The point here isn't code prettification (it helps with that too) but that some of these lists aren't static any more. And having macros will gives us a convenient place to put locking checks into. I didn't add an iterator for props since that's only used by a list_for_each_entry_safe in the driver teardown code. Search&replace was done with the below cocci spatch. Note that there's a bunch more places that didn't match and which would need some manual changes, but I've intentially left these out for this mostly automated patch. iterator name drm_for_each_crtc; struct drm_crtc *crtc; struct drm_device *dev; expression head; @@ - list_for_each_entry(crtc, &dev->mode_config.crtc_list, head) { + drm_for_each_crtc (crtc, dev) { ... } @@ iterator name drm_for_each_encoder; struct drm_encoder *encoder; struct drm_device *dev; expression head; @@ - list_for_each_entry(encoder, &dev->mode_config.encoder_list, head) { + drm_for_each_encoder (encoder, dev) { ... } @@ iterator name drm_for_each_fb; struct drm_framebuffer *fb; struct drm_device *dev; expression head; @@ - list_for_each_entry(fb, &dev->mode_config.fb_list, head) { + drm_for_each_fb (fb, dev) { ... } @@ iterator name drm_for_each_connector; struct drm_connector *connector; struct drm_device *dev; expression head; @@ - list_for_each_entry(connector, &dev->mode_config.connector_list, head) { + drm_for_each_connector (connector, dev) { ... } Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>

Daniel and Ville don't want to expose 2 DRM planes and would rather expose a CURSOR plane that has all the usual plane properties, and that's a blocker for lifting the prelimary_hw_support flag. Unfortunately noone has had the time to finish this yet, but lifting the prelimary_hw_support flag is long overdue.

Otherwise we can only use it in a very restricted way: Initial modeset when the request mode is the preferred one of the panel and there's still a pfit active. And that only works because our mode_from_pipe_config fills in the wrong mode (it takes the adjusted mode, not the requested one). But we want fast modesets everywhere even after boot-up (especially for testing, but not only there). Hence we need to be able to make any modeset a fast one, which means we need to invert the logic and optionally downgrade a modeset. Note that this needs ->connector_changed split out from ->mode_changed otherwise it's not going to work (because we might loose a modeset because connectors changed but otherwise the config matches). As soon as that's merged we can drop the i915.fastboot check from this code. Also make sure that we don't accidentally clear any_ms and that we add the planes for any kind of modeset. Finally rename fastboot to fastset (yeah it's a silly name) since this really isn't about booting all that much.

But since the pipe_config quirk isn't tied to the lifetime of the mode object we need to check both. Simplify this by only using mode.private_flags and stop using the INHERITED_MODE quirk. Also for clarity add an explicit #define for that driver priavete mode flag. By using crtc_state->mode_changed we can also remove the recalc local variable.

The set of MOCS configuration entries introduced by this patch is intended to be minimal but sufficient to cover the needs of current userspace - i.e. a good set of defaults. It is expected to be extended in the future to provide further default values or to allow userspace to redefine its private MOCS tables based on its demand for additional caching configurations. In this setup, userspace should only utilize the first N entries, higher entries are reserved for future use. It creates a fixed register set that is programmed across the different engines so that all engines have the same table. This is done as the main RCS context only holds the registers for itself and the shared L3 values. By trying to keep the registers consistent across the different engines it should make the programming for the registers consistent. v2: -'static const' for private data structures and style changes.(Matt Turner) v3: - Make the tables "slightly" more readable.

Prefix L3-specific defines consistently with L3_ and e/LLC-specific defines with LE_ to avoid this kind of confusion in the future. - Change L3CC WT define back to RESERVED (matches my hardware documentation and the original patch, probably a misunderstanding of my own previous comment). - Drop Android tables, define new minimal tables more suitable for the open source stack. - Add comment that the MOCS tables are part of the kernel ABI. - Move intel_logical_ring_begin() and _advance() calls one level down (Chris Wilson). - Minor formatting and style fixes. v8 (Francisco Jerez): - Add table size sanity check to emit_mocs_control/l3cc_table() (Chris Wilson). - Add comment about undefined entries being implicitly set to uncached for forwards compatibility. v9 (Francisco Jerez): - Minor style fixes.

Use this to force a modeset. Only during modesets, or with PIPE_CONFIG_QUIRK_INHERITED_MODE we should check if a full modeset is really needed. Fastboot will allow the adjust parameter to ignore some stuff too, and it will fix up differences in state that are ignored by the compare function. Changes since v1: - Increase the value of the lowest m/n to prevent truncation. - Dump pipe config when fastboot's used, without a modeset. - Add adjust parameter to intel_compare_link_m_n, which is used to adjust m2_n2 if it's a multiple of m_n. - Add exact parameter intel_compare_m_n.

Instead just disable all scalers when disabling. It's probably good enough to just disable the crtc_scaler, but just in case there's a bug disable all scalers. This means intel_atomic_setup_scalers is only called in the crtc check function now, so all the transitional code can be removed.

These extra interrupts might waste some cpu cycles. This patch corrects this by masking interrupts prior to updating the frequency. Note from Chris: "Well it won't waste CPU cycles as the interrupt is also masked by the threshold limits, but there should be no harm at all in reordering the patch so, and it does make a certain amount of sense."
