drm/r128: fix r128 ioremaps to use ioremap_wc.
drm: cleanup properly in drm_get_dev() failure paths
drm: clean the map list before destroying the hash table
drm: remove unreachable code in drm_sysfs.c
drm: add control node checks missing from kms merge
drm/kms: don't try to shortcut drm mode set function

|
|
This should allow r128 to start working again since PAT changes.

In current code we register/unregister connector object by
drm_sysfs_connector_add/remove function.
However under some cases, we need to dynamically register or unregister device
multiple times, so we have to go through register -> unregister ->register
routine.
Because after device_unregister function our memory is dirty, we need to do
clean operation in order to re-register the device, otherwise the system
will crash. The patch intends to clean device after device release.

This patch corrects a pretty big oversight in the KMS code for 965+
chips. The current code is missing tiled surface register programming,
so userland can allocate a tiled surface and use it for mode setting,
resulting in corruption. This patch fixes that, allowing for tiled
front buffers on 965+.

Save the bit 17 state of the pages when freeing the page list, and
reswizzle them if necessary when rebinding the pages (in case they were
swapped out). Since we have userland with expectations that the swizzle
enums let it pread and pwrite contents accurately, we can't expose a new
swizzle enum for bit 17 (which it would have to GTT map to handle), so we
handle it down in pread and pwrite by swizzling the copy when bit 17 of the
page address is set.

i915_gem_put_relocs_to_user returned an uninitialized value which
got returned to userspace. This caused libdrm in my setup to never
get out of a do{}while() loop retrying i915_gem_execbuffer.
result was hanging X, overheating of cpu and 2-3gb of logfile-spam.
This patch adresses the issue by
1. initializing vars in this file where necessary
2. correcting wrongly interpreted return values of copy_[from/to]_user

Currently we detect HDMI monitor by hardware detection, but if an HDMI-DVI
adapter is used to connect a DVI monitor, hardware detection will incorrectly
take monitor as HDMI. HDMI spec says any device containing IEEE registration
identifier will be treated as HDMI device. The patch intends to detect HDMI
monitor by drm_detect_hdmi_monitor function which follows that rule.

We create a debugfs node (i915_ringbuffer_data) to expose a hex dump
of the ring buffer itself. We also expose another debugfs node
(i915_ringbuffer_info) with information on the state (i.e. head, tail
addresses) of the ringbuffer.
For batchbuffer dumping, we look at the device's active_list, dumping
each object which has I915_GEM_DOMAIN_COMMAND in its read
domains. This is all exposed through the dri/i915_batchbuffers debugfs
file with a header for each object (giving the objects gtt_offset so
that it can be matched against the offset given in the
BATCH_BUFFER_START command.

This is a baby-step in the direction of having finer-grained

new debugging code to read the active list for printing out
GPU state when the GPU is wedged, (while the struct_mutex is
