aspeed/timer: use the APB frequency from the SCU

The timer controller can be driven by either an external 1MHz clock or
by the APB clock. Today, the model makes the assumption that the APB
frequency is always set to 24MHz but this is incorrect.

The AST2400 SoC on the palmetto machines uses a 48MHz input clock
source and the APB can be set to 48MHz. The consequence is a general
system slowdown. The QEMU machines using the AST2500 SoC do not seem
impacted today because the APB frequency is still set to 24MHz.

We fix the timer frequency for all SoCs by linking the Timer model to
the SCU model. The APB frequency driving the timers is now the one
configured for the SoC.

All Aspeed SoC clocks are driven by an input source clock which can
have different frequencies : 24MHz or 25MHz, and also, on the Aspeed
AST2400 SoC, 48MHz. The H-PLL (CPU) clock is defined from a

(Aspeed AST2400 SoC). The other clocks of the SoC are then defined

target/arm: Handle small regions in get_phys_addr_pmsav8()

Allow ARMv8M to handle small MPU and SAU region sizes, by making
get_phys_add_pmsav8() set the page size to the 1 if the MPU or
SAU region covers less than a TARGET_PAGE_SIZE.

We choose to use a size of 1 because it makes no difference to
the core code, and avoids having to track both the base and
limit for SAU and MPU and then convert into an artificially
restricted "page size" that the core code will then ignore.

Since the core TCG code can't handle execution from small
MPU regions, we strip the exec permission from them so that
any execution attempts will cause an MPU exception, rather
than allowing it to end up with a cpu_abort() in
get_page_addr_code().

(The previous code's intention was to make any small page be
treated as having no permissions, but unfortunately errors
in the implementation meant that it didn't behave that way.
It's possible that some binaries using small regions were
accidentally working with our old behaviour and won't now.)

We also retain an existing bug, where we ignored the possibility
that the SAU region might not cover the entire page, in the
case of executable regions. This is necessary because some
currently-working guest code images rely on being able to
execute from addresses which are covered by a page-sized
MPU region but a smaller SAU region. We can remove this
workaround if we ever support execution from small regions.

ahci: fix FIS I bit and PIO Setup FIS interrupt

The "I" bit in PIO Setup and D2H FISes is exclusively a device concept
and the irqstatus register in the controller does not matter.  The SATA
spec says when it should be one; for D2H FISes in practice it is always
set, while the PIO Setup FIS has several subcases that are documented in
the patch.

Also, the PIO Setup FIS interrupt is actually generated _after_ data
has been received.

Someone should probably spend some time reading the SATA specification and
figuring out the more obscure fields in the PIO Setup FIS, but this is enough
to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.

Igor Mammedov [Wed, 20 Jun 2018 13:24:19 +0000 (15:24 +0200)]
vl.c: do not allow --daemonize in combination with --preconfig CLI option

some users when using --daemonize expect that QEMU will parse CLI options,
initialize VM and only then complete daemonzation by signalling lead
process to exit and start listening on monitor socket. So users treat
parent process exit as sync point to connect to QEMU's monitor.

That however doesn't work when --preconfig options is used, since it
provides monitor before completing daemonization and expects user to
issue exit-preconfig command when additional configuration via monitor
is finished. We also can't move completing daemonization before
preconfig monitor becomes available, since that would imply:
  * partially loosing ability to configure QEMU instance in --preconfig
    mode since QEMU might drop privileges, chroot and do other things
    when daemonization is completed
  * lead to loss of error messages in case they would happen after
    daemonization

Be proactive now and make options mutually exclusive, so users would
get clear error message instead of waiting for lead process exit
indefinitely before connecting to monitor.

PS:
In case someone would come up with usecase where both options should
be enabled at the same time we could drop this restriction as far
as daemonization point is left where it is now (os_setup_post).

audio/hda: create millisecond timers that handle IO

Currently, the HDA device tries to sync itself with the QEMU audio
backend by waiting for the guest driver to handle buffer completion
interrupts. This causes the backend to often read too much data from the
device, as well as running out of data whenever the guest takes too long
to handle the interrupt.

According to the HDA specification, the guest is also not required to
use interrupts, but can also sync itself by polling the LPIB registers.

This patch will introduce high frequency (1000Hz) timers that interface
with the device and allow for much smoother emulation of the LPIB
registers. Since the timing is now provided by these timers, the need
to wait for buffer completion interrupts also ceases.

qapi: Open files with encoding='utf-8'

Python 2 happily reads UTF-8 files in text mode, but Python 3 requires

Since Python 2's open() doesn't support the encoding parameter, we

QDicts that are moved to the root QDict.  It is completely sufficient to
remove all old entries from the root QDict, however.  If the nested
dicts have a refcount of 1, this will automatically delete them, too.
And if they have a greater refcount, we probably do not want to modify
them in the first place.

The latter observation means that it was currently (in general)
impossible to qdict_flatten() a shallowly cloned dict because that would
empty nested QDicts in the original dict as well.  This patch changes
this, so you can now use qdict_flatten(qdict_shallow_clone(dict)) to get

hw/misc/tz-mpc.c: Implement correct blocked-access behaviour

The MPC is guest-configurable for whether blocked accesses:
 * should be RAZ/WI or cause a bus error
 * should generate an interrupt or not

Implement this behaviour in the blocked-access handlers.

6 years agohw/misc/tz-mpc.c: Implement the Arm TrustZone Memory Protection Controller

hw/misc/tz-mpc.c: Implement the Arm TrustZone Memory Protection Controller

Implement the Arm TrustZone Memory Protection Controller, which sits
in front of RAM and allows secure software to configure it to either
pass through or reject transactions.

We implement the MPC as a QEMU IOMMU, which will direct transactions
either through to the devices and memory behind it or to a special
"never works" AddressSpace if they are blocked.

This initial commit implements the skeleton of the device:
 * it always permits accesses
 * it doesn't implement most of the registers
 * it doesn't implement the interrupt or other behaviour
   for blocked transactions
