^28-1. At least NetBSD happens to be using this value to determine whether to use LBA28 or LBA48 for its commands, using LBA28 for sectors that don't need LBA48. This commit thus fixes NetBSD access to disks larger than 128GiB.

* block: Separate blk_is_writable() and blk_supports_write_perm()Kevin Wolf2021-01-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, blk_is_read_only() tells whether a given BlockBackend can only be used in read-only mode because its root node is read-only. Some callers actually try to answer a slightly different question: Is the BlockBackend configured to be writable, by taking write permissions on the root node? This can differ, for example, for CD-ROM devices which don't take write permissions, but may be backed by a writable image file. scsi-cd allows write requests to the drive if blk_is_read_only() returns false. However, the write request will immediately run into an assertion failure because the write permission is missing. This patch introduces separate functions for both questions. blk_supports_write_perm() answers the question whether the block node/image file can support writable devices, whereas blk_is_writable() tells whether the BlockBackend is currently configured to be writable. All calls of blk_is_read_only() are converted to one of the two new functions.

* ide: model HOB correctlyJohn Snow2020-10-011-8/+7Star
| | | | | | | | | | | | | | | | | | | | | I have been staring at this FIXME for years and I never knew what it meant. I finally stumbled across it! When writing to the command registers, the old value is shifted into a HOB copy of the register and the new value is written into the primary register. When reading registers, the value retrieved is dependent on the HOB bit in the CONTROL register. By setting bit 7 (0x80) in CONTROL, any register read will, if it has one, yield the HOB value for that register instead. Our code has a problem: We were using bit 7 of the DEVICE register to model this. We use bus->cmd roughly as the control register already, as it stores the value from ide_ctrl_write. Lastly, all command register writes reset the HOB, so fix that, too. Signed-off-by: John Snow <jsnow@redhat.com>
* ide: don't tamper with the device registerJohn Snow2020-10-011-2/+2
| | | | | | | | | | | | | | | In real ISA operation, register writes go out to an entire bus channel and all listening devices receive the write. The devices do not toggle the DEV bit based on their own configuration, nor does the HBA intermediate or tamper with that value. The reality of the matter is that DEV0/DEV1 accordingly will react to command register writes based on whether or not the device was selected. This does not fix a known bug, but it makes the code slightly simpler and more obvious. Signed-off-by: John Snow <jsnow@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | The commit a718978ed58a from July 2015 introduced the assertion which implies that the size of successful DMA transfers handled in ide_dma_cb() should be multiple of 512 (the size of a sector). But guest systems can initiate DMA transfers that don't fit this requirement. For fixing that let's check the number of bytes prepared for the transfer by the prepare_buf() handler. The code in ide_dma_cb() must behave according to the Programming Interface for Bus Master IDE Controller (Revision 1.0 5/16/94): 1. If PRDs specified a smaller size than the IDE transfer size, then the Interrupt and Active bits in the Controller status register are not set (Error Condition). 2. If the size of the physical memory regions was equal to the IDE device transfer size, the Interrupt bit in the Controller status register is set to 1, Active bit is set to 0. 3. If PRDs specified a larger size than the IDE transfer size, the Interrupt and Active bits in the Controller status register are both set to 1.

* ide: support reporting of rotation rateDaniel P. Berrange2017-10-121-0/+1
| | | | | | | | | | | | | | | | | | | | | The Linux kernel will query the ATA IDENTITY DEVICE data, word 217 to determine the rotations per minute of the disk. If this has the value 1, it is taken to be an SSD and so Linux sets the 'rotational' flag to 0 for the I/O queue and will stop using that disk as a source of random entropy. Other operating systems may also take into account rotation rate when setting up default behaviour. Mgmt apps should be able to set the rotation rate for virtualized block devices, based on characteristics of the host storage in use, so that the guest OS gets sensible behaviour out of the box. This patch thus adds a 'rotation-rate' parameter for 'ide-hd' device types. Signed-off-by: Daniel P.
