2020-03-17lockable: add QemuRecMutex supportStefan Hajnoczi
The polymorphic locking macros don't support QemuRecMutex yet. Add it so that lock guards can be used with QemuRecMutex. Convert TCG plugins functions that benefit from these macros. Manual qemu_rec_mutex_lock/unlock() callers are left unmodified in cases where clarity would not improve by switching to the macros.

2020-03-17lockable: add lock guardsStefan Hajnoczi
This patch introduces two lock guard macros that automatically unlock a lock object (QemuMutex and others): void f(void) { QEMU_LOCK_GUARD(&mutex); if (!may_fail()) { return; /* automatically unlocks mutex */ } ... } and: WITH_QEMU_LOCK_GUARD(&mutex) { if (!may_fail()) { return; /* automatically unlocks mutex */ } } /* automatically unlocks mutex here */ ... Convert qemu-timer.c functions that benefit from these macros as an example. Manual qemu_mutex_lock/unlock() callers are left unmodified in cases where clarity would not improve by switching to the macros. Many other QemuMutex users remain in the codebase that might benefit from lock guards. Over time they can be converted, if that is desirable.

2020-03-17lockable: add QEMU_MAKE_LOCKABLE_NONNULLPaolo Bonzini
This will be needed for lock guards, because if the lock is NULL the dummy for loop of the lock guard never runs. This can cause confusion and dummy warnings in the compiler, but even if it did not, aborting with a NULL pointer dereference is a less surprising behavior.

2020-03-17aspeed/smc: Fix number of dummy cycles for FAST_READ_4 commandGuenter Roeck
The Linux kernel recently started using FAST_READ_4 commands. This results in flash read failures. At the same time, the m25p80 emulation is seen to read 8 more bytes than expected. Adjusting the expected number of dummy cycles to match FAST_READ fixes the problem.

2020-03-17m25p80: Improve command handling for unsupported commandsGuenter Roeck
Whenever an unsupported command is encountered, the current code interprets each transferred byte as new command. Most of the time, those 'commands' are interpreted as new unknown commands. However, in rare cases, it may be that for example address or length information passed with the original command is by itself a valid command. If that happens, the state machine may get completely confused and, worst case, start writing data into the flash or even erase it. To avoid the problem, transition into STATE_READING_DATA and keep sending a value of 0 until the chip is deselected after encountering an unsupported command.

2020-03-17m25p80: Improve command handling for Jedec commandsGuenter Roeck
When requesting JEDEC data using the JEDEC_READ command, the Linux kernel always requests 6 bytes.

To avoid the problem, always report up to 6 bytes of JEDEC data. Fill remaining data with 0.

2020-03-17Merge remote-tracking branch 'remotes/palmer/tags/riscv-for-master-5.0-sf5' ↵Peter Maydell
into staging RISC-V Patches for the 5.0 Soft Freeze, Part 5 This tag contains the last of the patches I'd like to target for the 5.0 soft freeze. At this point we're mostly collecting fixes, but there are a few new features. The changes include: * An OpenSBI update, including the various bits necessary to put CI together and an image for the 32-bit sifive_u board. * A fix that disallows TSR when outside of machine mode. * A fix for VS-mode interrupt forwarding. # gpg: Signature made Tue 17 Mar 2020 03:59:58 GMT # gpg: using RSA key 2B3C3747446843B24A943A7A2E1319F35FBB1889 # gpg: issuer "palmer@dabbelt.com" # gpg: Good signature from "Palmer Dabbelt <palmer@dabbelt.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmer@sifive.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmerdabbelt@google.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 00CE 76D1 8349 60DF CE88 6DF8 EF4C A150 2CCB AB41 # Subkey fingerprint: 2B3C 3747 4468 43B2 4A94 3A7A 2E13 19F3 5FBB 1889 * remotes/palmer/tags/riscv-for-master-5.0-sf5: target/riscv: Fix VS mode interrupts forwarding. gitlab-ci.yml: Add jobs to build OpenSBI firmware binaries riscv: sifive_u: Update BIOS_FILENAME for 32-bit roms: opensbi: Add 32-bit firmware image for sifive_u machine roms: opensbi: Upgrade from v0.5 to v0.6 target/riscv: Correctly implement TSR trap Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2020-03-17usb-serial: Fix timeout closing the deviceJason Andryuk
Linux guests wait ~30 seconds when closing the emulated /dev/ttyUSB0. During that time, the kernel driver is sending many control URBs requesting GetModemStat (5). Real hardware returns a status with FTDI_THRE (Transmitter Holding Register) and FTDI_TEMT (Transmitter Empty) set. QEMU leaves them clear, and it seems Linux is waiting for FTDI_TEMT to be set to indicate the tx queue is empty before closing. Set the bits when responding to a GetModemStat query and avoid the shutdown delay.

2020-03-17usb-serial: Increase receive buffer to 496Jason Andryuk
A FTDI USB adapter on an xHCI controller can send 512 byte USB packets. These are 8 * ( 2 bytes header + 62 bytes data). A 384 byte receive buffer is insufficient to fill a 512 byte packet, so bump the receive size to 496 ( 512 - 2 * 8 ).
