Lotsa kasserts about referencedness of frences.

(riastradh)

Acquire references in add_shared/excl.

(riastradh)

Call linux_pci_dev_init/destroy in viadrmums(4) too.

(riastradh)

Let upstream code attempt match for nouveau.

(riastradh)

Call linux_pci_dev_destroy on detach.

(riastradh)

Implement linux_pci_dev_destroy.

(riastradh)

Pass the parent explicitly to linux_pci_dev_init.

This will allow us to use it in match routines.

(riastradh)

Move linux_pci_dev_init into callers of drm_pci_attach.

The order in nouveau has to be

- linux_pci_dev_init
- nvkm_device_pci_new
- rest of drm_pci_attach

(riastradh)

Locks are not like negatives: doubles don't cancel out.

(riastradh)

Disable broken workqueue_whoami garbage.

(riastradh)

Update amdgpu2netbsd script.

(riastradh)

Rename amdgpu files to avoid clashes with radeon.

(riastradh)

Don't hork on DEBUG builds.

(riastradh)

Note radeon/amdgpu file collisions TODO in README.

(riastradh)

Tired of fine-grained commits.  Have an amdgpu(4).

(riastradh)

const const const const const

(riastradh)

Convert amdgpu scheduler to drm waitqueues and NetBSD kthreads.

(riastradh)

Don't abuse struct fence internals for irreverent dolphins.

(riastradh)

Delete upstream trace point header files that get in the way.

(riastradh)

Add some amdgpu goo.

(riastradh)

Empty stub <linux/irq.h>.

Not sure why upstream uses it -- the file in Linux exhorts against
its usage in any MI code.

(riastradh)

Draft reservation_object_get_fences_rcu.

(riastradh)

Add fence_is_later and fence_wait_any_timeout.

(riastradh)

Fix prototype of function in comment.

(riastradh)

Rewrite <linux/kfifo.h>.

pcq isn't flexible enough for its needs now.  Just use a spinlocked
circular buffer.

(riastradh)

Add atomic_long.

(riastradh)

Note need_mmap_used is __diagused, not __unused.

(riastradh)

Define nsecs_to_jiffies.

(riastradh)

Need <sys/kernel.h> for boottime.

(riastradh)

Teach drm_sysctl about uint, kludgily.

(riastradh)

Add a copy of __user (empty) to <linux/types.h> for expedience.

(riastradh)

Define list_splice_init.

(riastradh)

Make sure to call pslist_entry_init.

(riastradh)

Fence release callback may be absent; default to fence_free.

(riastradh)

Fix ordering of bus_dmamap_sync.

The ordering is:

...
- driver writes to kernel pointer
- sync
- driver triggers device use of newly written data (*)
- sync
- driver writes to kernel pointer
- sync
...

The operation (*) is a DMA write.  Hence the syncs should be:

...
- driver writes to kernel pointer
- bus_dmamap_sync(BUS_DMASYNC_PREWRITE)
- driver triggers device use of newly written data
- bus_dmamap_sync(BUS_DMASYNC_POSTWRITE)
- bus_dmamap_sync(BUS_DMASYNC_PREWRITE)
- driver writes to kernel pointer
- bus_dmamap_sync(BUS_DMASYNC_POSTWRITE)
- bus_dmamap_sync(BUS_DMASYNC_PREWRITE)
...

(riastradh)

GART might not be mapped with bus_dma.

Still need membar and tlb flush in that case.

(riastradh)

(riastradh)

Apparently one can reserve_shared only once in a row.  Simplify.

(riastradh)

Make drmkms_pci.kmod build again.

(riastradh)

Upstream nixed __OS_HAS_AGP; use CONFIG_AGP instead.

(riastradh)

Reverse backwards namespacing.

(riastradh)

Add missing namespacing.

(riastradh)

Newline-terminate error message.

(riastradh)

Move hweight8 next to its cousins.

(riastradh)

Move CPPFLAGS to top, CWARNFLAGS below.

(riastradh)

Omit commented warn flag, evidently needless.

(riastradh)

Make drmkms.kmod build again on amd64.

(riastradh)

Define CONFIG_DRM_FBDEV_EMULATION=1 in generic drmkms code.

This was accidentally pulled in by i915drmkms, but we need it
generically or else we need to patch upstream differently.

(riastradh)

Sort.  Put CWARNFLAGS next to source lists.

(riastradh)

Guard #include "pci.h" with _KERNEL_OPT.

(riastradh)

Add some components to drmkms_linux.kmod.

(riastradh)

Sort.

(riastradh)

Sort.

(riastradh)

Nix extraneous whitespace.

(riastradh)

Implement kvfree by free(9); assume kmalloc/vmalloc use malloc(9).

(riastradh)

Insert membars needed for non-x86.

XXX We should really define membar_enter_postatomic and
membar_exit_preatomic to avoid relying on not typoing
__HAVE_ATOMIC_AS_MEMBAR.

(riastradh)

With <asm/cpufeature.h>, we can now use cpu_has_pat.

(riastradh)

Define cpu_has_pat for x86.

(riastradh)

Make this a proper boolean.  Skip ISSET.  Add some spacing.

(riastradh)

Rename nouveau_devices_init/fini -> nvkm_devices_init/fini.

Matches newer upstream naming conventions better.

(riastradh)

Fold local intel_uncore_destroy into upstream intel_uncore_fini.

(riastradh)

Move hint setting nearer to uvm_map for clarity.  CTASSERT page size.

Elsewhere this code says 4096, rather than PAGE_SIZE.  PAGE_SIZE is
the smallest unit that uvm_map accepts, so it had better match.

(riastradh)

Initialize kva hint for uvm_map to avoid using uninitialized memory.

(riastradh)

Update usage() to include documented flags

(sevan)

Remove temporary diagnostic now that I know I forgot uio_offset.

(riastradh)

Put file, line, func in DRM_ERROR messages.

(riastradh)

Don't forget to initialize uio_offset.

(riastradh)

Turn on driver debug messages for now

Author: coypoop <coypu@sdf.org>
Committer: Taylor R Campbell <riastradh@NetBSD.org>

(riastradh)

Transfer from the correct offset.

(riastradh)

Temporary diagnostic kludge: confirm the ubc_uiomove worked as expected.

(riastradh)

Guess what uvm criterion means we should discard backing pages.

(riastradh)

Stub SYS_RESTART for reboot notifications so we can remove panic("XXX").

(riastradh)

Attempt to match Linux semantics for membars implied by atomics.

This is kind of moot at the moment because we're mostly x86-only for
drmkms, but this might help in the future if we ever went beyond x86.

(riastradh)

Nix memory barriers that were nixed upstream.  Add smp_mb__after_atomic.

(riastradh)

Fix return types of test_and_{set,clear,change}_bit.

(riastradh)

Don't forget to set .uio_offset and to call UIO_SETUP_SYSSPACE.

(riastradh)

i915 needs firmware now too, so defer to mountroot.

(riastradh)

Don't forget to call kthread_exit.

(riastradh)

Free the bus crap.

(riastradh)

For the kludges we don't have or need a device (parent) pointer.

(riastradh)

Nix vestigial temporary.

(riastradh)

Omit vestigial cruft.

(riastradh)

Try to avoid uninitialized garbage that gcc helpfully ignores.

(riastradh)

Conditional here shouldn't be necessary now.

(riastradh)

Copy va_list before using it twice.

(riastradh)

Can't and needn't xcall while cold.

(riastradh)

Fix vestigial call to drm_fb_helper_set_config.

(riastradh)

Use atomics to manage fence->flags.

Outside users use this field too, and expect it to be managed with
atomics.

(riastradh)

Update comment to reflect reality.

(riastradh)

Remove temporary drm_fb_helper_set_config stub from old code.

(riastradh)

Try not to ask rbtree to overwrite random fields with garbage.

Wait for the read to be valid!

(riastradh)

Stub out intel_dsi_init.

(riastradh)

Fix fence API usage: lock is _not_ held here, so acquire it.

(riastradh)

Draft implementation of the Linux reservation and fence APIs.

(riastradh)

Implement some of the Linux RCU API.

(riastradh)

Add missing -width; remove unnecessary .Pp.

(wiz)

Improve the "Map" section.

Convert nouveau clk to condition variables.

Not totally sure that the activity in nvkm_pstate_work that must
