* nomaintainer: Fix Lesser GPL version numberChetan Pant2020-11-151-1/+1
| | | | | | | | | | | | | | | | There is no "version 2" of the "Lesser" General Public License. It is either "GPL version 2.0" or "Lesser GPL version 2.1". This patch replaces all occurrences of "Lesser GPL version 2" with "Lesser GPL version 2.1" in comment section. This patch contains all the files, whose maintainer I could not get from ‘get_maintainer.pl’ script.

* include: Make headers more self-containedMarkus Armbruster2019-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2016, we discussed[1] rules for headers, and these were generally liked: 1. Have a carefully curated header that's included everywhere first. We got that already thanks to Peter: osdep.h. 2. Headers should normally include everything they need beyond osdep.h. If exceptions are needed for some reason, they must be documented in the header. If all that's needed from a header is typedefs, put those into qemu/typedefs.h instead of including the header. 3. Cyclic inclusion is forbidden. This patch gets include/ closer to obeying 2. It's actually extracted from my "[RFC] Baby steps towards saner headers" series[2], which demonstrates a possible path towards checking 2 automatically. It passes the RFC test there.

* spapr: Use CamelCase properlyDavid Gibson2019-03-121-37/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qemu coding standard is to use CamelCase for type and structure names, and the pseries code follows that... sort of. There are quite a lot of places where we bend the rules in order to preserve the capitalization of internal acronyms like "PHB", "TCE", "DIMM" and most commonly "sPAPR". That was a bad idea - it frequently leads to names ending up with hard to read clusters of capital letters, and means they don't catch the eye as type identifiers, which is kind of the point of the CamelCase convention in the first place. In short, keeping type identifiers look like CamelCase is more important than preserving standard capitalization of internal "words". So, this patch renames a heap of spapr internal type names to a more standard CamelCase. In addition to case changes, we also make some other identifier renames: VIOsPAPR* -> SpaprVio* The reverse word ordering was only ever used to mitigate the capital cluster, so revert to the natural ordering. VIOsPAPRVTYDevice -> SpaprVioVty VIOsPAPRVLANDevice -> SpaprVioVlan Brevity, since the "Device" didn't add useful information sPAPRDRConnector -> SpaprDrc sPAPRDRConnectorClass -> SpaprDrcClass Brevity, and makes it clearer this is the same thing as a "DRC" mentioned in many other places in the code This is 100% a mechanical search-and-replace patch. It will, however, conflict with essentially any and all outstanding patches touching the spapr code. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | | | | | | | | | | | | | | The original QOMification of the spapr VIO devices in 3954d33 "spapr: convert to QEMU Object Model (v2)" moved some callbacks from the VIOsPAPRBus structure to the VIOsPAPRDeviceClass.

| | | | | | | | | | | | | | | | | The code for -machine pseries maintains a global sPAPREnvironment structure which keeps track of general state information about the guest platform. This predates the existence of the MachineState structure, but performs basically the same function. Now that we have the generic MachineState, fold sPAPREnvironment into sPAPRMachineState, the pseries specific subclass of MachineState. This is mostly a matter of search and replace, although a few places which relied on the global spapr variable are changed to find the structure via qdev_get_machine().

* spapr_vio/spapr_iommu: Move VIO bypass where it belongsAlexey Kardashevskiy2015-03-091-0/+4
| | | | | | | | | | | | | | | | | | | | Instead of tweaking a TCE table device by adding there a bypass flag, let's add an alias to RAM and IOMMU memory region, and enable/disable those according to the selected bypass mode. This way IOMMU memory region can have size of the actual window rather than ram_size which is essential for upcoming DDW support. This moves bypass logic to VIO layer and keeps @bypass flag in TCE table for migration compatibility only. This replaces spapr_tce_set_bypass() calls with explicit assignment to avoid confusion as the function could do something more that just syncing the @bypass flag. This adds a pointer to VIO device into the sPAPRTCETable struct to provide the sPAPRTCETable device a way to update bypass mode for the VIO device.
