Now that adjusted_mode.clock no longer contains the pixel_multiplier, we can kill the get_clock() callback and instead do the clock readout in get_pipe_config(). Also i9xx_crtc_clock_get() can now extract the frequency of the PCH DPLL, so use it to populate port_clock accurately for PCH encoders. For DP in port A the encoder is still responsible for filling in port_clock. The FDI adjusted_mode.clock extraction is kept in place for some extra sanity checking, but we no longer need to pretend it's also the port_clock. In the encoder get_config() functions fill out adjusted_mode.clock based on port_clock and other details such as the DP M/N values, HDMI 12bpc and SDVO pixel_multiplier. For PCH encoders we will then do an extra sanity check to make sure the dotclock we derived from the FDI configuratiuon matches the one we derive from port_clock. DVO doesn't exist on PCH platforms, so it doesn't need to anything but assign adjusted_mode.clock=port_clock. And DDI is HSW only, so none of the changes apply there. v2: Use hdmi_reg color format to detect 12bpc HDMI case v3: Set adjusted_mode.clock for LVDS too v4: Rename ironlake_crtc_clock_get to ironlake_pch_clock_get, eliminate the useless link_freq variable.

Add the 120MHz refernce clock case for PCH DPLLs. Also determine the reference clock frequency more accurately by checking for the PLLB_REF_INPUT_SPREADSPECTRUMIN refclk input mode. The gen2 code already checked it, but it stil assumed a fixed 66MHz refclk. Instead we need to consult the VBT for the real value. v2: Fix refclk for SSC panel case Signed-off-by:

We already extract the DPLL state to pipe_config, so let's make use of it in i9xx_crtc_clock_get() and avoid the register reads. This will also make the function closer to being useable with PCH DPLL since the registers for those live in a different address. Also kill the useless adjusted_mode.clock zeroing. It's already zero at this point. v2: Read out DPLL state in intel_crtc_mode_get() Signed-off-by:

Extract the code to calculate the dotclock from the link clock and M/N values into a new function from ironlake_crtc_clock_get(). The new function can be used to calculate the dotclock for both FDI and DP cases. Also simplify the code a bit along the way. v2: Don't forget about non-pch encoders in ironlake_crtc_clock_get() Signed-off-by:

We always read a register for l3 parity reads, and we don't really want to ever let userspace trick us into giving back less than the dword. Writes are okay because we assume everything will be 0 filled, and as such, if a user really wants to write less than a dword, let them. Signed-off-by:

Add functions to read out the CPU and PCH transcoder M/N values, and use them to fill out the pipe config dp_m_n information. And while at it populate has_dp_encoder too.

It would be easier if adjusted_mode.clock would be the pipe pixel clock, and it actually is, except for the cases where pixel_multiplier > 1. So let's change intel_sdvo to use port_clock as the multiplied clock, and then we can leave adjusted_mode.clock as pipe pixel clock. v2: Improve port_clock documentation Rebased on top of SDVO pixel_multiplier fixes Signed-off-by: -
Ville Syrjälä authored
We feed the non-multiplied clock to intel_link_compute_m_n(), so the opposite operation should use the same order of operations. So we just multiply by pixel_multiplier in the end now. Reviewed-by:

When reserving objects during execbuf, it is possible to come across an object which will not fit given the current fragmentation of the address space. We do not have any defragment in drm_mm, so the strategy is to instead evict everything, and reallocate objects. With the upcoming addition of multiple VMs, there is no point to evict everything since doing so is overkill for the specific case mentioned above. Recommended-by:

As we'll see in the next patch, being able to evict for just 1 VM is handy. Signed-off-by:

lifted from Daniel: pread/pwrite isn't about the object's domain at all, but purely about synchronizing for outstanding rendering. Replacing the call to set_to_gtt_domain with a wait_rendering would imo improve code readability. Furthermore we could pimp pread to only block for outstanding writes and not for reads. Since you're not the first one to trip over this: Can I volunteer you for a follow-up patch to fix this? v2: Switch the pwrite patch to use \!read_only. This was a typo in the original code.

Ignoring the legacy DRI1 code, and a couple of special cases (to be discussed later), all access to the ring is mediated through requests. The first write to a ring will grab a seqno and mark the ring as having an outstanding_lazy_request. Either through explicitly adding a request after an execbuffer or through an implicit wait (either by the CPU or by a semaphore), that sequence of writes will be terminated with a request. So we can ellide all the intervening writes to the tail register and send the entire command stream to the GPU at once. This will reduce the number of *serialising* writes to the tail register by a factor or 3-5 times (depending upon architecture and number of workarounds, context switches, etc involved). This becomes even more noticeable when the register write is overloaded with a number of debugging tools. The astute reader will wonder if it is then possible to overflow the ring with a single command. It is not. When we start a command sequence to the ring, we check for available space and issue a wait in case we have not. The ring wait will in this case be forced to flush the outstanding register write and then poll the ACTHD for sufficient space to continue. The exception to the rule where everything is inside a request are a few initialisation cases where we may want to write GPU commands via the CS before userspace wakes up and page flips.

Make the call to intel_update_watermarks() just once or twice during modeset. Ideally it should happen independently when each plane gets enabled/disabled, but for now it seems better to keep it in central place. We can improve things when we get all the planes sorted out in a better way. When enabling set up the watermarks just before the pipe is enabled. And when disabling we need to wait until we've marked the crtc as inactive, as otherwise intel_crtc_active() would still think the pipe is enabled and the computed watermarks would reflect that. v2: Pimp up the commit message a bit Reviewed-by:

Now when we have mechanism in place to track which context was guilty of hanging the gpu, it is possible to punish for bad behaviour. If context has recently submitted a faulty batchbuffers guilty of gpu hang and submits another batch which hangs gpu in quick succession, ban it permanently. If ctx is banned, no more batchbuffers will be queued for execution. There is no need for global wedge machinery anymore and it would be unwise to wedge the whole gpu if we have multiple hanging batches queued for execution. Instead just ban the guilty ones and carry on. v2: Store guilty ban status bool in gpu_error instead of pointers that might become danling before hang is declared. v3: Use return value for banned status instead of stashing state into gpu_error (Chris Wilson) v4: - rebase on top of fixed hang stats api - add define for ban period - rename commit and improve commit msg v5: - rely context banning instead of wedging the gpu - beautification and fix for ban calculation (Chris) Signed-off-by: -

It is possible for us to be forced to perform an allocation for the lazy request whilst running the shrinker. This allocation may fail, leaving us unable to reclaim any memory leading to premature OOM. A neat solution to the problem is to preallocate the request at the same time as acquiring the seqno for the ring transaction. This means that we can report ENOMEM prior to touching the rings.
