We use that Python to create a virtual environment with the "check-venv" target in tests/Makefile.include. $(TESTS_PYTHON) points to the Python executable belonging to the virtual environment tied to the build. This Python executable is a symlink to the binary used to create the venv, which will be the version provided at configure time. Using $(TESTS_PYTHON) therefore uses the $(PYTHON) executable, but with paths modified to use packages installed to the venv.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | module_kconfig is a new directive that should be used with module_obj whenever that module depends on the Kconfig to be enabled. When the module is enabled in Kconfig we are sure that its dependencies will be enabled as well, thus the module will be loaded without any problem.

| * target/i386/tcg: Fix masking of real-mode addresses with A20 bitStephen Michael Jothen2022-06-061-1/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | The correct A20 masking is done if paging is enabled (protected mode) but it seems to have been forgotten in real mode. For example from the AMD64 APM Vol. 2 section 1.2.4: > If the sum of the segment base and effective address carries over into bit 20, > that bit can be optionally truncated to mimic the 20-bit address wrapping of the > 8086 processor by using the A20M# input signal to mask the A20 address bit. Most BIOSes will enable the A20 line on boot, but I found by disabling the A20 line afterwards, the correct wrapping wasn't taking place. `handle_mmu_fault' in target/i386/tcg/sysemu/excp_helper.c seems to be the culprit. In real mode, it fills the TLB with the raw unmasked address. However, for the protected mode, the `mmu_translate' function does the correct A20 masking. The fix then should be to just apply the A20 mask in the first branch of the if statement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NVMe command set specification for end-to-end data protection formatted namespace states: o If the Reference Tag Check bit of the PRCHK field is set to ‘1’ and the namespace is formatted for Type 3 protection, then the controller: ▪ should not compare the protection Information Reference Tag field to the computed reference tag; and ▪ may ignore the ILBRT and EILBRT fields. If a command is aborted as a result of the Reference Tag Check bit of the PRCHK field being set to ‘1’, then that command should be aborted with a status code of Invalid Protection Information, but may be aborted with a status code of Invalid Field in Command. Currently qemu compares reftag in the nvme_dif_prchk function whenever Reference Tag Check bit is set in the command. For type 3 namespaces however, caller of nvme_dif_prchk - nvme_dif_check does not increment reftag for each subsequent logical block. That way commands incorporating more than one logical block for type 3 formatted namespaces with reftag check bit set, always fail with End-to-end Reference Tag Check Error. Comply with spec by handling case of set Reference Tag Check bit in the type 3 formatted namespace.
