Warner Losh	1d386b48a5	Remove $FreeBSD$: one-line .c pattern ... Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/	2023-08-16 11:54:42 -06:00
Marcel Moolenaar	015b858345	Rename busdma_sync() to busdma_sync_range() and rename the ... base and size parameters to ofs and len (resp). Add a new busdma_sync() that makes the entire MD coherent.	2015-08-02 01:09:30 +00:00
Marcel Moolenaar	71d80fbaf3	Change the dev argument from a full path to just the device ... identification (e.g. isa:0x3f0 or pci0:2:1:0). In libbus, the device is turned into a path name. For bus_space_map(), the resource is now specified in a second argument. Before: bus.map('/dev/proto/pci0:2:1:0/pcicfg') busdma.tag_create('/dev/proto/pci0:2:1:0/busdma', ...) Now: bus.map('pci0:2:1:0', 'pcicfg') busdma.tag_create('pci0:2:1:0', ...)	2015-07-26 21:37:31 +00:00
Marcel Moolenaar	9af0c69a15	Remove debugging output. We should have tracing instead.	2015-07-26 16:40:51 +00:00
Marcel Moolenaar	4af242aad1	Implement busdma_md_unload() and busdma_sync(). ... While here: 1. have the Python bindings contain constants for the space identifiers and the sync operation. 2. change the segment iterators to return None when done, not ENXIO.	2015-07-03 05:47:56 +00:00
Marcel Moolenaar	22900685fd	Add busdma_md_create, busdma_md_destroy and busdma_md_load.	2015-07-03 02:06:47 +00:00
Marcel Moolenaar	d11f2a4c8d	Free the segment objects properly.	2015-06-12 14:53:56 +00:00
Marcel Moolenaar	cc6064789f	Add accessor functions for iterating over segments. A segment ... can be in bus address space, physical memory space or virtual memory space.	2015-06-11 03:02:40 +00:00
Marcel Moolenaar	cbb052dd3e	Map the allocated DMA memory into the address space.	2015-06-08 22:01:34 +00:00
Marcel Moolenaar	6f769b730c	Add busdma_mem_alloc & busdma_mem_free.	2015-06-08 03:23:20 +00:00
Marcel Moolenaar	9c2cdb1a7e	Add DMA tag management to the C library and Python binding.	2015-06-06 16:14:03 +00:00
