To: qemu-devel
flash.h's incomplete struct pflash_t is completed both in
pflash_cfi01.c and in pflash_cfi02.c. The complete types are
incompatible. This can hide type errors, such as passing a pflash_t
created with pflash_cfi02_register() to pflash_cfi01_get_memory().
Furthermore, POSIX reserves typedef names ending with _t.
Rename the two structs to PFlashCFI01 and PFlashCFI02.

When a guest tries to abort "write to buffer" (command 0xE8), we print
"PFLASH: Possible BUG - Write block confirm", then exit(1). Letting
the guest terminate QEMU is not a good idea. Instead, LOG_UNIMP we
screwed up, then reset the device.
Macro PFLASH_BUG() is now unused; delete it.

Our implementation of "write to buffer" (command 0xE8) is flawed.
LOG_UNIMP its use, and add some FIXME comments.

We have two open-coded copies of macro PFLASH_CFI01(). Move the macro
to the header, so we can ditch the copies. Move PFLASH_CFI02() to the
header for symmetry.
We define macros TYPE_PFLASH_CFI01 and TYPE_PFLASH_CFI02 for type name
strings, then mostly use the strings. If the macros are worth
defining, they are worth using. Replace the strings by the macros.

To: qemu-devel
Machine "sam460ex" maps its flash memory at address 0xFFF00000. When
no image is supplied, its size is 1MiB (0x100000), and 512KiB of ROM
get mapped on top of its second half. Else, it's the size of the
image rounded up to the next multiple of 64KiB.
The rounding is actually useless: pflash_cfi01_realize() fails with
"failed to read the initial flash content" unless it's a no-op.
I have no idea what happens when the pflash's size exceeds 1MiB.
Useful outcomes seem unlikely.
I guess memory at the end of the address space remains unmapped when
it's smaller than 1MiB. Again, useful outcomes seem unlikely.
The physical hardware appears to have 512KiB of flash memory:
https://eu.mouser.com/datasheet/2/268/atmel_AT49BV040B-1180330.pdf
For now, just set the flash memory size to 1MiB regardless of image
size, and document the mess.

The disabled DEBUG_BOARD_INIT code goes back to the initial commit
1a6c0886203, and has since seen only mechanical updates. It sure
feels like useless clutter now. Delete it.

Machine "ref405ep" maps its flash memory at address 2^32 - image size.
Image size is rounded up to the next multiple of 64KiB. Useless,
because pflash_cfi02_realize() fails with "failed to read the initial
flash content" unless the rounding is a no-op.
If the image size exceeds 0x80000 Bytes, we overlap first SRAM, then
other stuff. No idea how that would play out, but useful outcomes
seem unlikely.
Map the flash memory at fixed address 0xFFF80000 with size 512KiB,
regardless of image size, to match the physical hardware.
Machine "taihu" maps its boot flash memory similarly. The code even
has a comment /* XXX: should check that size is 2MB */, followed by
disabled code to adjust the size to 2MiB regardless of image size.
Its code to map its application flash memory looks the same, except
there the XXX comment asks for 32MiB, and the code to adjust the size
isn't disabled. Note that pflash_cfi02_realize() fails with "failed
to read the initial flash content" for images smaller than 32MiB.
Map the boot flash memory at fixed address 0xFFE00000 with size 2MiB,
to match the physical hardware. Delete dead code from application
flash mapping, and simplify some.

pflash_cfi02_register() takes a size in bytes, a block size in bytes
and a number of blocks. r2d_init() passes FLASH_SIZE, 16 * KiB,
FLASH_SIZE >> 16. Does not compute: size doesn't match block size *
number of blocks. The latter happens to win: FLASH_SIZE / 4,
i.e. 8MiB.
The best information we have on the physical hardware lists a Cypress
S29PL127J60TFI130 128MiBit NOR flash addressable in words of 16 bits,
in sectors of 4 and 32 Kibiwords. We don't model multiple sector
sizes.
Fix the flash size from 8 to 16MiB, and adjust the sector size from 16
to 64KiB. Fix the width from 4 to 2. While there, supply the real
device IDs 0x0001, 0x227e, 0x2220, 0x2200 instead of zeros.

Variable fl_sectors is used just once. Since
fl_sectors = bios_size >> 16 and bios_size = FLASH_SIZE there,
we can simply use FLASH_SIZE >> 16, and eliminate variable.

The 'bios_size' variable is only used in the 'if (!kernel_filename &&
!dinfo)' clause. This is the case when we don't provide -pflash command
line option, and also don't provide a -kernel option. In this case we
will check for the -bios option, or use the default BIOS_FILENAME file.
The 'bios' term is valid in this if statement, but is confuse in the
whole mips_malta_init() scope. Restrict his scope.

pflash_cfi01_register() takes a size in bytes, a block size in bytes
and a number of blocks. mips_malta_init() passes BIOS_SIZE, 65536,
FLASH_SIZE >> 16. Actually consistent only because BIOS_SIZE (defined
in include/hw/mips/bios.h as (4 * MiB)) matches FLASH_SIZE (defined
locally as 0x400000). Confusing all the same.
Pass FLASH_SIZE instead of BIOS_SIZE.

To: qemu-devel
Our pflash devices are simplistically modelled has having
"num-blocks" sectors of equal size "sector-length". Real hardware
commonly has sectors of different sizes. How our "sector-length"
property is related to the physical device's multiple sector sizes
is unclear.
Helper functions pflash_cfi01_register() and pflash_cfi02_register()
create a pflash device, set properties including "sector-length" and
"num-blocks", and realize. They take parameters @size, @sector_len
and @nb_blocs.
QOMification left parameter @size unused. Obviously, @size should
match @sector_len and @nb_blocs, i.e. size == sector_len * nb_blocs.
All callers satisfy this.
Remove @nb_blocs and compute it from @size and @sector_len.

From: Markus Armbruster @ 2019-03-11 22:08 UTC (permalink / raw)
To: qemu-devel; +Cc: Marc-André Lureau
Compatibility properties started life as a qdev property thing: we
supported them only for qdev properties, and implemented them with the
machinery backing command line option -global.
Recent commit fa0cb34d221 put them to use (tacitly) with memory
backend objects (subtypes of TYPE_MEMORY_BACKEND). To make that
possible, we first moved the work of applying them from the -global
machinery into TYPE_DEVICE's .instance_post_init() method
device_post_init(), in commits ea9ce8934c5 and b66bbee39f6, then made
it available to TYPE_MEMORY_BACKEND's .instance_post_init() method
host_memory_backend_post_init() as object_apply_compat_props(), in
commit 1c3994f6d2a.
Note the code smell: we now have function name starting with object_
in hw/core/qdev.c. It has to be there rather than in qom/, because it
calls qdev_get_machine() to find the current accelerator's and
machine's compat_props.
Turns out calling qdev_get_machine() there is problematic. If we
qdev_create() from a machine's .instance_init() method, we call
device_post_init() and thus qdev_get_machine() before main() can
create "/machine" in QOM. qdev_get_machine() tries to get it with
container_get(), which "helpfully" creates it as "container" object,
and returns that. object_apply_compat_props() tries to paper over the
problem by doing nothing when the value of qdev_get_machine() isn't a
TYPE_MACHINE. But the damage is done already: when main() later
attempts to create the real "/machine", it fails with "attempt to add
duplicate property 'machine' to object (type 'container')", and
aborts.
Since no machine .instance_init() calls qdev_create() so far, the bug
is latent. But since I want to do that, I get to fix the bug first.
Observe that object_apply_compat_props() doesn't actually need the
MachineState, only its the compat_props member of its MachineClass and
AccelClass. This permits a simple fix: register MachineClass and
AccelClass compat_props with the object_apply_compat_props() machinery
right after these classes get selected.
This is actually similar to how things worked before commits
ea9ce8934c5 and b66bbee39f6, except we now register much earlier. The
old code registered them only after the machine's .instance_init()
ran, which would've broken compatibility properties for any devices
created there.

main() registers the user's -global only after we create the machine
object, i.e. too late for devices created in the machine's
.instance_init().
Fortunately, we know the bug is only latent: the commit before
previous fixed a bug that would've crashed any attempt to create a
device in an .instance_init().

The first call of sysbus_get_default() creates the main system bus and
stores it in QOM as "/machine/unattached/sysbus". This must not
happen before main() creates "/machine", or else container_get() would
"helpfully" create it as "container" object, and the real creation of
"/machine" would later abort with "attempt to add duplicate property
'machine' to object (type 'container')". Has been that way ever since
we wired up busses in QOM (commit f968fc6892d, v1.2.0).
I believe the bug is latent. I got it to bite by trying to
qdev_create() a sysbus device from a machine's .instance_init()
method.
The fix is obvious: store the main system bus in QOM right after
creating "/machine".

qemu-system-FOO's main() acts on command line arguments in its own
idiosyncratic order. There's not much method to its madness.
Whenever we find a case where one kind of command line argument needs
to refer to something created for another kind later, we rejigger the
order.
Block devices get created long after machine properties get processed.
Therefore, block device machine properties can be created, but not
set. No such properties exist. But the next commit will create some.
Time to rejigger again: create block devices earlier.

To: qemu-devel
The PC machines put firmware in ROM by default. To get it put into
flash memory (required by OVMF), you have to use -drive
if=pflash,unit=0,... and optionally -drive if=pflash,unit=1,...
Why two -drive? This permits setting up one part of the flash memory
read-only, and the other part read/write. It also makes upgrading
firmware on the host easier. Below the hood, it creates two separate
flash devices, because we were too lazy to improve our flash device
models to support sector protection.
The problem at hand is to do the same with -blockdev somehow, as one
more step towards deprecating -drive.
Mapping -drive if=none,... to -blockdev is a solved problem. With
if=T other than if=none, -drive additionally configures a block device
frontend. For non-onboard devices, that part maps to -device. Also a
solved problem. For onboard devices such as PC flash memory, we have
an unsolved problem.
This is actually an instance of a wider problem: our general device
configuration interface doesn't cover onboard devices. Instead, we have
a zoo of ad hoc interfaces that are much more limited. One of them is
-drive, which we'd rather deprecate, but can't until we have suitable
replacements for all its uses.
Sadly, I can't attack the wider problem today. So back to the narrow
problem.
My first idea was to reduce it to its solved buddy by using pluggable
instead of onboard devices for the flash memory. Workable, but it
requires some extra smarts in firmware descriptors and libvirt. Paolo
had an idea that is simpler for libvirt: keep the devices onboard, and
add machine properties for their block backends.
The implementation is less than straightforward, I'm afraid.
First, block backend properties are *qdev* properties. Machines can't
have those, as they're not devices. I could duplicate these qdev
properties as QOM properties, but I hate that.
More seriously, the properties do not belong to the machine, they
belong to the onboard flash devices. Adding them to the machine would
then require bad magic to somehow transfer them to the flash devices.
Fortunately, QOM provides the means to handle exactly this case: add
alias properties to the machine that forward to the onboard devices'
properties.
Properties need to be created in .instance_init() methods. For PC
machines, that's pc_machine_initfn(). To make alias properties work,
we need to create the onboard flash devices there, too. Requires
several bug fixes, in the previous commits. We also have to realize
the devices. More on that below.
If the user sets pflash0, firmware resides in flash memory.
pc_system_firmware_init() maps and realizes the flash devices.
Else, firmware resides in ROM. The onboard flash devices aren't used
then. pc_system_firmware_init() destroys them unrealized, along with
the alias properties.
The existing code to pick up drives defined with -drive if=pflash is
replaced by code to desugar into the machine properties.

The previous commit added a way to configure firmware with -blockdev
rather than -drive if=pflash. Document it as the preferred way.

Actually, there is more problems with this. Trying to run a guest with
persistent reservations fails after this patch is applied (git bisect
points me to this commit). My command line is:
qemu.git $ ./x86_64-softmmu/qemu-system-x86_64 \
-monitor stdio \
-object pr-manager-helper,id=pr-helper0,path=/tmp/pr-helper0.sock
-drive
file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2
\
-device
scsi-block,bus=scsi0.0,channel=0,scsi-id=0,lun=2,drive=drive-scsi0-0-0-2,id=scsi0-0-0-2
Honestly, I have no idea how to fix it, so I'm just raising this issue
here. Do you want me to open a bug or something?
Thanks,

Let's skip the bug filing bureaucracy and go straight to debugging.
Actual and expected behavior of your reproducer, please :)

Agreed.

Actual is that qemu fails to parse cmd line:
qemu-system-x86_64: -drive
file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2:
No persistent reservation manager with id 'pr-helper0'
Which obviously is not correct, because pr-helper0 is specified.
Expected result is that qemu suceeds in parsing the cmd line and starts
the guest. To test it you don't need /dev/mapper/* really, I mean, if
qemu fails with a different error message (e.g. it can't open the disk
or EPERM or whatever), it's a sign it got past the cmd line parsing
successfuly.

main() acts on command line arguments in its own idiosyncratic order.
There's not much method to its madness. Whenever we find a case where
one kind of command line argument needs to refer to something created
for another kind later, we rejigger the order.
Some time back, Dan Berrangé ran into an "impossible" instance of this
general problem: some kinds of -object get referenced by certain
character devices (therefore, -object must be acted on before character
devices), but other kinds of -object reference other character devices
(therefore, -object must be acted on after character devices). He
solved the problem by sorting the -object into two buckets (commit
f08f9271bfe):
* Normal ones are created pretty early, so they can be referenced by
(most) other things.
* Delayed ones are created pretty late, so they can reference (most)
other things.
The pr-manager-helper object is a delayed one (commit 7c9e527659c).
Worked because block backends got created even after delayed objects:
qemu_opts_foreach(qemu_find_opts("object"),
user_creatable_add_opts_foreach,
object_create_initial, &error_fatal);
[...]
qemu_opts_foreach(qemu_find_opts("object"),
user_creatable_add_opts_foreach,
object_create_delayed, &error_fatal);
[...]
configure_blockdev(&bdo_queue, machine_class, snapshot);
Commit cda4aa9a5a0 moved the configure_blockdev() up:
qemu_opts_foreach(qemu_find_opts("object"),
user_creatable_add_opts_foreach,
object_create_initial, &error_fatal);
[...]
/*
* Note: we need to create block backends before
* machine_set_property(), so machine properties can refer to
* them.
*/
configure_blockdev(&bdo_queue, machine_class, snapshot);
[...]
qemu_opts_foreach(qemu_find_opts("object"),
user_creatable_add_opts_foreach,
object_create_delayed, &error_fatal);
Now file-posix property "pr-manager" can no longer reference a
pr-manager-helper object. Regression.
If I make pr-manager-helper a normal object, it again can reference it.
Paolo, why is pr-manager-helper a delayed object? Why this hunk of

I don't think there was any particular reason. Change it back to
normal, I can send a pull request today for that.

This code is inside the "if (dinfo)" condition, so testing again
here whether it is NULL is unnecessary.
