13606b9951 sd: Don't trace SDRequest crc field
We don't actually implement SD command CRC checking, because
for almost all of our SD controllers the CRC generation is
done in hardware, and so modelling CRC generation and checking
would be a bit pointless. (The exception is that milkymist-memcard
makes the guest software compute the CRC.)

As a result almost all of our SD controller models don't bother
to set the SDRequest crc field, and the SD card model doesn't
check it. So the tracing of it in sdbus_do_command() provokes
Coverity warnings about use of uninitialized data.

Drop the CRC field from the trace; we can always add it back
if and when we do anything useful with the CRC.

Fixes Coverity issues 1386072, 1386074, 1386076, 1390571.

Spec v2.00 introduces the SEND_IF_COND command:

  6.4.1 Power Up

    CMD8 is newly added in the Physical Layer Specification Version
    2.00 to support multiple voltage ranges and used to check whether
    the card supports supplied voltage. The version 2.00 or later host
    shall issue CMD8 and verify voltage before card initialization.
    The host that does not support CMD8 shall supply high voltage range.

9e1245795f sdcard: Update the Configuration Register (SCR) to Spec Version 1.10
The initial implementation is based on the Specs v1.10 (see a1bb27b1e9).

However the SCR is anouncing the card being v1.01.

The new chapters added in version 1.10 are:

    4.3.10 Switch function command

    Switch function command (CMD6) 1 is used to switch or expand
    memory card functions. [...]
    This is a new feature, introduced in SD physical Layer
    Specification Version 1.10. Therefore, cards that are
    compatible with earlier versions of the spec do not support
    it. The host shall check the "SD_SPEC" field in the SCR
    register to recognize what version of the spec the card
    complies with before using CMD6. It is mandatory for SD
    memory card of Ver1.10 to support CMD6.

    4.3.11 High-Speed mode (25MB/sec interface speed)

    Though the Rev 1.01 SD memory card supports up to 12.5MB/sec
    interface speed, the speed of 25MB/sec is necessary to support
    increasing performance needs of the host and because of memory
    size which continues to grow.
    To achieve 25MB/sec interface speed, clock rate is increased to
    50MHz and CLK/CMD/DAT signal timing and circuit conditions are
    reconsidered and changed from Physical Layer Specification
    Version 1.01.

    4.3.12 Command system (This chapter is newly added in version 1.10)

    SD commands CMD34-37, CMD50, CMD57 are reserved for SD command
    system expansion via the switch command.
    [These commands] will be considered as illegal commands (as
    defined in revision 1.01 of the SD physical layer specification).

The SWITCH_FUNCTION is implemented since the first commit, a1bb27b1e9.

The 25MB/sec High-Speed mode was already updated in d7ecb86752.

The current implementation does not implements CMD34-37, CMD50 and
CMD57, thus these commands already return ILLEGAL.

With this patch, the SCR register now matches the description of the header:

 * SD Memory Card emulation as defined in the "SD Memory Card Physical
 * layer specification, Version 1.10."

f6fb1f9b31 sdcard: Correct CRC16 offset in sd_function_switch()
Per the Physical Layer Simplified Spec. "4.3.10.4 Switch Function Status":

  The block length is predefined to 512 bits

and "4.10.2 SD Status":

  The SD Status contains status bits that are related to the SD Memory Card
  proprietary features and may be used for future application-specific usage.
  The size of the SD Status is one data block of 512 bit. The content of this
  register is transmitted to the Host over the DAT bus along with a 16-bit CRC.

Thus the 16-bit CRC goes at offset 64.

f3d9fe8f95 hw/sd/bcm2835_sdhost: Don't raise spurious interrupts
The Linux bcm2835_sdhost driver doesn't work on QEMU, because our
model raises spurious data interrupts.  Our function
bcm2835_sdhost_fifo_run() will flag an interrupt any time it is
called with s->datacnt == 0, even if the host hasn't actually issued
a data read or write command yet.  This means that the driver gets a
spurious data interrupt as soon as it enables IRQs and then does
something else that causes us to call the fifo_run routine, like
writing to SDHCFG, and before it does the write to SDCMD to issue the
read.  The driver's IRQ handler then spins forever complaining that
there's no data and the SD controller isn't in a state where there's
going to be any data:

[   41.040738] sdhost-bcm2835 3f202000.mmc: fsm 1, hsts 00000000
[   41.042059] sdhost-bcm2835 3f202000.mmc: fsm 1, hsts 00000000
(continues forever).

Move the interrupt flag setting to more plausible places:
 * for BUSY, raise this as soon as a BUSYWAIT command has executed
 * for DATA, raise this when the FIFO has any space free (for a write)
   or any data in it (for a read)
 * for BLOCK, raise this when the data count is 0 and we've
   actually done some reading or writing

This is pure guesswork since the documentation for this hardware is
not public, but it is sufficient to get the Linux bcm2835_sdhost
driver to work.

While there, separate #include from file comment with a blank line,

ecd219f7ab hw/sd/omap_mmc: Reset SD card on controller reset
Since omap_mmc is still using the legacy SD card API, the SD
card created by sd_init() is not plugged into any bus. This
means that the controller has to reset it manually.

Failing to do this mostly didn't affect the guest since the
guest typically does a programmed SD card reset as part of
its SD controller driver initialization, but would mean that
migration fails because it's only in sd_reset() that we
set up the wpgrps_size field.

In the case of sd-ssi, we have to implement an entire

that requires a QOM cast macro that got omitted when this
device was QOMified.

fd3b02c889 pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:

1) The ones that already have INTERFACE_PCIE_DEVICE set:

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3

2) base-pci-bridge

Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:

* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge

The direct subtypes of base-pci-bridge not touched by this patch
are:

* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
  marked as PCIe-only devices.

3) megasas-base

Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.

"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

e4f4fb1eca sysbus: Set user_creatable=false by default on TYPE_SYS_BUS_DEVICE
commit 33cd52b5d7 unset
cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all
sysbus devices appear on "-device help" and lack the "no-user"
flag in "info qdm".

To fix this, we can set user_creatable=false by default on
TYPE_SYS_BUS_DEVICE, but this requires setting
user_creatable=true explicitly on the sysbus devices that
actually work with -device.

Fortunately today we have just a few has_dynamic_sysbus=1
machines: virt, pc-q35-*, ppce500, and spapr.

virt, ppce500, and spapr have extra checks to ensure just a few
device types can be instantiated:

* virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE.
* ppce500 supports only TYPE_ETSEC_COMMON.
* spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE.

This patch sets user_creatable=true explicitly on those 4 device
classes.

Now, the more complex cases:

pc-q35-*: q35 has no sysbus device whitelist yet (which is a
separate bug). We are in the process of fixing it and building a
sysbus whitelist on q35, but in the meantime we can fix the
"-device help" and "info qdm" bugs mentioned above. Also, despite
not being strictly necessary for fixing the q35 bug, reducing the
list of user_creatable=true devices will help us be more
confident when building the q35 whitelist.

xen: We also have a hack at xen_set_dynamic_sysbus(), that sets
has_dynamic_sysbus=true at runtime when using the Xen
accelerator. This hack is only used to allow xen-backend devices
to be dynamically plugged/unplugged.

This means today we can use -device with the following 22 device
types, that are the ones compiled into the qemu-system-x86_64 and
qemu-system-i386 binaries:

* allwinner-ahci
* amd-iommu
* cfi.pflash01
* esp
* fw_cfg_io
* fw_cfg_mem
* generic-sdhci
* hpet
* intel-iommu
* ioapic
* isabus-bridge
* kvmclock
* kvm-ioapic
* kvmvapic
* SUNW,fdtwo
* sysbus-ahci
* sysbus-fdc
* sysbus-ohci
* unimplemented-device
* virtio-mmio
* xen-backend
* xen-sysdev

This patch adds user_creatable=true explicitly to those devices,
temporarily, just to keep 100% compatibility with existing
behavior of q35. Subsequent patches will remove
user_creatable=true from the devices that are really not meant to
user-creatable on any machine, and remove the FIXME comment from
the ones that are really supposed to be user-creatable. This is
being done in separate patches because we still don't have an
obvious list of devices that will be whitelisted by q35, and I
would like to get each device reviewed individually.

e90f2a8c3e qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.

When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.

Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

Except for code comments, changes were generated using the
following Coccinelle patch:

59046ec29a migration: consolidate VMStateField.start
The member VMStateField.start is used for two things, partial data
migration for VBUFFER data (basically provide migration for a
sub-buffer) and for locating next in QTAILQ.

The implementation of the VBUFFER feature is broken when VMSTATE_ALLOC
is used. This however goes unnoticed because actually partial migration
for VBUFFER is not used at all.

Let's consolidate the usage of VMStateField.start by removing support
for partial migration for VBUFFER.

12c125cba9 sd: Switch to byte-based block access
Sector-based blk_write() should die; switch to byte-based
blk_pwrite() instead.  Likewise for blk_read().

Greatly simplifies the code, now that we let the block layer
take care of alignment and read-modify-write on our behalf :)
In fact, we no longer need to include 'buf' in the migration
stream (although we do have to ensure that the stream remains
compatible).

73bcb24d93 Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND
This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed.  This replacement improves the readability and
understandability of code.

For example,

    timer_mod(fdctrl->result_timer,
	      qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

fec44a8c70 sd: Fix "info qtree" on boards with SD cards
The SD card object is not a SysBusDevice, so don't create it with
qdev_create() if we're not assigning it to a specific bus; use
object_new() instead.

This was causing 'info qtree' to segfault on boards with SD cards,
because qdev_create(NULL, TYPE_FOO) puts the created object on the
system bus, and then we may try to run functions like sysbus_dev_print()
on it, which fail when casting the object to SysBusDevice.

(This is the same mistake that we made with the NAND device
and fixed in commit 6749695eaaf346c1.)

0719e71e52 sd.c: Handle NULL block backend in sd_get_inserted()
The sd.c SD card emulation code can be in a state where the
SDState BlockBackend pointer is NULL; this is treated as
"card not present". Add a missing check to sd_get_inserted()
so that we don't segfault in this situation.

(This could be provoked by the guest writing to the SDHCI
register to do a reset on a xilinx-zynq-a9 board; it will
also happen at startup when sdhci implements its DeviceClass
reset method.)

0a7ac9f9e7 sdhci: add quirk property for card insert interrupt status on Raspberry Pi
This quirk is a workaround for the following hardware behaviour, on
which UEFI (specifically, the bootloader for Windows on Pi2) depends:

1. at boot with an SD card present, the interrupt status/enable
   registers are initially zero
2. upon enabling it in the interrupt enable register, the card insert
   bit in the interrupt status register is immediately set
3. after a subsequent controller reset, the card insert interrupt does
   not fire, even if enabled in the interrupt enable register

5c1bc9a234 sdhci: Revert "add optional quirk property to disable card insertion/removal interrupts"
This reverts commit 723697551a.

This change was poorly tested on my part. It squelched card insertion
interrupts on reset, but that was not necessary because sdhci_reset()
clears all the registers (via the call to memset), so the subsequent
sdhci_insert_eject_cb() call never sees the card insert interrupt
enabled. However, not calling the insert_eject_cb results in prnsts
remaining 0, when it actually needs to be updated to indicate card
presence and R/O status.

dd26eb4333 hw/sd: model a power-up delay, as a workaround for an EDK2 bug
The SD spec for ACMD41 says that a zero argument is an "inquiry"
ACMD41, which does not start initialisation and is used only for
retrieving the OCR. However, Tianocore EDK2 (UEFI) has a bug [1]: it
first sends an inquiry (zero) ACMD41. If that first request returns an
OCR value with the power up bit (0x80000000) set, it assumes the card
is ready and continues, leaving the card in the wrong state. (My
assumption is that this works on hardware, because no real card is
immediately powered up upon reset.)

This change models a delay of 0.5ms from the first ACMD41 to the power
being up. However, it also immediately sets the power on upon seeing a
non-zero (non-enquiry) ACMD41. This speeds up UEFI boot, it should
also account for guests that simply delay after card reset and then
issue an ACMD41 that they expect will succeed.

c759a790b6 hw/sd: Add QOM bus which SD cards plug in to
Add a QOM bus for SD cards to plug in to.

Note that since sd_enable() is used only by one board and there
only as part of a broken implementation, we do not provide it in
the SDBus API (but instead add a warning comment about the old
function). Whoever converts OMAP and the nseries boards to QOM
will need to either implement the card switch properly or move
the enable hack into the OMAP MMC controller model.

In the SDBus API, the old-style use of sd_set_cb to register some
qemu_irqs for notification of card insertion and write-protect
toggling is replaced with methods in the SDBusClass which the
card calls on status changes and methods in the SDClass which
the controller can call to find out the current status. The
query methods will allow us to remove the abuse of the 'register
irqs' API by controllers in their reset methods to trigger
the card to tell them about the current status again.
