2019-01-11qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini
Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2018-01-23hw/block: Fix pin-based interrupt behaviour of NVMeHikaru Nishida
Pin-based interrupt of NVMe controller did not work properly because using an obsolated function pci_irq_pulse(). To fix this, change to use pci_irq_assert() / pci_irq_deassert() instead of pci_irq_pulse().

2017-06-26nvme: Add support for Read Data and Write Data in CMBs.Stephen Bates
Add the ability for the NVMe model to support both the RDS and WDS modes in the Controller Memory Buffer. Although not currently supported in the upstreamed Linux kernel a fork with support exists [1] and user-space test programs that build on this also exist [2]. Useful for testing CMB functionality in preperation for real CMB enabled NVMe devices (coming soon).

2017-05-26nvme: Add support for Controller Memory BuffersStephen Bates
Implement NVMe Controller Memory Buffers (CMBs) which were added in version 1.2 of the NVMe Specification. This patch adds an optional argument (cmb_size_mb) which indicates the size of the CMB (in MB). Currently only the Submission Queue Support (SQS) is enabled which aligns with the current Linux driver for NVMe.

Move declarations out of qemu-common.h for functions declared in utils/ files: e.g. include/qemu/path.h for utils/path.c.

2015-07-14nvme: implement the Flush commandChristoph Hellwig
Implement a real flush instead of faking it. This is especially important as Qemu assume Write back cashing by default and thus requires a working cache flush operation for data integrity.

2013-06-17NVMe: Initial commit for new storage interfaceKeith Busch
Initial commit for emulated Non-Volatile-Memory Express (NVMe) pci storage device. NVMe is an open, industry driven storage specification defining an optimized register and command set designed to deliver the full capabilities of non-volatile memory on PCIe SSDs. Further information may be found on the organizations website at: http://www.nvmexpress.org/ This commit implements the minimum from the specification to work with existing drivers.
