2024-04-09Revert "hw/virtio: Add support for VDPA network simulation devices"Michael S. Tsirkin
This reverts commit cd341fd1ffded978b2aa0b5309b00be7c42e347c. The patch adds non-upstream code in include/standard-headers/linux/virtio_pci.h which would make maintainance harder. Revert for now.

2024-02-14hw/cxl: Standardize all references on CXL r3.1 and minor updatesJonathan Cameron
Previously not all references mentioned any spec version at all. Given r3.1 is the current specification available for evaluation at www.computeexpresslink.org update references to refer to that. Hopefully this won't become a never ending job. A few structure definitions have been updated to add new fields. Defaults of 0 and read only are valid choices for these new DVSEC registers so go with that for now. There are additional error codes and some of the 'questions' in the comments are resolved now. Update documentation reference to point to the CXL r3.1 specification with naming closer to what is on the cover. For cases where there are structure version numbers, add defines so they can be found next to the register definitions.

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.

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. Update cxl-test and bios-tables-test to reflect new parameters.

2022-05-13docs/cxl: Add initial Compute eXpress Link (CXL) documentation.Jonathan Cameron
Provide an introduction to the main components of a CXL system, with detailed explanation of memory interleaving, example command lines and kernel configuration. This was a challenging document to write due to the need to extract only that subset of CXL information which is relevant to either users of QEMU emulation of CXL or to those interested in the implementation. Much of CXL is concerned with specific elements of the protocol, management of memory pooling etc which is simply not relevant to what is currently planned for CXL emulation in QEMU.
