2021-05-13numa: Make all callbacks of ram block notifiers optionalDavid Hildenbrand1-3/+10
Let's make add/remove optional. We want to introduce a RAM block notifier for RAM migration that is only interested in resize events.

2021-05-13numa: Teach ram block notifiers about resizeable ram blocksDavid Hildenbrand2-8/+21
Ram block notifiers are currently not aware of resizes. To properly handle resizes during migration, we want to teach ram block notifiers about resizeable ram. Introduce the basic infrastructure but keep using max_size in the existing notifiers. Supply the max_size when adding and removing ram blocks. Also, notify on resizes.

2021-05-13util: vfio-helpers: Factor out and fix processing of existing ram blocksDavid Hildenbrand1-0/+14
Factor it out into common code when a new notifier is registered, just as done with the memory region notifier. This keeps logic about how to process existing ram blocks at a central place. Just like when adding a new ram block, we have to register the max_length. Ram blocks are only "fake resized". All memory (max_length) is mapped. Print the warning from inside qemu_vfio_ram_block_added().

2021-05-13migrate/ram: remove "ram_bulk_stage" and "fpo_enabled"David Hildenbrand2-6/+1
The bulk stage is kind of weird: migration_bitmap_find_dirty() will indicate a dirty page, however, ram_save_host_page() will never save it, as migration_bitmap_clear_dirty() detects that it is not dirty. We already fill the bitmap in ram_list_init_bitmaps() with ones, marking everything dirty - it didn't used to be that way, which is why we needed an explicit first bulk stage. Let's simplify: make the bitmap the single source of thuth. Explicitly handle the "xbzrle_enabled after first round" case. Regarding XBZRLE (implicitly handled via "ram_bulk_stage = false" right now), there is now a slight change in behavior: - Colo: When starting, it will be disabled (was implicitly enabled) until the first round actually finishes. - Free page hinting: When starting, XBZRLE will be disabled (was implicitly enabled) until the first round actually finished. - Snapshots: When starting, XBZRLE will be disabled. We essentially only do a single run, so I guess it will never actually get disabled. Postcopy seems to indirectly disable it in ram_save_page(), so there shouldn't be really any change.

2021-05-10hw/arm/xlnx: Fix PHY address for xilinx-zynq-a9Guenter Roeck1-1/+1
Commit dfc388797cc4 ("hw/arm: xlnx: Set all boards' GEM 'phy-addr' property value to 23") configured the PHY address for xilinx-zynq-a9 to 23. When trying to boot xilinx-zynq-a9 with zynq-zc702.dtb or zynq-zc706.dtb, this results in the following error message when trying to use the Ethernet interface. macb e000b000.ethernet eth0: Could not attach PHY (-19) The devicetree files for ZC702 and ZC706 configure PHY address 7. The documentation for the ZC702 and ZC706 evaluation boards suggest that the PHY address is 7, not 23. Other boards use PHY address 0, 1, 3, or 7. I was unable to find a documentation or a devicetree file suggesting or using PHY address 23. The Ethernet interface starts working with zynq-zc702.dtb and zynq-zc706.dtb when setting the PHY address to 7, so let's use it.

2021-05-10hw/arm/mps2-tz: Implement AN524 memory remapping via machine propertyPeter Maydell1-1/+107
The AN524 FPGA image supports two memory maps, which differ in where the QSPI and BRAM are. In the default map, the BRAM is at 0x0000_0000, and the QSPI at 0x2800_0000. In the second map, they are the other way around. In hardware, the initial mapping can be selected by the user by writing either "REMAP: BRAM" (the default) or "REMAP: QSPI" in the board configuration file. The board config file is acted on by the "Motherboard Configuration Controller", which is an entirely separate microcontroller on the dev board but outside the FPGA. The guest can also dynamically change the mapping via the SCC CFG_REG0 register. Implement this functionality for QEMU, using a machine property "remap" with valid values "BRAM" and "QSPI" to allow the user to set the initial mapping, in the same way they can on the FPGA, and wiring up the bit from the SCC register to also switch the mapping.

We know that the SD card does not have a qbus of its own, so the new device_cold_reset() function (which resets both the device and its child buses) is equivalent here to device_legacy_reset() and we can just switch to the new API.

2021-05-10xen-mapcache: avoid a race on memory map while using MAP_FIXEDIgor Druzhinin1-1/+14
When we're replacing the existing mapping there is possibility of a race on memory map with other threads doing mmap operations - the address being unmapped/re-mapped could be occupied by another thread in between. Linux mmap man page recommends keeping the existing mappings in place to reserve the place and instead utilize the fact that the next mmap operation with MAP_FIXED flag passed will implicitly destroy the existing mappings behind the chosen address. This behavior is guaranteed by POSIX / BSD and therefore is portable. Note that it wouldn't make the replacement atomic for parallel accesses to the replaced region - those might still fail with SIGBUS due to xenforeignmemory_map not being atomic. So we're still not expecting those.
