2022-03-04hw/usb/redirect.c: Stop using qemu_oom_check()Peter Maydell
qemu_oom_check() is a function which essentially says "if you pass me a NULL pointer then print a message then abort()". On POSIX systems the message includes strerror(errno); on Windows it includes the GetLastError() error value printed as an integer. Other than in the implementation of qemu_memalign(), we use this function only in hw/usb/redirect.c, for three checks: * on a call to usbredirparser_create() * on a call to usberedirparser_serialize() * on a call to malloc() The usbredir library API functions make no guarantees that they will set errno on errors, let alone that they might set the Windows-specific GetLastError string. malloc() is documented as setting errno, not GetLastError -- and in any case the only thing it might set errno to is ENOMEM. So qemu_oom_check() isn't the right thing for any of these. Replace them with straightforward error-checking code. This will allow us to get rid of qemu_oom_check().

Now that the mixing buffer size no longer adds to playback latency, fix the samples vs. frames mix-up in the mixing buffer size calculation. This change will go largely unnoticed as long as the user doesn't use a buffer-size smaller than timer-period.

2022-03-04audio: restore mixing-engine playback buffer sizeVolker Rümelin
Commit ff095e5231 "audio: api for mixeng code free backends" introduced another FIFO for the audio subsystem with exactly the same size as the mixing-engine FIFO. Most audio backends use this generic FIFO. The generic FIFO used together with the mixing-engine FIFO doubles the audio FIFO size, because that's just two independent FIFOs connected together in series. For audio playback this nearly doubles the playback latency. This patch restores the effective mixing-engine playback buffer size to a pre v4.2.0 size by only accepting the amount of samples for the mixing-engine queue which the downstream queue accepts.

2022-03-04audio: copy playback stream in sequential orderVolker Rümelin
Change the code to copy the playback stream in sequential order. The advantage can be seen in the next patches where the stream copy operation effectively becomes a write through operation. The following diagram shows the average buffer fill level and the stream copy sequence. ### represents a timer_period sized chunk. The rest of the buffer sizes are not to scale.

2022-03-04jackaudio: use more jack audio buffersVolker Rümelin
The next patch reduces the effective qemu playback buffer size by timer-period. Increase the number of jack audio buffers by one to preserve the total effective buffer size. The size of one jack audio buffer is 512 samples. With audio defaults that's 512 samples / 44100 samples/s = 11.6 ms and only slightly larger than the timer-period of 10 ms. The larger jack audio buffer increases audio dropout safety, because the high priority jack-audio worker threads can provide audio data for a longer period of time as with a smaller buffer and more audio data in the mixing engine buffer that they can't access.

2022-03-04usb/ohci: Don't use packet from OHCIState for isochronous transfersBALATON Zoltan
Since isochronous transfers cannot be handled async (the function returns error in that case) we don't need to remember the packet. Avoid using the usb_packet field in OHCIState (as that can be a waiting async packet on another endpoint) and allocate and use a local USBPacket for the iso transfer instead. After this we don't have to care if we're called from a completion callback or not so we can drop that parameter as well.

2022-03-03hw/nvme: 64-bit pi supportNaveen Nagar
This adds support for one possible new protection information format introduced in TP4068 (and integrated in NVMe 2.0): the 64-bit CRC guard and 48-bit reference tag. This version does not support storage tags. Like the CRC16 support already present, this uses a software implementation of CRC64 (so it is naturally pretty slow). But its good enough for verification purposes. This may go nicely hand-in-hand with the support that Keith submitted for the Linux kernel[1].

2022-03-03hw/riscv: virt: Increase maximum number of allowed CPUsAnup Patel
To facilitate software development of RISC-V systems with large number of HARTs, we increase the maximum number of allowed CPUs to 512 (2^9). We also add a detailed source level comments about limit defines which impact the physical address space utilization.

2022-03-03hw/riscv: virt: Add optional AIA IMSIC support to virt machineAnup Patel
We extend virt machine to emulate both AIA IMSIC and AIA APLIC devices only when "aia=aplic-imsic" parameter is passed along with machine name in the QEMU command-line. The AIA IMSIC is only a per-HART MSI controller so we use AIA APLIC in MSI-mode to forward all wired interrupts as MSIs to the AIA IMSIC. We also provide "aia-guests=<xyz>" parameter which can be used to specify number of VS-level AIA IMSIC Guests MMIO pages for each HART.

2022-03-03hw/intc: Add RISC-V AIA IMSIC device emulationAnup Patel
The RISC-V AIA (Advanced Interrupt Architecture) defines a new interrupt controller for MSIs (message signal interrupts) called IMSIC (Incoming Message Signal Interrupt Controller). The IMSIC is per-HART device and also suppport virtualizaiton of MSIs using dedicated VS-level guest interrupt files. This patch adds device emulation for RISC-V AIA IMSIC which supports M-level, S-level, and VS-level MSIs.
