| 2007-10-02 | Apply (with slight variants) this elimination of bzero() with M_ZERO: | Kenneth R Westerback | |
| - if ((mapstore = malloc(mapsize, M_DEVBUF, - (flags & BUS_DMA_NOWAIT) ? M_NOWAIT : M_WAITOK)) == NULL) + if ((mapstore = malloc(mapsize, M_DEVBUF, (flags & BUS_DMA_NOWAIT) ? + (M_NOWAIT | M_ZERO) : (M_WAITOK | M_ZERO))) == NULL) return (ENOMEM); - bzero(mapstore, mapsize); | |||
| 2006-06-15 | Rework the interrupt code, shaving some cycles off in the process. | Brad Smith | |
| Rather than an "iointr" routine that decomposes a vector into an IRQ, we maintain a vector table directly, hooking up each "iointr" routine at the correct vector. This also allows us to hook device interrupts up to specific vectors. From thorpej NetBSD Tested by myself and a number of end-users. | |||
| 2006-05-21 | Check for stale flags in the DMA map. | Brad Smith | |
| From thorpej NetBSD | |||
| 2006-05-21 | - _bus_dmamap_load_buffer_direct_common -> _bus_dmamap_load_buffer_direct | Brad Smith | |
| - fix _bus_dmamap_load_(uio/mbuf)_direct panic messages. - s/vm_page_alloc_memory/uvm_pglistalloc/ in panic message. From NetBSD | |||
| 2006-05-21 | Fix a couple of comments. | Brad Smith | |
| From NetBSD | |||
| 2006-05-21 | Pay attention to BUS_DMA_READ; don't need to allocate a spill | Brad Smith | |
| page if it is set. From NetBSD | |||
| 2006-05-21 | Implement dmamap_load_uio for SGMAPs. | Brad Smith | |
| From NetBSD | |||
| 2006-05-12 | Keep track of which DMA window was actually used to map the | Brad Smith | |
| request (not always the passed in DMA tag if we try direct-map and then fall back to sgmap-mapped). Use the actual window when performing dmamap_sync and dmamap_unload operations. From NetBSD ok martin@ | |||
| 2006-04-13 | Use PAGE_SIZE rather than NBPG. | Brad Smith | |
| From NetBSD ok martin@ miod@ | |||
| 2006-04-04 | clean up after Theo's "support mbuf handling in alpha sgmap dma maps" commit. | Brad Smith | |
| ok martin@ | |||
| 2006-03-27 | rev 1.30 | Brad Smith | |
| Don't increase the segment index if we skipped a zero-length mbuf. rev 1.22 Since the SGMAP buffer load subroutine doesn't need to modify the segment index, don't pass it by reference. From NetBSD ok miod@ | |||
| 2006-03-20 | factorize SGMAP-mapped DMA map creation and destroy code | Martin Reindl | |
| ok miod@, additional testing jsg@ from NetBSD | |||
| 2006-03-18 | In _bus_dmamem_alloc_range(), do not ignore the caller's ``high'' parameter. | Miod Vallat | |
| Makes isadma much happier. From NetBSD | |||
| 2006-03-13 | Protect sgmap extents with splvm(); from NetBSD. | Miod Vallat | |
| 2006-01-29 | Add a alpha_shared_intr_reset_strays() function that resets the stray | Martin Reindl | |
| interrupt counter for a given shared interrupt descriptor. When an interrupt is successfully handled, reset the strays counter, thus preventing a "slow leak" from eventually shutting off the interrupt vector. from NetBSD via KUDO Takashi | |||
| 2005-10-28 | no more Mach-macros | Martin Reindl | |
| 2004-12-25 | Use list and queue macros where applicable to make the code easier to read; | Miod Vallat | |
| no functional change. | |||
| 2004-11-09 | Do not map empty mbufs (m_len == 0) in bus_dmamap_load_mbuf() as these mappings | Claudio Jeker | |
| may disturb the dma as seen in ipw(4). Emtpy mbufs are at the beginning of the mbuf chain and are as example a "side-effect" of a previous m_adj() call. OK miod@ mickey@ jason@ markus@ | |||
| 2004-06-28 | Use new event counter API for interrupt counting on alpha. By me, with some | Aaron Campbell | |
| edits by Theo. deraadt@ ok | |||
| 2004-01-13 | support mbuf handling in alpha sgmap dma maps; from netbsd | Theo de Raadt | |
| 2003-10-18 | typos from Jared Yanovich; | Jason McIntyre | |
| 2002-10-07 | this removes the functionality of adding allocated | Michael Shalayeff | |
| pages into the queue already containing allocated pages. breaks i386:setup_buffers() because of this. | |||
| 2002-10-06 | No more need to initialize the result list before uvm_pglistalloc. | Artur Grabowski | |
| 2002-06-25 | No \n at the end of a panic() message... I thought all occurences had been | Miod Vallat | |
| squashed already. | |||
| 2002-03-20 | Since the sgmap is used in interrupts protect the extent with splvm. | Artur Grabowski | |
| nate@ ok. Should fix a bunch of random memory corruption problems on many machines. How we could live so long without it is beyond me. Now my traktor is happy. | |||
| 2002-03-14 | First round of __P removal in sys | Todd C. Miller | |
| 2001-12-08 | Sprinkle pmap_update calls where relevant and some other | Artur Grabowski | |
| misc pmap usage fixes. | |||
| 2001-11-28 | more typedef zapping vm_page_t -> struct vm_page * | Artur Grabowski | |
| 2001-11-06 | Replace inclusion of <vm/foo.h> with the correct <uvm/bar.h> when necessary. | Miod Vallat | |
| (Look ma, I might have broken the tree) | |||
| 2001-11-05 | Switch everything to the new bus_dmamap_sync API. | Artur Grabowski | |
| Most work by Wilbern Cobb <vedge@csoft.org> with some fixes from me, mickey@ and drahn@. | |||
| 2001-09-19 | merge vm/vm_kern.h into uvm/uvm_extern.h; art@ ok | Michael Shalayeff | |
| 2001-07-25 | Change the pmap_enter interface to merge access_type and the wired boolean | Artur Grabowski | |
| and arbitrary flags into one argument. One new flag is PMAP_CANFAIL that tells pmap_enter that it can fail if there are not enough resources to satisfy the request. If this flag is not passed, pmap_enter should panic as it should have done before this change (XXX - many pmaps are still not doing that). Only i386 and alpha implement CANFAIL for now. Includes uvm updates from NetBSD. | |||
| 2001-07-05 | Get rid of the wrapper macros around extent_alloc*1 | Artur Grabowski | |
| Pass the right amount of arguments and rename them back to their right names. | |||
| 2001-06-25 | cold is in systm now | Michael Shalayeff | |
| 2001-06-08 | Change the paddr_t pmap_extract(struct pmap *, vaddr_t) interface to | Artur Grabowski | |
| boolean_t pmap_extract(struct pmap *, vaddr_t, paddr_t *). Matches NetBSD. Tested by various people on various platforms. | |||
| 2001-03-21 | Move files from common to dev to be more like other archs | Artur Grabowski | |
| (and so that tab completion on "compile" works as on other archs. :)) | |||
| 2000-11-08 | tag the rest of alpha tree | Eric Jackson | |
| 2000-11-08 | Merge in big portions of the improvements NetBSD did to their alpha port. | Artur Grabowski | |
| Highlights: UVM, PMAP_NEW, bus_dma (only on some buses for now), new hardware support, possiblity for ELF, etc, etc. Too much to mention. This is still work in progress. video consoles might be broken, otherwise we have basically the same functionality as before plus more. | |||
| 1999-02-08 | In alpha_shared_intr_stray(), if intr_maxstrays is 0 just return (NetBSD) | Todd C. Miller | |
| 1999-02-08 | Because of BROKEN_PROM braindamage we need to allow an interupt | Todd C. Miller | |
| initialized (but not registered) as IST_LEVEL be assigned IST_EDGE. | |||
| 1998-12-31 | semantic change: prefer unshared intr, settle for level shared. this will ↵ | Theo de Raadt | |
| still fail in some cases | |||
| 1998-12-27 | new priority mechanism for pcmcia interrupt allocation, ie. "best effort" | Theo de Raadt | |
| for machines low on interrupts. work by fgsch, and myself | |||
| 1998-06-29 | isa_intr_check(), alpha style. | Jason Downs | |
| 1997-11-10 | $OpenBSD$ | Niklas Hallqvist | |
| 1997-11-06 | We need an MI vga driver. The alpha one was most MI. Not entirely yet though. | Niklas Hallqvist | |
| Some files were move behind CVS back. | |||
| 1997-08-25 | better mmap support, what fun | Theo de Raadt | |
| 1997-08-22 | wscons -> vga_xxx -> vga mmap() support. first cut | Theo de Raadt | |
| 1997-07-31 | text video attributes, tested only on vga, send me E-mail if it breaks ↵ | kstailey | |
| something, thx. | |||
| 1997-07-31 | bus_space_copy_2() is now overlap safe | kstailey | |
| 1997-07-10 | fix vga_copycols(9) | kstailey | |
