Adjust path for mdoc.local

(martin)

Note added for a strange value of residual counts in successful read/write.
Seems like a H/W bug. The best thing we can do would be to leave the code as is.

No binary changes.

(rin)

clean up a little

(maxv)

No, this cannot be bar 0 -- it is bar 2 or bar 3, as shown above.

(riastradh)

Let's try not to use uninitialized memory as a bus size, shall we?

From rjs@.

(riastradh)

Add NetBSD 8.0

(martin)

Revert previous, this is the wrong place

(martin)

Return timeout left, not error, if fence is already signaled.

fence_add_callback returns -ENOENT if fence is already signaled;
radeon_fence_default_wait is supposed to wait until fence is
signaled; this means its job is done.

Should fix spurious ENOENT in DRM_IOCTL_RADEON_GEM_WAIT_IDLE (or
_IOW('d',0x64,0x8) for you ktracers out there).

(riastradh)

Welcome to NetBSD 7.2!

(martin)

Add a bunch of NetBSD versions

(martin)

Fix swapped version numbers, remove huge and useless "We are" section.
Bump date.

(martin)

Whitespace

(skrll)

Initialize transition slew rate if specified in the DT

(jmcneill)

Make sure getnewbuf() runs bawrite() inside fstrans.
Use fstrans_start_nowait() to skip buffers that would block.

(hannken)

Add two new states FSS_CREATING and FSS_DESTROYING and use them
while creating or destroying a snapshot.

Remove now unneeded sc_lock that made fss_ioctl mutually exclusive.

Fss_ioctl no longer blocks forever because a snapshot gets
created or destroyed.

Serialize snapshot creation and make it interruptible.

(hannken)

Convert flags FSS_ACTIVE and FSS_ERROR into new member sc_state
with states FSS_IDLE, FSS_ACTIVE and FSS_ERROR.

No functional change intended.

(hannken)

Fix a bug that media change may fail. I noticed that ifconfig ixgN media XXX
took a 10 or more seconds on a Denverton machie. I occurred by trying take a
lock and timed out. The reason was that ixgbe_media_change() didn't take
CORE_LOCK. Do it.

This problem was from FreeBSD's pre-iflib ixgbe (I don't know whether this
problem really occurs on FreeBSD or not). Post-iflib ixgbe has no problem
because iflib_media_change() takes a lock.

(riastradh)

Rework PCI and AGP conditionalization.

- Push drm_pci_set_unique into driver callback.
- Eliminate drm_pci_set_unique_hook.
- Gather all drm_agp_* functions into struct drm_agp_hooks.
- Replace the nonsensical old atomic garbage by serious locking.
- Make drm_agpsupport.c its own module.
- Eliminate NDRMKMS_PCI.
- Use NAGP from "agp.h" only in drm_module.c for horrible hack.
  => See comment in file for rationale.
- Always define CONFIG_PCI=1 and CONFIG_AGP=1.
- Always go through the drm_agp_* function hooks.
- Ifdef out nouveau agp stuff that doesn't go through drm_agp_*
  for reasons that I'm too frustrated to figure out tonight.
- pci_iomap no longer automagically does agp_i810_borrow.
  => Use drm_agp_borrow instead.

(riastradh)

Move decl of drm_guarantee_initialized to drmP.h.

(riastradh)

Return the node we found.  From tnn@.

(riastradh)

Convert to uintmax_t if we're going to use %jx.

need to add VM_PROT_READ when pmap_kenter_pa(va, pa, VM_PROT_WRITE, 0) or pmap_kenter_pa(va, pa, VM_PROT_EXECUTE, 0).

(riastradh)

Check for DMA-safe addresses before allowing DRM prime import.

(riastradh)

Implement BUS_DMA_TO_PHYS/PHYS_TO_BUS_DMA on arm respecting ranges.

(riastradh)

Tread carefully around DMA subregions.

Not all platforms support it.

- If we want to limit to 32-bit DMA, just use a known 32-bit DMA tag.
- If we want to limit to >32-bit DMA, but the host only has a known
  32-bit DMA tag, then just use that anyway.
- If we want to limit to >32-bit DMA, but the host doesn't support
  bus_dmatag_subregion, then just use the 32-bit DMA tag anyway.

Gives powerpc, sparc a chance of working.

(riastradh)

Update tegra drm and nouveau to compile with new drmkms.

Compile-tested only.

(riastradh)

Make drmkms build without drmkms_pci.

(riastradh)

Make this compile.

(riastradh)

Unhook upstream drm_pci.c, apparently overridden by files.drmkms_pci.

(riastradh)

At chuq's suggestion, use paddr_t rather than struct vm_page *.

Doesn't make much of a substantive difference.

(riastradh)

Draft sparc cache flushing.

(riastradh)

sparc seems to treat bus/phys addrs in bus dmamem the same.

This is just about bus dmamem -- not about bus dmamap, which rightly
uses an iommu to remap things and which we don't interfere with.

(riastradh)

Ifdef out label used only by !__HAVE_MM_MD_DIRECT_MAPPED_PHYS.

(riastradh)

Work around broken null bus_dmatag_destroy expansion.

(riastradh)

(riastradh)

Let's try not to step on each others' toes, shall we?

(riastradh)

Clarify what bus_dmat and dmat are.

(riastradh)

Use dmat, not bus_dmat, to respect drm_limit_dma_space.

(riastradh)

Eliminate now-unused bus_dmamap_load_pgarray.

(riastradh)

drm_gem_cma_create_internal can fail.

(riastradh)

Include amdgpu_prime.c now that it will compile.

(riastradh)

Rework drm prime guts.

- Our faux struct sg_table is now just an array of _pages_, not of
  bus dma segments.

- We handle bus dma segments only in the presence of an adult bus dma
  tag.

- All bus dma hacks are once again confined to bus_dma_hacks.h, and
  more neatly organized:
  . bus_dmamem_export_pages translates bus dma segs to vm_page array
  . bus_dmamem_import_pages translates vm_page array to bus dma segs

(riastradh)

Not drm prime; just unused.

(riastradh)

Implement remainder of drm_gem_cma_helper API.

(riastradh)

Fill out drm_prime_* API a little more for NetBSD.

Add comment explaining our use of struct sg_table.

(riastradh)

Workqueue lock must be at IPL_VM for use in interrupts, duh.

(riastradh)

sdt probe naming style.

(riastradh)

Simplify.  Destroy the mutex too.

(riastradh)

Factor mfence out.  Simplify a little.

(riastradh)

Return the fd we just allocated.

(riastradh)

Need sync after a series of dcbf's on powerpc.

(riastradh)

Forgot to commit drm_trace_netbsd.h.  Too late to force an update...

(riastradh)

Draft support for drm prime.

(riastradh)

Remove references to -c flag which was never included.

(sevan)

Work around `kmap' namespace clash another way.

(riastradh)

Omit vestigial diff from radeon_mode.h.

(riastradh)

Convert to long for format expedience.

(riastradh)

Try agp_i810_borrow only if CONFIG_AGP is enabled.

(riastradh)

opt_mtrr.h is x86-only.

(riastradh)

Use PHYS_TO_BUS_MEM in generic bus_dmamap_load_pglist code.

For arm and x86, this is a noop.  For powerpc, it is defined by some
relevant header file.

(riastradh)

Implement drm_md_clflush_* for powerpc with dcbf.

(riastradh)

Use Linux atomic64 for ww mutex class.

This way we can take advantage of the hash-locked atomic64 on
platforms that lack native atomic_inc_64_nv.

(riastradh)

Implement atomic64_add_return and atomic64_inc_return.

(riastradh)

Sort.

(riastradh)

Fix argument types of atomic64_add/sub to be sensible.

Technically Linux does use long long rather than int64_t, but that's
silly.

(riastradh)

Implement ATOMIC64_INIT.

(riastradh)

Need <uvm/uvm.h> for struct uvm_object.

(riastradh)

Sprinkle AGP conditionals where needed.

(riastradh)

Work around a namespacing clash between dtrace and linux symbol.

(riastradh)

Use dtrace probes to implement i915_trace.h.

(riastradh)

Hash-locked atomic64 to give ports like powerpc32 a chance at radeon.

(riastradh)

Delete spurious file accidentally committed.

(riastradh)

dtrace sdt probes for linux rcu.

(riastradh)

Don't skimp on the last batch of work when worker is dying.

This is capitalism.  We can't afford to waste time the worker could
spend on labour even if we work 'em to death!

(riastradh)

Work around broken empty expansion of SDT_PROBE* if !KDTRACE_HOOKS.

(riastradh)

sdt dtrace probes for linux kmap.

(riastradh)

sdt dtrace probes for linux idr.

(riastradh)

Sprinkle dtrace probes all over the Linux workqueue stuff.

(riastradh)

Fix post-cancellation case of queue_delayed_work.

Request the callout queue immediately, as if it hadn't been cancelled
at all, rather than reschedule for the next tick.

(riastradh)

Rework Linux workqueue synchronization yet again.

- Use a low bit in the pointer to the queue, rather than whether the
  pointer is null or not, to determine whether the work item is
  queued/scheduled.

- _Preserve_ the pointer to the queue after we release the work.

- Release the work _before_ executing the function, not after.

This simplifies some things: we no longer have to distinguish whether
the work is queued or running in the functions where we are trying to
modify it.  The pointer has to be preserved even after the work is
released so that we can flush the workqueue after the work has been
released.

(riastradh)

Fix flush_delayed_work semantics: run it now if it was scheduled.

(riastradh)

Reorder fields to get better space savings than bit fields.

(riastradh)

Document workqueue semantics as I understand it.

(riastradh)

Avoid the prospect of callout calls piling up.

Don't ever callout_schedule the callout while an existing call may be
in progress.

Echo some cases from cancel_delayed_work in flush_delayed_work.

(riastradh)

Don't let more than one thread claim credit for cancellation.

(riastradh)

Factor out waiting for current work.

(riastradh)

Merge two similar branches.

(riastradh)

Deduplicate callout destruction.

(riastradh)

Deduplicate callout initialization.

(riastradh)

Handle a bazillion additional cases I hadn't considered.

There's a lot of duplication here.  To be deduplicated in a
subsequent commit.

(riastradh)

Fix semantics of flush_work and flush_delayed_work.

- Change return type to void.
  => Upstream it is bool, but exactly one of hundreds of callers
    actually use it, and I don't think the semantics is clear.

- Make sure to wait for whichever of the current work _and_ the next
  batch queued is currently there in the workqueue.

- Don't retry a cancelled callout.  Cancellation in the state
  DELAYED_WORK_CANCELLED is guaranteed.

(riastradh)

Reverse the sense of some branches for simplicity.

(riastradh)

Fix bugs in workqueue destruction.

(riastradh)

Fully initialize workqueue struct. Zalloc for paranoia.

(riastradh)

No need to retry in cancel_delayed_work_sync after all.

(riastradh)

Deduplicate post-cancellation logic.

(riastradh)

Don't touch a work after it is released.

(riastradh)

Non-waiting cancellation may need to release work too.

(riastradh)

After cancel and callout_halt, may need to reload workqueue.

(riastradh)

Don't wait forever to flush if the worker thread has no work.

(riastradh)

Sprinkle some assertions.

(riastradh)

Exercise greater care in acquiring and releasing work.

(riastradh)

Check ifp->if_capenable, not ifp->if_capabilities, when enable some features.
Not a real problem since ifp->if_capabilities = 0 at the moment.

(rin)

Add missing break.

(riastradh)

Add missing namespace for flush_scheduled_work.

(riastradh)

Add KASSERT about state after callout fires.
