* 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/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hw: clean up hw/hw.h includesPaolo Bonzini2016-05-191-4/+0Star
| | | | | | | | | | | | | Include qom/object.h and exec/memory.h instead of exec/ioport.h; exec/ioport.h was almost everywhere required only for those two includes, not for the content of the header itself. Remove block/aio.h, everybody is already including it through another path. With this change, include/hw/hw.h is freed from qemu-common.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* hw: remove pio_addr_tPaolo Bonzini2016-05-191-9/+6Star
| | | | | | | | | | | | | | | pio_addr_t is almost unused, because these days I/O ports are simply accessed through the address space. cpu_{in,out}[bwl] themselves are almost unused; monitor.c and xen-hvm.c could use address_space_read/write directly, since they have an integer size at hand. This leaves qtest as the only user of those functions. On the other hand even portio_* functions use this type; the only interesting use of pio_addr_t thus is include/hw/sysbus.h. I guess I could move it there, but I don't see much benefit in that either. Using uint32_t is enough and avoids the need to include ioport.h everywhere.

* portio: Allow to mark portio lists as coalesced MMIO flushingJan Kiszka2013-10-171-0/+2
| | | | | | | | This will enable us to remove all remaining explicit calls of qemu_flush_coalesced_mmio_buffer in IO handlers. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* memory: Provide separate handling of unassigned io ports accessesJan Kiszka2013-09-051-0/+4
| | | | | | | | | | Accesses to unassigned io ports shall return -1 on read and be ignored on write. Ensure these properties via dedicated ops, decoupling us from the memory core's handling of unassigned accesses.

* ioport: Switch dispatching to memory core layerJan Kiszka2013-07-041-1/+0Star
| | | | | | | | | | | | | | | | | | | | | The current ioport dispatcher is a complex beast, mostly due to the need to deal with old portio interface users. But we can overcome it without converting all portio users by embedding the required base address of a MemoryRegionPortio access into that data structure. That removes the need to have the additional MemoryRegionIORange structure in the loop on every access. To handle old portio memory ops, we simply install dispatching handlers for portio memory regions when registering them with the memory core. This removes the need for the old_portio field. We can drop the additional aliasing of ioport regions and also the special address space listener. cpu_in and cpu_out now simply call address_space_read/write. And we can concentrate portio handling in a single source file. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* isa: implement isa_is_ioport_assigned via memory_region_findJan Kiszka2013-07-041-1/+0Star
| | | | | | | | | Open-code isa_is_ioport_assigned via a memory region lookup. As all IO ports are now directly or indirectly registered via the memory API, this becomes possible and will finally allow us to drop the ioport tables.
