gmux has 3 switch registers: * GMUX_PORT_SWITCH_DISPLAY switches the panel * GMUX_PORT_SWITCH_DDC switches the panel's DDC lines (only on pre-retinas; on retinas this is a no-op) * GMUX_PORT_SWITCH_EXTERNAL switches the external DP port(s) (only on models without Thunderbolt, i.e. introduced before 2011; those with Thunderbolt switch only HPD/AUX, not the main link) Currently we switch all 3 registers in unison. gmux does not preserve the switch state during suspend, so we currently read GMUX_PORT_SWITCH_DISPLAY before suspend and restore all 3 registers to this value on resume. With the upcoming ->switch_ddc callback, GMUX_PORT_SWITCH_DDC may temporarily contain a different value than the other 2 registers. If we happen to suspend at this moment, we'll write an incorrect value to GMUX_PORT_SWITCH_DDC on resume. Also, on models with Thunderbolt the integrated GPU is unable to drive the external DP port(s), so we want to keep GMUX_PORT_SWITCH_EXTERNAL permanently switched to the discrete GPU on those machines. Consequently we can no longer assume that GMUX_PORT_SWITCH_DISPLAY represents the correct value for all 3 registers on suspend. Track the state of all 3 registers: Add gmux_read_switch_state() and gmux_write_switch_state(). Instead of reading the switch state on every suspend, read it once on driver initialization so that we know the current switch state all the time. (This allows us to use some optimizations and shortcuts, e.g. we can skip switching DDC if we know that it's already switched to the requested GPU.) Change the ->switchto callback to use gmux_write_switch_state(). Tested-by:

Originally by Seth Forshee <seth.forshee@canonical.com>, 2012-10-04: During graphics driver initialization it's useful to be able to mux only the DDC to the inactive client in order to read the EDID. Add a switch_ddc callback to allow capable handlers to provide this functionality, and add vga_switcheroo_switch_ddc() to allow DRM to mux only the DDC.

Original version tried to determine previous DDC owner with find_active_client() but this fails if the inactive client registers before the active client. Don't lock vgasr_mutex in _lock_ddc() / _unlock_ddc(), it can cause deadlocks because (a) during switch (with vgasr_mutex already held), GPU is woken and probes its outputs, tries to re-acquire vgasr_mutex to lock DDC lines; (b) Likewise during switch, GPU is suspended and calls cancel_delayed_work_sync() to stop output polling, if poll task is running at this moment we may wait forever for it to finish. Instead, lock mux_hw_lock when unregistering the handler because the only reason why we'd want to lock vgasr_mutex in _lock_ddc() / _unlock_ddc() is to block the handler from disappearing while DDC lines are switched. Also acquire mux_hw_lock in stage2 to avoid race condition where reading the EDID and switching happens simultaneously. Likewise on MIGD / MDIS commands and on runtime suspend. v2.1: Overhaul locking, squash commits (Daniel Vetter) v2.2: Readability improvements (Thierry Reding) v2.3: Overhaul locking once more v2.4: Retain semantics of ->switchto handler callback to switch all pins, including DDC (Daniel Vetter) v5: Rename ddc_lock to mux_hw_lock: Since we acquire this both when calling ->switch_ddc and ->switchto, it protects not just access to the DDC lines but to the mux in general. This is in line with the DRM convention to use low-level locks to avoid concurrent hw access (e.g. i2c, dp_aux) which are often called hw_lock (Daniel Vetter) Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=88861 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=61115Tested-by: -

Allow handlers to declare their capabilities and allow clients to obtain that information. So far we have these use cases: * If the handler is able to switch DDC separately, clients need to probe EDID with drm_get_edid_switcheroo(). We should allow them to detect a capable handler to ensure this function only gets called when needed. * Likewise if the handler is unable to switch AUX separately, the active client needs to communicate link training parameters to the inactive client, which may then skip the AUX handshake and set up its output with these pre-calibrated values (DisplayPort specification v1.1a, section 2.5.3.3). Clients need a way to recognize such a situation. The flags for the radeon_atpx_handler and amdgpu_atpx_handler are initially set to 0, this can later on be amended with handler_flags |= VGA_SWITCHEROO_CAN_SWITCH_DDC; when a ->switch_ddc callback is added.

This function is meant to be used with dma-buf mmap, when finishing the CPU access of the mapped pointer.

So we use a uninterruptible mutex_lock to spit out when it ever happens. v2: disable interruption to make sure errors are reported. v3: update to the new end_cpu_access API. v7: use .write = false cause it doesn't need to know whether it's write.

This patch removes range-based information used for optimizations in begin_cpu_access and end_cpu_access. We don't have any user nor implementation using range-based flush. It seems a consensus that if we ever want something like that again (or even more robust using 2D, 3D sub-range regions) we can use the upcoming dma-buf sync ioctl for such.

Currently DRM_IOCTL_PRIME_HANDLE_TO_FD rejects all flags except (DRM|O)_CLOEXEC making it difficult (maybe impossible) for userspace to mmap() the resulting dma-buf even when this is supported by the DRM driver. It is trivial to relax the restriction and permit read/write access. This is safe because the flags are seldom touched by drm; mostly they are passed verbatim to dma_buf calls. v3 (Tiago): removed unused flags variable from drm_prime_handle_to_fd_ioctl. Reviewed-by:

Again since the drm core takes care of event unlinking/disarming this is now just needless code. v2: I've completely missed eaction->fpriv_head and all the related code. We need to nuke that too to avoid accidentally deferencing the freed-up vmwgfx-private fpriv. v3: Also remove vmw_fpriv->fence_events and unused variables I missed.
