Use the actual tile size as to compute stuff in intel_fill_fb_ggtt_view() instead of assuming it's PAGE_SIZE. I suppose it doesn't matter since we don't use the results on gen2 platforms where the tile size is 2k. v2: Update due to CbCr plane Signed-off-by:

I find more usual to think about tile widths than heights, so changing the intel_tile_height() to calculate the tile height as tile_size/tile_width is easier than the opposite to the poor brain. v2: Reorder arguments for consistency Constify dev_priv arguments Signed-off-by: -

Pull the tile width calculations from intel_fb_stride_alignment() into a new function intel_tile_width(). Also take the opportunity to pass aroun dev_priv instead of dev to intel_fb_stride_alignment(). v2: Reorder argumnents to be more consistent with other functions Change intel_fb_stride_alignment() to accept dev_priv instead of dev v3: Deal with Y tilling (Daniel) Signed-off-by: -

Majority of them was duplicated code and only render ring currently overrides some of them. We can save some lines of code and also take away the confusion on why bsd2 did not do the seqno coherency workaround. (VCS2 ring does not exist on platforms where workaround is needed but that was not documented in the code.) Signed-off-by:

Kernel and userspace are able to handle 4GB (1<<32) address space range, but "A32 Stateless Model" is not. According to documentation, A32 accesses are based on General State Base Address and bound checking is in place. Because size field (instruction State Base Address) limitation, it is not possible to address full 4GB memory region. A32 Stateless Model is used by some libraries and without this patch, the last page of 4GB address space is not accessible in 32bit processes. Reported-by:

sanitize_watermarks() does not properly handle errors returned by drm_atomic_helper_duplicate_state(). Make failures drop locks before returning. We also change the lock of connection_mutex to a drm_modeset_lock_all_ctx() to make sure any EDEADLK's are handled earlier. v2: Change call to lock connetion_mutex with a call to drm_modeset_lock_all_ctx(). This ensures that any lock contention is handled earlier and drm_atomic_helper_duplicate_state() won't return EDEADLK. (Maarten) v3: Drop locks properly in more error paths.

commit 10afa0b6 ("drm/i915: Reject >9 ddi translation entried if port != A/E on SKL") added sanity checks to make sure we don't end up with too many ddi translation values for eDP ports, but it actually failed to check if the port is eDP. We still look up the edp translations for non-eDP ports, but don't use them, so we shouldn't be complaining about them either.

MI_BATCH_BUFFER is nasty since it requires that userspace pass in the correct batch length. Let's switch to using MI_BATCH_BUFFER_START instead (like we do on other platforms). Then we don't have to specify the batch length at all, and the CS will instead execute until it sees the MI_BATCH_BUFFER_END. We still need the batch length since we do the CS TLB workaround and copy the batch into the permanently pinned scratch object and execute it from there. But for this we can simply use the batch object length when the user hasn't specified the actual batch length. So specifying the batch length becomes just a way to optimize the batch copy a little bit. We lost batch_len from a bunch of igts (including the quiesce batch) so without this igt is utterly broken on 830/845. Also some igts such as gem_cpu_reloc never specified the batch_len and so didn't work. With MI_BATCH_BUFFER_START we don't have to fix up igt every time someone forgets that 830/845 exist.

My 85x has VBT version 108 which has a child dev size of 27 bytes. Let's allow that without printing an error. We still want to reject the actual parsin since for that we need the child device size to be at least 33 bytes. So we should still check for that, but let's make it print a debug message only instead of an error. While at it, toss in a BUILD_BUG_ON() to verify our struct old_child_dev_config is in fact 33 bytes. Signed-off-by:

We use the vblank timestamps to generate the vblank frame counter value on gen2. That means we need the pipe scanout position to be accurate when we call drm_crtc_vblank_on(), otherwise the frame counter guesstimate may jump when the pipe actually start. What I observed on my 85x is that the DSL initially reads 0, and when the pipe actually starts DSL jumps to vblank_start. On gen2 DSL==0 means actually vtotal-1 (see update_scanline_offset()), so if we initially get vtotal-1, and then very quickly vblank_start (or thereabouts), the scanout position will appear to jump backwards by approximately one vblank length. Which means the frame counter guesstimate will also jump backwards. That's no good, so let's make sure the pipe has started before we call drm_crtc_vblank_on(). Signed-off-by:

We're supposed to pass the primary DP encoder to intel_ddi_clk_select(), not the fake MST encoder. Do so. There's no real bug here though, since intel_ddi_clk_select() only checks if the encoder type is EDP (which it isn't for either the primary DP encoder or the fake MST encoder), and it gets the DDI port via intel_ddi_get_encoder_port() (which knows how to do the fake->primary->port dance itself).

The sequence block has sizes of elements after the operation byte since sequence block v3. Use it to skip elements we don't support yet. v2: remove redundant exec_elem[operation_byte] check (Daniel) Reviewed-by:
-
Jani Nikula authored
The changes since the sequence block v2 are: * The whole MIPI bios data block has a separate 32-bit size field since v3, stored after the version. This facilitates big sequences. * The size of the panel specific sequence blocks has grown to 32 bits. This facilitates big sequences. * The elements within sequences now have an 8-bit size field following the operation byte. This facilitates skipping unknown new operation bytes, i.e. forward compatibility. v2 (of the patch): use DRM_ERROR for unknown operation byte v3 (of the patch): even more bounds checking (Ville) Reviewed-by:

If we go into suspend with unclaimed access detected, it would be nice to catch that access on a next suspend path. So instead of just notifying about it, arm the unclaimed mmio checks on suspend side. We want to keep the asymmetry on resume, as if it was on resume path, it was not driver that is responsible so no point in arming mmio debugs.

With commit 8ac3e1bb ("drm/i915: Add non claimed mmio checking for vlv/chv") we now have chv/vlv support in place for detecting unclaimed access. Also the perf hit of extra mmio read is now only suffered if mmio_debug is set. This allows us to stuff the macro for unclaimed reg detection inside a generic gen6 register access, as now all gens using these macros uses also unclaimed debugs, the one exception being snb. We gain more clean and generic macros and only downside is that snb will suffer one branch perf hit without upside. Note that the hsw write path debug register check now happens before fifo check, but this should not make any real difference. As vlv/chv use the generic gen6 access macros, the consequence is that they gain the mmio_debug feature.
