* drm: Improve drm_mm search (and fix topdown allocation) with rbtreesChris Wilson2017-02-032-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drm_mm range manager claimed to support top-down insertion, but it was neither searching for the top-most hole that could fit the allocation request nor fitting the request to the hole correctly. In order to search the range efficiently, we create a secondary index for the holes using either their size or their address. This index allows us to find the smallest hole or the hole at the bottom or top of the range efficiently, whilst keeping the hole stack to rapidly service evictions. v2: Search for holes both high and low. Rename flags to mode. v3: Discover rb_entry_safe() and use it! v4: Kerneldoc for enum drm_mm_insert_mode.

* drm: Rely on mode_config data for fb_helper initializationGabriel Krisman Bertazi2017-02-021-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

Ie. vblank irq would trigger event and userspace could begin the next atomic update, before the commit worker had a chance to clear the pending flag. If we do end up needing something to prevent userspace from trying another pageflip before getting vblank event, it should probably be implemented as a pending_planes bitmask, similar to pending_crtcs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the value written to CP_RB_WPTR is calculated on the fly as (rb->next - rb->start). But as the code is designed rb->next is wrapped before writing the commands so if a series of commands happened to fit perfectly in the ringbuffer, rb->next would end up being equal to rb->size / 4 and thus result in an out of bounds address to CP_RB_WPTR. The easiest way to fix this is to mask WPTR when writing it to the hardware; it makes the hardware happy and the rest of the ringbuffer math appears to work and there isn't any point in upsetting anything.

The more annoying part with no pull request for 4 weeks is managing cross-tree work. The -intel pull request I'll follow up with does conflict quite a bit with -misc here. Longer-term (if drm-misc keeps growing) a drm-next-queued to accept pull request for the next merge window during this time might be useful.

| | * drm/msm: gpu: Add support for the GPMUJordan Crouse2016-11-286-3/+431
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most 5XX targets have GPMU (Graphics Power Management Unit) that handles a lot of the heavy lifting for power management including thermal and limits management and dynamic power collapse. While the GPMU itself is optional, it is usually nessesary to hit aggressive power targets. The GPMU firmware needs to be loaded into the GPMU at init time via a shared hardware block of registers. Using the GPU to write the microcode is more efficient than using the CPU so at first load create an indirect buffer that can be executed during subsequent initalization sequences. After loading the GPMU gets initalized through a shared register interface and then we mostly get out of its way and let it do its thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new generic function to write a "64" bit value. This isn't actually a 64 bit operation, it just writes the upper and lower 32 bit of a 64 bit value to a specified LO and HI register. If a particular target doesn't support one of the registers it can mark that register as SKIP and writes/reads from that register will be quietly dropped. This can be immediately put in place for the ringbuffer base and the RPTR address. Both writes are converted to use adreno_gpu_write64() with their respective high and low registers and the high register appropriately marked as SKIP for both 32 bit targets (a3xx and a4xx). When a5xx comes it will define valid target registers for the 'hi' option and everything else will just work.

For 4XX and older these are normally perfcounter registers, but future targets will use 64 bit addressing so there will be many more spots where a 64 bit read and write are needed. gpu_rmw() does a read/modify/write on a 32 bit register given a mask and bits to OR in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, SMP block allocation was not checked in the plane's atomic_check() fxn, so we could fail allocation SMP block allocation at atomic_update() time. Re-work the block allocation to request blocks during atomic_check(), but not update the hw until committing the atomic update. Since SMP blocks allocated at atomic_check() time, we need to manage the SMP state as part of mdp5_state (global atomic state). This actually ends up significantly simplifying the SMP management, as the SMP module does not need to manage the intermediate state between assigning new blocks before setting flush bits and releasing old blocks after vblank. (The SMP registers and SMP allocation is not double-buffered, so newly allocated blocks need to be updated in kms->prepare_commit() released blocks in kms->complete_commit().)

SMP block reallocation). This means all planes advertise the superset of formats and properties. Userspace must (as always) use atomic TEST_ONLY step for atomic updates, as not all planes may be available for use on every frame. The mapping of hwpipe to plane is stored in mdp5_state, so that state updates are atomically committed in the same way that plane/etc state updates are managed. This is needed because the mdp5_plane_state keeps a pointer to the hwpipe, and we don't want global state to become out of sync with the plane state if an atomic update fails, we hit deadlock/ backoff scenario, etc. The use of state_lock keeps multiple parallel updates which both re-assign hwpipes properly serialized.
