While I thought I had this correct (since it actually did reject modes like I expected during testing), Ville Syrjala from Intel pointed out that the logic here isn't correct. max_clock refers to the max data rate supported by the DP encoder. So, limiting it to the output of ds_clock (which refers to the maximum dotclock of the downstream DP device) doesn't make any sense. Additionally, since we're using the connector's bpc as the canonical BPC we should use this in mode_valid until we support dynamically setting the bpp based on bandwidth constraints. https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html For more info. So, let's rewrite this using Ville's advice. v2: * Ville pointed out I mixed up the dotclock and the link rate. So fix that... * ...and also rename all the variables in this function to be more appropriately labeled so I stop mixing them up. * Reuse the bpp from the connector for now until we have dynamic bpp selection. * Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we should also have been doing from the start Signed-off-by:

Ville also pointed out that I got a lot of the logic here wrong as well, whoops. While I don't think anyone's likely using 3D output with nouveau, the next patch will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get rid of it and open-code it like before, while taking care to move the 3D frame packing calculations on the dot clock into the right place. Signed-off-by:

Not entirely sure why this never came up when I originally tested this (maybe some BIOSes already have this setup?) but the ->caps_init vfunc appears to cause the display engine to throw an exception on driver init, at least on my ThinkPad P72: nouveau 0000:01:00.0: disp: chid 0 mthd 008c data 00000000 0000508c 0000102b This is magic nvidia speak for "You need to have the DMA notifier offset programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix this by doing that, and also perform an update afterwards to prevent racing with the GPU when reading capabilities. v2: * Don't just program the DMA notifier offset, make sure to actually perform an update v3: * Don't call UPDATE() * Actually read the correct notifier fields, as apparently the CAPABILITIES_DONE field lives in a different location than the main NV_DISP_CORE_NOTIFIER_1 field. As well, 907d+ use a different CAPABILITIES_DONE field then pre-907d cards. v4: * Don't forget to check the return value of core507d_read_caps() v5: * Get rid of NV50_DISP_CAPS_NTFY[14], use NV50_DISP_CORE_NTFY * Disable notifier after calling GetCapabilities() Signed-off-by:

Restore RPS for ILK-M. We lost it when an extra HAS_RPS() check appeared in intel_rps_enable(). Unfortunaltey this just makes the performance worse on my ILK because intel_ips insists on limiting the GPU freq to the minimum. If we don't do the RPS init then intel_ips will not limit the frequency for whatever reason. Either it can't get at some required information and thus makes wrong decisions, or we mess up some weights/etc. and cause it to make the wrong decisions when RPS init has been done, or the entire thing is just wrong. Would require a bunch of reverse engineering to figure out what's going on.

We are incorrectly limiting the max allocation size as per the mm max_order, which is effectively the largest power-of-two that we can fit in the region size. However, it's normal to setup the region or allocator with a non-power-of-two size(for example 3G), which we should already handle correctly, except it seems for the early too-big-check. v2: make sure we also exercise the I915_BO_ALLOC_CONTIGUOUS path, which is quite different, since for that we are actually limited by the largest power-of-two that we can fit within the region size.

Most of the helpers to retrieve vc4 structures from the DRM base structures rely on the fact that the first member of the vc4 structure is the DRM one and just cast the pointers between them. However, this is pretty fragile especially since there's no check to make sure that the DRM structure is indeed at the offset 0 in the structure, so let's use container_of to make it more robust.

When we forward an mmap to the dma_buf exporter, they get to own everything. Unfortunately drm_gem_mmap_obj() overwrote vma->vm_private_data after the driver callback, wreaking the exporter complete. This was noticed because vb2_common_vm_close blew up on mali gpu with panfrost after commit 26d3ac3c ("drm/shmem-helpers: Redirect mmap for imported dma-buf"). Unfortunately drm_gem_mmap_obj also acquires a surplus reference that we need to drop in shmem helpers, which is a bit of a mislayer situation. Maybe the entire dma_buf_mmap forwarding should be pulled into core gem code. Note that the only two other drivers which forward mmap in their own code (etnaviv and exynos) get this somewhat right by overwriting the gem mmap code. But they seem to still have the leak. This might be a good excuse to move these drivers over to shmem helpers completely. Reviewed-by:

When running the trigger hook, ALSA by default will take a spinlock, and thus will run the trigger hook in atomic context. However, our HDMI driver will send the infoframes as part of the trigger hook, and part of that process is to wait for a bit to be cleared for up to 100ms. To be nicer to the system, that wait has some usleep_range that interact poorly with the atomic context. There's several ways we can fix this, but the more obvious one is to make ALSA take a mutex instead by setting the nonatomic flag on the DAI link. That doesn't work though, since now the cyclic callback installed by the dmaengine helpers in ALSA will take a mutex, while that callback is run by dmaengine's virt-chan code in a tasklet where sleeping is not allowed either. Given the delay we need to poll the bit for, changing the usleep_range for a udelay and keep running it from a context where interrupts are disabled is not really a good option either. However, we can move the infoframe setup code in the hw_params hook, like is usually done in other HDMI controllers, that isn't protected by a spinlock and thus where we can sleep. Infoframes will be sent on a regular basis anyway, and since hw_params is where the audio parameters that end up in the infoframes are setup, this also makes a bit more sense.

ASSERT_CRITICAL() invokes kgdb_breakpoint() whenever either CONFIG_KGDB or CONFIG_HAVE_KGDB is set. This, however, may lead to a kernel panic when no kdb stuff is attached, since the kgdb_breakpoint() call issues INT3. It's nothing but a surprise for normal end-users. For avoiding the pitfall, make the kgdb_breakpoint() call only when CONFIG_DEBUG_KERNEL_DC is set. https://bugzilla.opensuse.org/show_bug.cgi?id=1177973 Cc: <stable@vger.kernel.org> Acked-by:
