2014-01-07freedreno: allow IB to different ringbufferRob Clark
Allow IB to different ringbuffer in addition to just different part of same ringbuffer. In particular, we need to add bo's to the parent (ie. one passed to flush) bo table, since the bo table applies to all the cmd buffers in submit ioctl. Signed-off-by: Rob Clark <robclark@freedesktop.org>

2013-12-13freedreno: add bo cacheRob Clark
Workloads which create many transient buffers cause significant CPU overhead in buffer allocation, zeroing, cache maint, and mmap setup. By caching and re-using existing buffers, the CPU overhead drops significantly. See: http://bloggingthemonkey.blogspot.com/2013/09/freedreno-update-moar-fps.html A simple time based policy is used for purging the cache. Once the kernel supports it, we could use madvise style API to handle memory pressure scenarios a bit better. Signed-off-by: Rob Clark <robclark@freedesktop.org>

2013-08-30freedreno: set automake options to include subdir-objectsEmil Velikov
Handles automake complains about lack of forward-compatibility, due to the source files in the kgsl and msm backends/folders. Cc: Rob Clark <robclark@freedesktop.org> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>
2013-08-30freedreno: use local drm.h over the system oneEmil Velikov
Otherwise build will fail, as drm/drm.h is not available. Cc: Rob Clark <robclark@freedesktop.org> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>
2013-08-28freedreno: add support for msm drmRob Clark
This adds support for the "msm" backend, using the upstream msm drm/kms driver. Signed-off-by: Rob Clark <robclark@freedesktop.org>
2013-08-28freedreno: support either kgsl or msmRob Clark
Split out common code and backend. Current backend is for 'kgsl' android driver, but a new backend will provide support for the upstream msm drm/kms driver. Signed-off-by: Rob Clark <robclark@freedesktop.org>
2013-05-17freedreno: also remove from name table on bo deleteRob Clark
When adding the name tracking, I missed removing from the name table when the bo was deleted, leaving a dangling pointer. Signed-off-by: Rob Clark <robclark@freedesktop.org>
2013-05-15freedreno: add some assertsRob Clark
Things are worse if we issueibcmds with bogus gpu ptrs, so it is better to just make userspace crash when things go pear shaped. Signed-off-by: Rob Clark <robclark@freedesktop.org>
2013-05-15freedreno: add handle and name trackingRob Clark
Due to the evil userspace buffer tracking we have to do, and hacks for creating GEM buffer from fbdev/scanout, "evil-twin" fd_bo objects are problematic. So introduce hashtable tracking of bo's and dev's, to avoid getting duplicate fd_bo ptrs for the same underlying gem object, in particular when importing via flink name.

2013-04-25freedreno: add synchronization between mesa and ddxRob Clark
Super-cheezy way to synchronization between mesa and ddx.. the SET_ACTIVE ioctl gives us a way to stash a 32b # w/ a GEM bo, and GET_BUFINFO gives us a way to retrieve it. We use this to stash the timestamp of the last ISSUEIBCMDS on the buffer. To avoid an obscene amount of syscalls, we: 1) Only set the timestamp for buffers w/ an flink name, ie. only buffers shared across processes. This is enough to catch the DRI2 buffers. 2) Only set the timestamp for buffers submitted to the 3d ring and only check the timestamps on buffers submitted to the 2d ring. This should be enough to handle synchronizing of presentation blit. We could do synchronization in the other direction too, but that would be problematic if we are using the 3d ring from DDX, since client side wouldn't know this. The waiting on timestamp happens before flush, and setting of timestamp happens after flush. It is transparent to the user of libdrm_freedreno as all the tracking of buffers happens via _emit_reloc().. Signed-off-by: Rob Clark <robclark@freedesktop.org>
2013-04-22freedreno: add gpu-id propertyRob Clark
Gallium driver will need to query this to figure out whether to load the a2xx or a3xx driver. Signed-off-by: Rob Clark <robclark@freedesktop.org>
2013-04-13freedreno: add shifted relocRob Clark
Needed for RB_COPY_DEST_BASE register on a3xx. Signed-off-by: Rob Clark <robdclark@gmail.com>

2013-02-14freedreno: add freedreno DRMRob Clark
The libdrm_freedreno helper layer for use by xf86-video-freedreno, fdre (freedreno r/e library and tests for driving gpu), and eventual gallium driver for the Adreno GPU. This uses the msm gpu driver from QCOM's android kernel tree. Note that current msm kernel driver is a bit strange. It provides a DRM interface for GEM, which is basically sufficient to have DRI2 working. But it does not provide KMS. And interface to 2d and 3d cores is via different other devices (/dev/kgsl-*). This is not quite how I'd write a DRM driver, but at this stage it is useful for xf86-video-freedreno and fdre (and eventual gallium driver) to be able to work on existing kernel driver from QCOM, to allow to capture cmdstream dumps from the binary blob drivers without having to reboot. So libdrm_freedreno attempts to hide most of the crazy. The intention is that when there is a proper kernel driver, it will be mostly just changes in libdrm_freedreno to adapt the gallium driver and xf86-video-freedreno (ignoring the fbdev->KMS changes). So don't look at freedreno as an example of how to write a libdrm module or a DRM driver.. it is just an attempt to paper over a non- standard kernel driver architecture. v1: original v2: hold ref's to pending bo's (because qcom's kernel driver doesn't), various bug fixes, add ringbuffer markers so we can emit IB's to portion of ringbuffer (so that gallium driver can use a single ringbuffer for both tile cmds and draw cmds.
