2014-03-05freedreno/kgsl: don't even bother trying CREATE_FDRob Clark
Don't even bother trying DRM_KGSL_GEM_CREATE_FD. It hasn't worked since (afaict) 2.6.35 kernels. And in some cases seems to cause some problems. Instead just allocate a minimum size dummy object (just for purposes of having a handle) and then mmap the framebuffer as user-mem (which is deprecated, but seems to still work.. and as far as I can tell is the best option for now).

2014-01-12freedreno: add fd_device_new_dup()Rob Clark
There seem to be some cases (I've noticed this switching resolution in some games, for example) where the fd can get closed() before the device and all it's bo's are destroyed. Which, if the drm device is opened again and bo's are allocated with the same handles, results that when the first pipe_screen/pipe_context is destroyed causes the first dev to close handles for bo's allocated by the second device. The easy solution to that is to add a mode where the fd_device creates it's own private fd (a dup()). Signed-off-by: Rob Clark <robclark@freedesktop.org>
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>

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>

2013-02-14freedreno: 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.
