This patch fixes two issues with persistent grants and the disk PV backend
(Qdisk):
- Keep track of memory regions where persistent grants have been mapped
since we need to unmap them as a whole. It is not possible to unmap a
single grant if it has been batch-mapped. A new check has also been added
to make sure persistent grants are only used if the whole mapped region
can be persistently mapped in the batch_maps case.
- Unmap persistent grants before switching to the closed state, so the
frontend can also free them.

In order to make handle_cmd more readable at the macro level,
the details of how to decompose particular types of FIS packets
are left to helper functions.
In our case, the only type of FIS packet we currently expect to
see is a Register H2D FIS packet, but the gory details of its
decomposition are of no particular interest in handle_cmd.
This patch keeps the receipt of FIS packets and the decomposition
thereof separated to two different functions.

This patch introduces a few changes to how FIS packets are
deciphered in the AHCI virtual device. The summary of
changes can be grouped into two pieces:
[A] Changes to how we apply a preliminary sieve to FISes,
[B] Changes in how we internalize a decomposed FIS.
== Changes to how we apply a preliminary sieve to FISes ==
(1) Packets may now either update the Control register or
the Command register, but not both. This is according
to the SATA 3.2 specification which states:
"...the device either initiates processing of the command
indicated in the Command register or initiates processing
of the control request indicated [...] depending on the
state of the C bit in the FIS."
See SATA 3.2 section 10.5.5.4, "Reception" in the 10.5.5
"Register Host to Device FIS" section.
This change accounts for the first two regions of change
within the diff. All other changes belong to the following
changes.
== Changes in how we internalize a decomposed FIS ==
(2) Instead of trying to extract the sector number out of the
FIS from bytes 4-10 and setting it with ide_set_sector,
we set the appropriate IDEState registers and trust that
ide_get_sector can retrieve the correct sector later.
By "constructing" the sector for use with ide_set_sector,
we are duplicating the mechanisms of ide_get_sector.
This change makes the FIS decomposition more obvious.
SATA 3.2 as a specification does not make the legacy
register mapping with respect to the D2H FIS obvious.
However, SATA 3.2 section 10.5.5.1 "Register Host to
Device FIS layout" describes all of the "cmd_fis"
bytes:
0 - FIS Type (0x27)
1 - Port Multiplier Port and Command Update flag
2 - ATA Command
3 - Features_Low
4 - LBA 7:0
5 - LBA 15:8
6 - LBA 23:16
7 - Device, AKA "Drive Select."
8 - LBA 31:24
9 - LBA 39:32
10 - LBA 47:40
11 - Features_High
12 - Count Low
13 - Count High
14 - ICC
15 - Control
16-19 - Auxiliary (for NCQ, defined per-command)
Most of these registers map to existing IDEState registers
in obvious ways, especially features, select, hob_features,
and nsector (count). ICC is reserved in older specifications
but is not supported in our implementation, and remains
unused here. The Control register is not valid for a command
that is trying to update the command register and is to be
considered reserved at this point.
What is not obvious is the LBA register mappings, but SATA 1.0
can help inform of us legacy device support, see SATA 1.0 section
8.5.2 "Register - Host to Device."
LBA 7:0 - Sector Number (sector)
LBA 15:8 - Cyl Low (lcyl)
LBA 23:16 - Cyl High (hcyl)
LBA 31:24 - Sector Num Exp. (hob_sector)
LBA 39:32 - Cyl Low Exp. (hob_lcyl)
LBA 47:40 - Cyl High Exp. (hob_hcyl)
These mappings help guide which registers the FIS should be decomposed
into/towards for CHS, LBA28 and LBA48 commands.
As a note: The prior confusion that can be seen in the documentation
arises from the fact that CHS and LBA28 commands use the low nybble
of the drive select register to store LBA 27:24, whereas LNA48 commands
use the hob_sector, hob_lcyl and hob_hcyl registers as explained above.
The decomposition as it stands now will correctly decompose CHS, LBA28
and LBA48 commands into their appropriate registers where the core
IDE/ATAPI layers can deal with them correctly.
See the below point for more information.
(3) We save cmd_fis[7] as ide_state->select, which informs
decisions about if we are using LBA or CHS.
This corrects a bug in AHCI wherein we attempt to set and/or
retrieve the sector number by using ide_set_sector and
ide_get_sector, which depend on the select register to
determine if we are using LBA or CHS.
Without this adjustment, LBA48 read/writes are currently
broken. Thanks to Eniac Zheng @ HP for pointing this out.
(4) Save cmd_fis[11] as ide_state->hob_feature, as defined in SATA 3.2.
(5) For several ATA commands, the sector count register set to 0
is a magic number that means 256 sectors. For LBA48 commands,
this means 65,536 sectors. We drop the magic sector correction
here, and trust the ide core layer to handle the conversion
appropriately, in ide_cmd_lba48_transform(). As it stands,
the current AHCI code is only compliant with LBA28 commands.
By simply removing the magic, it will work with LBA28 and LBA48.
(6) We expand FIS decomposition to include both ATAPI and IDE devices.
We leave the logic of determining if the fields are valid or not
to the respective layers.
This change intends to make it clearer that AHCI is only a
composition mechanism for the FIS packets: the meanings of
the registers is best left to the implementation layers for
those devices.
(7) Forcefully setting the feature, hcyl and lcyl registers for ATAPI
commands is removed.
- The hcyl and lcyl magic present here is valid at boot only,
and should not be overridden for every PACKET command.
- The feature register is defined as valid for the PACKET command,
so we should not suppress it. The ATAPI layer does not even
currently depend on or require 0x01 as mandatory.

This impacts both BMDMA and AHCI HBA interfaces for IDE.
Currently, we confuse the difference between a PRDT having
"0 bytes" and a PRDT having "0 complete sectors."
When we receive an incomplete sector, inconsistent error checking
leads to an infinite loop wherein the call succeeds, but it
didn't give us enough bytes -- leading us to re-call the
DMA chain over and over again. This leads to, in the BMDMA case,
leaked memory for short PRDTs, and infinite loops and resource
usage in the AHCI case.
The .prepare_buf() callback is reworked to return the number of
bytes that it successfully prepared. 0 is a valid, non-error
answer that means the table was empty and described no bytes.
-1 indicates an error.
Our current implementation uses the io_buffer in IDEState to
ultimately describe the size of a prepared scatter-gather list.
Even though the AHCI PRDT/SGList can be as large as 256GiB, the
AHCI command header limits transactions to just 4GiB. ATA8-ACS3,
however, defines the largest transaction to be an LBA48 command
that transfers 65,536 sectors. With a 512 byte sector size, this
is just 32MiB.
Since our current state structures use the int type to describe
the size of the buffer, and this state is migrated as int32, we
are limited to describing 2GiB buffer sizes unless we change the
migration protocol.
For this reason, this patch begins to unify the assertions in the
IDE pathways that the scatter-gather list provided by either the
AHCI PRDT or the PCI BMDMA PRDs can only describe, at a maximum,
2GiB. This should be resilient enough unless we need a sector
size that exceeds 32KiB.
Further, the likelihood of any guest operating system actually
attempting to transfer this much data in a single operation is
very slim.
To this end, the IDEState variables have been updated to more
explicitly clarify our maximum supported size. Callers to the
prepare_buf callback have been reworked to understand the new
return code, and all versions of the prepare_buf callback have
been adjusted accordingly.
Lastly, the ahci_populate_sglist helper, relied upon by the
AHCI implementation of .prepare_buf() as well as the PCI
implementation of the callback have had overflow assertions
added to help make clear the reasonings behind the various
type changes.

The intent of this patch is to further unify the creation and
deletion of the sglist used for all AHCI transfers, including
emulated PIO, ATAPI R/W, and native DMA R/W.
By replacing ahci_start_transfer's call to ahci_populate_sglist
with ahci_dma_prepare_buf, we reduce the number of direct calls
where we manipulate the scatter-gather list in the AHCI code.
To make this switch, the constant "0" passed as an offset
in ahci_dma_prepare_buf is adjusted to use io_buffer_offset.
For DMA pathways, this has no effect: io_buffer_offset is always
updated to 0 at the beginning of a DMA transfer loop regardless.
DMA pathways through ide_dma_cb() update the io_buffer_offset
accordingly, and for circumstances where we might make several
trips through this loop, this may actually correct a design flaw.
For PIO pathways, the newly updated ahci_dma_prepare_buf will
now prepare the sglist at the correct offset. It will also set
io_buffer_size, but this is not used in the cmd_read_pio or
cmd_write_pio pathways.

Currently, for emulated PIO transfers through the AHCI device,
any attempt made to request more than a single sector's worth
of data will result in the same sector being transferred over
and over.
For example, if we request 8 sectors via PIO READ SECTORS, the
AHCI device will give us the same sector eight times.
This patch adds offset tracking into the PIO pathways so that
we can fulfill these requests appropriately.

This patch fixes a regression caused by commit
659142ecf7.
The problem occurs when we wish to return early
from the ahci_start_transfer function, but are now
updating the transferred byte count in the AHCI
command header via ahci_commit_buf.
This will cause problems in the Windows 8 installer.
Don't update the byte count in the command header
for the transmission of ATAPI packets: These commands
will distort the final byte count of the actual data
payload.
The call to ahci_commit_buf remains in the "out"
portion of the call in order to clean up the sglist.
The byte count is maintained by forcing size to be 0.

The 'QemuConsole' is the input source for handler, we share some
input handlers to process the input events from different QemuConsole.
Normally we only have one set of keyboard, mouse, usbtablet, etc.
The devices have different mask, it's fine to just checking mask to
insure that the handler has the ability to process the event.
I saw we try to bind console to handler in usb/dev-hid.c, but display
always isn't available at that time.
If we have multiseat setup (as Gerd said), we only have 'problem' in
this case. Actually event from different devices have the same effect
for system, it's fine to always use the first available handler
without caring about the console.
For send-key command, we just pass a NULL for console parameter in
calling qemu_input_event_send_key(NULL, ..), but 'input-send-event'
needs to care more devices.
Conclusion:
Generally assigning the special console is meanless, and we can't
directly remove the QMP parameter for compatibility.
So we can make the parameter optional. The parameter might be useful
for some special condition: we have multiple devices without binding
console and they all have the ability(mask) to process events, and
we don't want to use the first one.

In xen_hvm_change_state_handler(), we can pass 'opaque' with type cast
to xen_main_loop_prepare() directly, there's no need to use additional
variable for it.

bootdevice.c was created by me, and I wrote most of
the code in this file. And now I can maintain it,
I'd hope nobody object this.

This is a simple patch to change the type of old_env from jmp_buf
to sigjmp_buf. old_env is used by sigsetjmp and as such should be
a sigjmp_buf.
This fixes a stack_chk fail in a OSX 32bit build. Since at least on
OSX sigjmp_buf is four bytes larger then a jmpbuf, resulting in an
overflow in sigsetjmp. Due to variable reordering this overwrites
the stack cookie.

Peter: I think I must have missed this one when I converted
all the jmp_buf to sigjmp_buf in commit 6ab7e546.
