Expansion of [*] suffix is very slow because index expansion is done using
trial and error strategy, starting every time from zero and retrying with
the next index until insertion succeeds. With large number of already added
properties this process takes huge amount of time (O(n^2) complexity).
Some architectures (like ARM) use very large amount of IRQ pins in interrupt
controller models. This flaw makes machine startup extremely slow
(~20 seconds for ARM64 with 32 CPUs). This patch decreases this time down to
~10 seconds.

We're a little too lenient with what we'll let an ATAPI drive handle.
Clamp down on the IDE command execution table to remove CD_OK permissions
from commands that are not and have never been ATAPI commands.
For ATAPI command validity, please see:
- ATA4 Section 6.5 ("PACKET Command feature set")
- ATA8/ACS Section 4.3 ("The PACKET feature set")
- ACS3 Section 4.3 ("The PACKET feature set")
ACS3 has a historical command validity table in Table B.4
("Historical Command Assignments") that can be referenced to find when
a command was introduced, deprecated, obsoleted, etc.
The only reference for ATAPI command validity is by checking that
version's PACKET feature set section.
ATAPI was introduced by T13 into ATA4, all commands retired prior to ATA4
therefore are assumed to have never been ATAPI commands.
Mandatory commands, as listed in ATA8-ACS3, are:
- DEVICE RESET
- EXECUTE DEVICE DIAGNOSTIC
- IDENTIFY DEVICE
- IDENTIFY PACKET DEVICE
- NOP
- PACKET
- READ SECTOR(S)
- SET FEATURES
Optional commands as listed in ATA8-ACS3, are:
- FLUSH CACHE
- READ LOG DMA EXT
- READ LOG EXT
- WRITE LOG DMA EXT
- WRITE LOG EXT
All other commands are illegal to send to an ATAPI device and should
be rejected by the device.
CD_OK removal justifications:
0x06 WIN_DSM Defined in ACS2. Not valid for ATAPI.
0x21 WIN_READ_ONCE Retired in ATA5. Not ATAPI in ATA4.
0x94 WIN_STANDBYNOW2 Retired in ATA4. Did not coexist with ATAPI.
0x95 WIN_IDLEIMMEDIATE2 Retired in ATA4. Did not coexist with ATAPI.

Symptom:
$ qemu-system-x86_64 -m 10000000
Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
Aborted (core dumped)
Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions. Before the commit, we report the error and exit(1), in
one place, ram_block_add(). The commit lifts the error handling up
the call chain some, to three places. Fine. Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".
The three places are:
* memory_region_init_ram()
Commit 4994653 (right after commit ef701d7) lifted the error
handling further, through memory_region_init_ram(), multiplying the
incorrect use of &error_abort. Later on, imitation of existing
(bad) code may have created more.
* memory_region_init_ram_ptr()
The &error_abort is still there.
* memory_region_init_rom_device()
Doesn't need fixing, because commit 33e0eb5 (soon after commit
ef701d7) lifted the error handling further, and in the process
changed it from &error_abort to passing it up the call chain.
Correct, because the callers are realize() methods.
Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:
@r@
expression mr, owner, name, size, err;
position p;
@@
memory_region_init_ram(mr, owner, name, size,
(
- &error_abort
+ &error_fatal
|
err@p
)
);
@script:python@
p << r.p;
@@
print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)
When the last argument is &error_abort, it gets replaced by
&error_fatal. This is the fix.
If the last argument is anything else, its position is reported. This
lets us check the fix is complete. Four positions get reported:
* ram_backend_memory_alloc()
Error is passed up the call chain, ultimately through
user_creatable_complete(). As far as I can tell, it's callers all
handle the error sanely.
* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()
DeviceClass.realize() methods, errors handled sanely further up the
call chain.
We're good. Test case again behaves:
$ qemu-system-x86_64 -m 10000000
qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory

IDEState's io_buffer_offset was originally added to keep track of offsets
in AHCI rather exclusively, but it was added to IDEState instead of an
AHCI-specific structure.
AHCI fakes all PIO transfers using DMA and a scatter-gather list. When
the core or atapi layers invoke HBA-specific mechanisms for transfers,
they do not always know that it is being backed by DMA or a sglist, so
this offset is not always updated by the HBA code everywhere.
If we modify it in dma_buf_commit, however, any HBA that needs to use
this offset to manage operating on only part of a sglist will have
access to it.
This will fix ATAPI PIO transfers performed through the AHCI HBA,
which were previously not modifying this value appropriately.
This will fix ATAPI PIO transfers larger than one sector.

Return false from can_receive() when the FIFO doesn't have a free RX
slot. This fixes a bug in the current code where the allocated buffer
is freed before the fifo pop, triggering a premature flush of queued RX
packets. It also will handle a corner case, where the guest manually
frees the allocated buffer before popping the rx FIFO (hence it is not
enough to just delay the flush_queued_packets()).
