(riastradh)

Half-arsed conversion of i915 pending flip queue to drm_waitqueues.

(riastradh)

Ifdef out Linux framebuffer stuff in i915 intel_display.c.

(riastradh)

Add kludgey dev field to struct i2c_adapter for intel_dp.

(riastradh)

Add stubs for flush_workqueue and flush_scheduled_work that warn.

Add EREMOTEIO as an alias for EIO to <linux/err.h>.

(riastradh)

Add min_t and DIV_ROUND_UP to <linux/kernel.h>.

(riastradh)

Add mdelay to <linux/delay.h>.

(riastradh)

Add several operations to <linux/atomic.h>.

atomic_add_unless
atomic_clear_mask
atomic_inc_not_zero
atomic_set_mask
atomic_sub

(riastradh)

Define WARN_ONCE in Linux <asm/bug.h>.

(riastradh)

Ifdef out dmi hacks in i915 intel_display.c.

(riastradh)

Make intel_prepare_ddi_buffers static in intel_ddi.c.

(riastradh)

Ifdef out dmi hack in intel_crt.c.

(riastradh)

Restore use of print_hex_dump in drm_edid.c.

(riastradh)

Fix #endif include-protection comment in <linux/printk.h>.

(riastradh)

Add hex dumping utilities to <linux/printk.h>.

(riastradh)

Hook drm_dp_helper.c back into drm2.kmod, now that we have i2c shims.

(riastradh)

drm_dp_helper.c needs <linux/export.h>.

(riastradh)

Use __pci_rom_iomem marker in intel_parse_bios.

(riastradh)

Add kludgey implementation of pci_map_rom.

(riastradh)

Disable dmi hacks in i915/intel_bios.c for now.

(riastradh)

Fix const in get_lvds_dvo_timing.

(riastradh)

<linux/delay.h> needs <sys/kernel.h> for hz (in mstohz).

(riastradh)

Implement Linux alloc_page/__free_page and kmap_atomic/kunmap_atomic.

(riastradh)

Move GFP (`get free page') constants to <linux/gfp.h>.

Declare alloc_page and __free_page there too, to be implemented soon.

(riastradh)

Add struct page to <linux/mm_types.h> as a struct vm_page wrapper.

(riastradh)

Fill struct shrink_control with nr_to_scan in <linux/shrinker.h>.

i915_gem wants to use it.

(riastradh)

Fix pointer nature of INIT_COMPLETION in <linux/completion.h>.

(riastradh)

Add list_del_init to <linux/list.h>.

(riastradh)

Add a bunch of i915 trace stubs to i915_trace.h.

(riastradh)

Replace ALIGN by round_up in i915_gem.c.

ALIGN means something else in NetBSD.

(riastradh)

Ifdef out drm prime stuff from i915_drv.c.

(riastradh)

<linux/string.h> needs <sys/null.h> for NULL.

(riastradh)

Fix up some bit-hacking and pointer-futzing in <linux/kernel.h>.

- Avoid C arithmetic pitfalls and multiple evaluatoin in round_up.
- Add round_down.
- Explain why upper_32_bits and lower_32_bits exist.
- Explain what container_of does.

(riastradh)

Use kmem for drm_sg_mem records in local drm_scatter.c.

(riastradh)

Hack up ACPI memory-mapped I/O for intel_opregion.c.

This is absolutely the wrong thing, but

. it will probably work for now,

. it is much more expedient than rewriting all this code with NetBSD
bus space access or drm maps, and

. the problem remains marked so that it is easily greppable.

(riastradh)

Add local i915_pci.c for PCI driver attachment goop.

(riastradh)

Expose the i915 struct drm_driver and PCI id list from i915_drv.c.

(riastradh)

Ifdef out Linux-specific stuff in i915_drv.c.

PCI driver attachment goop, VM hooks, power management operations,
file operations.  We'll do this all in another file for NetBSD.

Ifdef out the now-unused i915_modeset parameter for now, too.

(riastradh)

Prefix `error: '/`warning: ' to Linux dev_err/dev_warn output.

(riastradh)

Print a warning if the drm(4) unit number is >=64.

(riastradh)

Add trace_i915_gem_object_create to i915_trace.h.

(riastradh)

Use an intermediate call in WARN* to avoid GCC compiler warnings.

For some reason this shuts it up about statements without effect.

(riastradh)

Fix Linux mutex_lock_interruptible to return an error.

(riastradh)

Use %d, not %s, for the error number in i915_module.c.

(riastradh)

Hook i915_module.c into the i915drm2 module build.

(riastradh)

Restore usage of pci_get_bus_and_slot in i915_get_bridge_dev.

(riastradh)

Kludge up Linux PCI device shims.

. New drm_pci_attach/drm_pci_detach simplify initialization of
autoconf-derived struct pci_dev.

. New linux_pci_dev_init initializes struct pci_dev so that there's
one place where all its fields are listed.  The kludge parameter is,
well, kludgey.  Sorry.

. Replace pci_kludgey_find_dev by pci_get_bus_and_slot with the same
interface as Linux's, but some kasserts requiring it to look for the
one bus/device/function tuple that i915drm is interested in.

. Add pci_get_class which does similarly, for intel_detect_pch.

Later pci_get_bus_and_slot and pci_get_class should be fixed once we
can pass a cookie through PCI bus enumeration and pci_find_device.

(riastradh)

Constify string irqname in drm_irq_install.

(riastradh)

Constify name, desc, and date strings in struct drm_driver.

(riastradh)

Add trace_i915_reg_rw to i915_trace.h.

(riastradh)

Add drm_config_found for foodrm_attach to call to attach drm(4).

(riastradh)

Reject drm ioctls through control minors unless explicitly allowed.

(riastradh)

Rework drm minor allocation in local drm_drv.c.

Need multiple different minors, of different types, for each drm
device.

(riastradh)

Compare dev->agp and dev->sg against NULL in drm_fops.c.

(riastradh)

Don't mess with guts of struct completion in i915_gem.c.

(riastradh)

i915_gem.c needs <asm/param.h> for HZ.

(riastradh)

Use time_t, not unsigned long, for i915 last_gpu_reset.

(riastradh)

Omit more stuff that pmf does for us in i915_drv.c.

(riastradh)

Omit Linux framebuffer stuff from i915_drv.c.

(riastradh)

Use pci_dev_dev to get at a pci_dev's device_t in i915_drm_freeze.

(riastradh)

Omit needless pci_save_state from i915_drm_freeze, courtesy pmf.

(riastradh)

Add pci_{read,write}_config_byte to <linux/pci.h>.

(riastradh)

Need more zeros for struct pci_device_id initializer in i915_drv.c.

(riastradh)

i915_drv.c needs <linux/moduleparam.h> and <linux/time.h>.

(riastradh)

Kludgily work around flush_workqueue in i915_driver_unload.

(riastradh)

Use drm_io_mapping_create_wc in i915_driver_load.

(riastradh)

Add <linux/time.h> with get_seconds, hacked to return time_t.

(riastradh)

Fix struct pci_dev::dev in <linux/pci.h>.

Linux code expects it to be a struct device and takes its address,
but we can't arrange for the actual struct device to go there.

(riastradh)

Add drm_io_mapping_create_wc to drmP.h.

Linux's io_mapping_create_wc just takes a bus address and a size, but
we need to pass along extra information, namely the bus space tag,
which we shall pass via a struct drm_device.

(riastradh)

Fill <linux/io-mapping.h> with an io_mapping abstraction.

Mapped to bus space reservations.  This might not be appropriate --
non-x86 platforms don't have them yet, and I'm not 100% confident
that Linux uses io_mappings for regions exclusively like bus space
reservations will require, but if that requirement is violated then
at least it will fail noisily, whether because of a bug or because
Linux io_mappings work differently.

(riastradh)

Add dev_err to <linux/device.h> as another device_printf alias.

(riastradh)

Comment that CPPFLAGS+=-DFOO in drm2/Makefile.inc is wrong.

Fixing this requires some thought, which would be inexpedient at the
moment.

(riastradh)

Define CONFIG_X86 in the drm2 modules on x86.

(riastradh)

Fill in <linux/pci.h> a bit.

(riastradh)

Work around rb_tree_iterate API botch in linux_idr.c.

(riastradh)

Tweak idr_pre_get.

. No need to test kmem_alloc(n, KM_SLEEP) for NULL.
. Avoid kmem_free with lock held, out of paranoia.

(riastradh)

Rework <linux/completion.h> to match Linux semantics.

(riastradh)

Restore struct intel_gmbus::bit_algo now that we have Linux i2c shims.

(riastradh)

Add DRM_READ64 and DRM_WRITE64 to drmP.h.

(riastradh)

Add currently empty i915_trace.h to appease i915 code.

(riastradh)

Add drm2edid to the commented list of what i915drm2 should depend on.

(riastradh)

Make drm2 module depend on iic, and comment on wrong dependencies.

(riastradh)

Remove comment about cargo-cult provenance of drm_memory.c.

Only drm_ioremap was cargo-culted from the old drm's drm_memory.c,
and that's a bit of a strong word for it by now.

(riastradh)

Use cpp to prefix linux_ to all the idr names.

Now all global symbols drm2.kmod defines begin with linux_ or drm_,
making it easier to check whether I've missed anything by running

  nm --undefined-only drm2.kmod | awk '$3 ~ /^(drm|linux)_/'

(riastradh)

`#define list_sort linux_list_sort' so `nm | grep linux' finds it.

(riastradh)

Restore ddc probing in drm_edid.c now that we have Linux i2c shims.

Also include <linux/string.h> for memchr_inv.

(riastradh)

Add memchr_inv to <linux/string.h>.

(riastradh)

Replace dma_set_coherent_mask by drm_limit_dma_space in i915_dma.c.

(riastradh)

Add drm_limit_dma_space to limit the memory available for DMA.

Designed as a compatibility stub to replace dma_set_coherent_mask in
Linux.  Not exactly the same, but probably close enough for all uses
of dma_set_coherent_mask in Linux.

(riastradh)

Add Linux <acpi/button.h> and <acpi/video.h>, empty for now.

(riastradh)

Add partial Linux i2c shim.

Just the parts we need for i915drm for now -- well, most of them;
more to come later.

(riastradh)

intel_drv.h needs <asm/processor.h> for cpu_relax.

(riastradh)

drm_bufs.c doesn't need <asm/mtrr.h> after all (drmP.h gets it).

(riastradh)

Define CONFIG_MTRR in drm2 modules on x86.

XXX We really need a better place for this stuff...

(riastradh)

Add 16-bit (RMW) pci_{read,write}_config_word to <linux/pci.h>.

(riastradh)

Add Linux <asm/processor.h> with cpu_relax() (= DELAY(1), for now).

(riastradh)

Ifdef out some Linux framebuffer stuff in i915.

(riastradh)

Use `static inline', not `extern inline', in i915_drv.h.

(riastradh)

Ifdef out i915_gem_object_get_page and i915_gem_fault in i915_drv.h.

Will restore when we have GEM VM stuff worked out.

(riastradh)

Unhook i915_debugfs.c and i915_sysfs.c from the build.

(riastradh)

i915_gem_context.c needs <linux/err.h>.

(riastradh)

Convert I915_READ*_NOTRACE to use DRM_READ*.

(riastradh)

i915_drv.h needs <linux/completion.h> and <linux/shrinker.h>.

(riastradh)

Add DRM_WAITERS_P and DRM_SPIN_WAITERS_P to drm_wait_netbsd.h.

(riastradh)

Add stub <linux/shrinker.h>.

Abstraction for the system to request that caches be shrunk.
Currently does nothing.

(riastradh)

Add <linux/completion.h>.

A completion is a synchronized waitable `done' flag.  Trivial
condvar/mutex/bool.

(riastradh)

Convert i915_driver_load to linux_mutex_init, and destory in unload.

(riastradh)

Convert i915_get_bridge_dev to use pci_kludgey_find_dev.

(riastradh)

Convert capable(CAP_SYS_ADMIN) to DRM_SUSER() in i915_getparam.

(riastradh)

Use dev->irq_enabled, not dev->pdev->irq, in i915_getparam.

The drm irq establishment code maintains dev->irq_enabled, and this
way we need not maintain it separately in the pci layer.

(riastradh)

Convert struct intel_ringbuffer::irq_queue to drm waitqueues.

(riastradh)

Add bool virtual_start_mapped to struct intel_ring_buffer.

The nullable pointer virtual_start was replaced by a struct
drm_local_map, which can't be null (well, perhaps we could abuse one
of the fields in it for that purpose, but this is cleaner), so
virtual_start_mapped will be maintained in the place of the
possibility of a null virtual_start to indicate whether the mapping
is present.

(riastradh)

Convert dri1 gfx_hws_cpu from ioremap to drm_ioremap.

(riastradh)

Ifdef out Linux vga stuff from i915_dma.c.

(riastradh)

Ifdef out Linux framebuffer stuff from i915_dma.c.

(riastradh)

Add a default (panic) case to DRM_IS_BUS_SPACE_P in drmP.h.

(riastradh)

Add pci_set_master to <linux/pci.h>.

(riastradh)

Add kludgey non-delayed work to <linux/workqueue.h>.

(riastradh)

Add THIS_MODULE (expanding to 0) to <linux/module.h>.

(riastradh)

Add upper_32_bits and lower_32_bits to <linux/kernel.h>.

(riastradh)

Add some conversion and comparison stuff to <linux/jiffies.h>.

(riastradh)

Implement udelay (DELAY) and msleep (kpause) in <linux/delay.h>.

(riastradh)

Make Linux WARN_* macros expand to expressions, not statements.

These are to return the value of the condition.

(riastradh)

Add some consts to i915/dvo_ch7xxx.c for string literals.

(riastradh)

Fix sense of refcount decrement conditional in drm_iounmap.

Add some kasserts just in case.

(riastradh)

Add stubs for pci_enable_msi and pci_disable_msi to <linux/pci.h>.

(riastradh)

Add field to struct pci_dev for the PCI device number.

(riastradh)

Add pci_kludgey_find_dev to <linux/pci.h>.

This is not a Linux KPI, but the Linux KPI (pci_get_bus_and_slot)
doesn't pass along the original pci device or bus, so this is what
we'll use to replace uses of it (or, the one use of it) without
changing much code.

(riastradh)

Add __always_unused and round_up to <linux/kernel.h>.

(riastradh)

Add pci_bus_alloc_resource to <linux/pci.h>.

(riastradh)

Add <linux/ioport.h> with struct resource: keeps bus_space_alloc books.

(riastradh)

Add pci_config_{read,write}_dword to <linux/pci.h>.

(riastradh)

Ifdef out field bit_algo of struct intel_gmbus.

XXX Revisit this with the rest of i2c cruft...

(riastradh)

Fill in <linux/acpi_io.h> with acpi_os_ioremap (= AcpiOsMapMemory).

Define __acpi_iomem as an empty frotz to replace the Linux __iomem
attribute selectively and greppably.  AcpiOsMapMemory returns usable
kernel virtual addresses, so we don't need to use bus_space_mumble or
anything to dereference them.

(riastradh)

Switch intel_ring_buffers from Linux ioremap to drm_ioremap.

(riastradh)

intel_ringbuffer.h needs <asm/bug.h>.

(riastradh)

Replace i915 private regs from pci_ioremap to drm_ioremap.

Replace read/write{b,l,w} by DRM_READ/WRITE{8,16,32} in i915_drv.c.

(riastradh)

Ifdef out Linux intel_ips kludge in intel_pm.c.

(riastradh)

Hook drm_edid.c back into the drm2 module build.

drm2.kmod now has no more undefined drm_* symbols!

(riastradh)

Fix const in drm_match_cea_mode in drm_edid.c.

(riastradh)

Avoid shadowing global edid_vendor in drm_edid.c.

(riastradh)

drm_edid.c needs <linux/device.h> for dev_warn.

(riastradh)

Add dev_warn (= device_printf, for now) to <linux/device.h>.

(riastradh)

Ifdef out Linux i2c stuff in drm_edid.c, to be rewritten.

(riastradh)

Clumsily avoid Linux print_hex_dump in drm_edid.c.

(riastradh)

drm_edid.c needs to include some more header files.

(riastradh)

Add Linux <asm/byteorder.h> with cpu_to_le16 &c.

(riastradh)

Define uninitialized_var in <linux/kernel.h>.

(riastradh)

Fix #endif comment in Linux <asm/bug.h>.

(riastradh)

Add linux_list_sort.c implementing list_sort.

Algorithm is merge sort using binary counting in a temporary array of
64 elements on the stack, big enough for any list that'll fit into
memory in a 64-bit address space, but small enough to fit comfortably
on the stack.

(riastradh)

Hook drm_modes.c back into the drm2 module build.

(riastradh)

Ifdef out Linux framebuffer commandline parsing in drm_modes.c.

(riastradh)

Ifdef out apparently unused drm_mode_validate_clocks in drm_modes.c.

(riastradh)

Define PICOS2KHZ and KHZ2PICOS in <linux/fb.h>.

(riastradh)

Include just <sys/types.h>, not <sys/systm.h>, in <linux/kernel.h>.

(riastradh)

Add local drm_gem_vm.c, utilities for mapping gem objects into vm.

(riastradh)

Hook drm_gem.c back into the build.

(riastradh)

Add local drm_vm.c with uvm-style (but non-gem) drm page mapping.

(riastradh)

Ifdef out the Linux-style vm routines in drm_gem.c.

(riastradh)

Manage the relevant uvm objects in gem object creation/destruction.

(riastradh)

Destroy the idr and spin lock in drm_gem_destroy.

(riastradh)

Adjust fields of struct drm_gem_object for uvm.

Add a struct uvm_object pointer gemo_uao for an anonymous object to
back shared memory, and a struct uvm_object gemo_uvmobj for custom
device page mapping.

In struct drm_driver, replace the Linux VM operations gem_vm_ops by
NetBSD UVM operations gem_uvm_ops, so that the compiler will catch
any extant references to the Linux structure that will need changing.

(riastradh)

Remove drm prime stuff from drm_gem.c.

(riastradh)

Ifdef out some drm prime stuff in drmP.h.

(riastradh)

Add idr_for_each to Linux idr abstraction.

(riastradh)

Add BUG() to Linux <asm/bug.h>.

(riastradh)

Use e_vm_default_addr to choose a default address in Linux vm_mmap.

(riastradh)

Use bus_addr_t, not bus_size_t, for resource_size_t; add phys_addr_t.

(riastradh)

Tag the spinlock struct in <linux/spinlock.h>.

(riastradh)

Define barrier() as __insn_barrier() in <linux/kernel.h>.

(riastradh)

Add stub definition of __must_check to <linux/kernel.h>.

(riastradh)

Make container_of type-safe with the help of a judicious sizeof.

Still avoids multiple evaluation of the pointer operand expression.

(riastradh)

Insert a strategic cast into agp_find_bridge.

(riastradh)

Add i915drm2 module.

(riastradh)

Add an i915drm device stub to files.drm2, attaching at pci.

(riastradh)

Hook local drm_scatter.c into the build.

(riastradh)

Add XXX comment to obviously broken error branch in drm_addmap_core.

(riastradh)

Omit __drm_pci_free.  Use kmem for drm_dma_handles now that we can.

(riastradh)

For _DRM_CONSISTENT maps, hang the dmah on the drm_local_map.

The way the Linux code does it is a bookkeeping kludge that falls
down when we want to maintain more than just the PCI bus address, as
drm mmap will want in order to avoid vtophys.

(riastradh)

Update drm_memory.c to reflect drm_local_map tagged union changes.

(riastradh)

Add operations to drmP.h for access to drm_local_map memory or I/O.

(riastradh)

Replace extra data in struct drm_local_map by a union.

This is a tagged union; only certain variants, specified by the map's
type, need a bus space handle and a drm bus map.  They will also need
a bus space tag later.  Other variants use other data, with more to
be added in the future, probably.

(riastradh)

Add local drm_scatter.c.

(riastradh)

Ifdef out calls to drm_sysfs_connector_remove in drm_crtc.c.

Revisit later, perhaps.

(riastradh)

Ifdef out call to drm_sysfs_hotplug_event in drm_crtc_helper.c.

(riastradh)

Add agp bridge data argument to drm_*_agp in local drm_fops.c.

(riastradh)

Add agp bridge data argument to drm_*_agp in drm_agpsupport.c.

(riastradh)

Add drm_bind_agp, drm_unbind_agp, & drm_free_agp to drm_agp_netbsd.h.

These have an extra argument for the agp bridge descriptor, as
NetBSD's AGP KPI requires.

Omit declarations of drm_bind_agp, drm_unbind_agp, and drm_free_agp
from drmP.h, now that these are all declared (and defined) in
drm_agp_netbsd.h instead.

(riastradh)

Ctassert that AGP_PAGE_SIZE == PAGE_SIZE in drm_agp_netbsd.h.

Linux assumes this.

(riastradh)
