2023-11-02docs/specs/ivshmem-spec: Convert to rSTPeter Maydell
Convert docs/specs/ivshmem-spec.txt to rST format. In converting, I have dropped the sections on the device's command line interface and usage, as they are already covered by the user-facing docs in system/devices/ivshmem.rst. I have also removed the reference to Memnic, because the URL is dead and a web search suggests that whatever this was it's pretty much sunk without trace.

2023-06-28escc: emulate dip switch language layout settings on SUN keyboardHenrik Carlqvist
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout of the keyboard. Solaris makes an ioctl to query the value of the dipswitches and uses that value to select keyboard layout. Also the SUN bios like the one in the file ss5.bin uses this value to support at least some keyboard layouts. However, the OpenBIOS provided with qemu is hardcoded to always use an US keyboard layout. Before this patch, qemu allways gave dip switch value 0x21 (US keyboard), this patch uses a command line switch like "-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is used to lookup values from arguments like: -global escc.chnA-sunkbd-layout=fr -global escc.chnA-sunkbd-layout=es But the patch also accepts numeric dip switch values directly: -global escc.chnA-sunkbd-layout=0x2b -global escc.chnA-sunkbd-layout=43 Both values above are the same and select swedish keyboard as explained in table 3-15 at https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html Unless you want to do a full Solaris installation but happen to have access to a Sun bios file, the easiest way to test that the patch works is to: qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin If you already happen to have a Solaris installation in a qemu disk image file you can easily try different keyboard layouts after this patch is applied.

2023-05-19hw/cxl: Multi-Region CXL Type-3 Devices (Volatile and Persistent)Gregory Price
This commit enables each CXL Type-3 device to contain one volatile memory region and one persistent region. Two new properties have been added to cxl-type3 device initialization: [volatile-memdev] and [persistent-memdev] The existing [memdev] property has been deprecated and will default the memory region to a persistent memory region (although a user may assign the region to a ram or file backed region). It cannot be used in combination with the new [persistent-memdev] property. Partitioning volatile memory from persistent memory is not yet supported. Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

2023-05-18docs: Convert u2f.txt to rSTPeter Maydell
Convert the u2f.txt file to rST, and place it in the right place in our manual layout. The old text didn't fit very well into our manual style, so the new version ends up looking like a rewrite, although some of the original text is preserved: * the 'building' section of the old file is removed, since we generally assume that users have already built QEMU * some rather verbose text has been cut back * document the passthrough device first, on the assumption that's most likely to be of interest to users * cut back on the duplication of text between sections * format example command lines etc with rST As it's a short document it seemed simplest to do this all in one go rather than try to do a minimal syntactic conversion and then clean up the wording and layout.

In the doc sources, we have a few cross-reference targets with odd names "pcsys_005fxyz". These are the legacy of the semi-automated conversion of the old info docs to rST (the '005f' is because ASCII 0x5f is '_' and the old info link names had underscores in them). Remove the targets which nothing links to, and rename the two targets which are used to something a bit more descriptive.

2022-06-09hw/cxl: Make the CXL fixed memory window setup a machine parameter.Jonathan Cameron
Paolo Bonzini requested this change to simplify the ongoing effort to allow machine setup entirely via RPC. Includes shortening the command line form cxl-fixed-memory-window to cxl-fmw as the command lines are extremely long even with this change. The json change is needed to ensure that there is a CXLFixedMemoryWindowOptionsList even though the actual element in the json is never used. Similar to existing SgxEpcProperties. Update qemu-options.hx to reflect that this is now a -machine parameter. The bulk of -M / -machine parameters are documented under machine, so use that in preference to M.
