2021-11-29drm/i915: Add support for panels with VESA backlights with PWM enable/disableLyude Paul
This simply adds proper support for panel backlights that can be controlled via VESA's backlight control protocol, but which also require that we enable and disable the backlight via PWM instead of via the DPCD interface. We also enable this by default, in order to fix some people's backlights that were broken by not having this enabled. For reference, backlights that require this and use VESA's backlight interface tend to be laptops with hybrid GPUs, but this very well may change in the future. v4: * Make sure that we call intel_backlight_level_to_pwm() in intel_dp_aux_vesa_enable_backlight() - vsyrjala Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://gitlab.freedesktop.org/drm/intel/-/issues/3680 Fixes: fe7d52bccab6 ("drm/i915/dp: Don't use DPCD backlights that need PWM enable/disable") Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: <stable@vger.kernel.org> # v5.12+ Link: https://patchwork.freedesktop.org/patch/msgid/20211105183342.130810-2-lyude@redhat.com (cherry picked from commit 04f0d6cc62cc1eaf9242c081520c024a17ba86a3) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2021-11-29drm/vc4: kms: Fix previous HVS commit waitMaxime Ripard
Our current code is supposed to serialise the commits by waiting for all the drm_crtc_commits associated to the previous HVS state. However, assuming we have two CRTCs running and being configured and we configure each one alternately, we end up in a situation where we're not waiting at all. Indeed, starting with a state (state 0) where both CRTCs are running, and doing a commit (state 1) on the first CRTC (CRTC 0), we'll associate its commit to its assigned FIFO in vc4_hvs_state. If we get a new commit (state 2), this time affecting the second CRTC (CRTC 1), the DRM core will allow both commits to execute in parallel (assuming they don't have any share resources). Our code in vc4_atomic_commit_tail is supposed to make sure we only get one commit at a time and serialised by order of submission. It does so by using for_each_old_crtc_in_state, making sure that the CRTC has a FIFO assigned, is used, and has a commit pending. If it does, then we'll wait for the commit before going forward. During the transition from state 0 to state 1, as our old CRTC state we get the CRTC 0 state 0, its commit, we wait for it, everything works fine. During the transition from state 1 to state 2 though, the use of for_each_old_crtc_in_state is wrong. Indeed, while the code assumes it's returning the state of the CRTC in the old state (so CRTC 0 state 1), it actually returns the old state of the CRTC affected by the current commit, so CRTC 0 state 0 since it wasn't part of state 1. Due to this, if we alternate between the configuration of CRTC 0 and CRTC 1, we never actually wait for anything since we should be waiting on the other every time, but it never is affected by the previous commit. Change the logic to, at every commit, look at every FIFO in the previous HVS state, and if it's in use and has a commit associated to it, wait for that commit.

2021-11-29drm/vc4: kms: Don't duplicate pending commitMaxime Ripard
Our HVS global state, when duplicated, will also copy the pointer to the drm_crtc_commit (and increase the reference count) for each FIFO if the pointer is not NULL. However, our atomic_setup function will overwrite that pointer without putting the reference back leading to a memory leak. Since the commit is only relevant during the atomic commit process, it doesn't make sense to duplicate the reference to the commit anyway. Let's remove it.

Commit 9ec03d7f1ed3 ("drm/vc4: kms: Wait on previous FIFO users before a commit") introduced a wait on the previous commit done on a given HVS FIFO. However, we never cleared that pointer once done. Since drm_crtc_commit_put can free the drm_crtc_commit structure directly if we were the last user, this means that it can lead to a use-after free if we were to duplicate the state, and that stale pointer would even be copied to the new state. Set the pointer to NULL once we're done with the wait so that we don't carry over a pointer to a free'd structure.

2021-11-29drm/vc4: kms: Wait for the commit before increasing our clock rateMaxime Ripard
Several DRM/KMS atomic commits can run in parallel if they affect different CRTC. These commits share the global HVS state, so we have some code to make sure we run commits in sequence. This synchronization code is one of the first thing that runs in vc4_atomic_commit_tail(). Another constraints we have is that we need to make sure the HVS clock gets a boost during the commit. That code relies on clk_set_min_rate and will remove the old minimum and set a new one. We also need another, temporary, minimum for the duration of the commit. The algorithm is thus to set a temporary minimum, drop the previous one, do the commit, and finally set the minimum for the current mode. However, the part that sets the temporary minimum and drops the older one runs before the commit synchronization code. Thus, under the proper conditions, we can end up mixing up the minimums and ending up with the wrong one for our current step. To avoid it, let's move the clock setup in the protected section.

The driver assumes that split headers can be enabled/disabled without stopping/starting the device, so it writes DMA_CHAN_CONTROL from stmmac_set_features(). However, on my system (IP v5.10a without Split Header support), simply writing DMA_CHAN_CONTROL when DMA is running (for example, with the commands below) leads to a TX watchdog timeout. host$ socat TCP-LISTEN:1024,fork,reuseaddr - & device$ ethtool -K eth0 tso off device$ ethtool -K eth0 tso on device$ dd if=/dev/zero bs=1M count=10 | socat - TCP4:host:1024 <tx watchdog timeout> Note that since my IP is configured without Split Header support, the driver always just reads and writes the same value to the DMA_CHAN_CONTROL register. I don't have access to any platforms with Split Header support so I don't know if these writes to the DMA_CHAN_CONTROL while DMA is running actually work properly on such systems. I could not find anything in the databook that says that DMA_CHAN_CONTROL should not be written when the DMA is running. But on systems without Split Header support, there is in any case no need to call enable_sph() in stmmac_set_features() at all since SPH can never be toggled, so we can avoid the watchdog timeout there by skipping this call.

2021-11-26iommu/vt-d: Fix unmap_pages supportAlex Williamson
When supporting only the .map and .unmap callbacks of iommu_ops, the IOMMU driver can make assumptions about the size and alignment used for mappings based on the driver provided pgsize_bitmap. VT-d previously used essentially PAGE_MASK for this bitmap as any power of two mapping was acceptably filled by native page sizes. However, with the .map_pages and .unmap_pages interface we're now getting page-size and count arguments. If we simply combine these as (page-size * count) and make use of the previous map/unmap functions internally, any size and alignment assumptions are very different. As an example, a given vfio device assignment VM will often create a 4MB mapping at IOVA pfn [0x3fe00 - 0x401ff]. On a system that does not support IOMMU super pages, the unmap_pages interface will ask to unmap 1024 4KB pages at the base IOVA. dma_pte_clear_level() will recurse down to level 2 of the page table where the first half of the pfn range exactly matches the entire pte level. We clear the pte, increment the pfn by the level size, but (oops) the next pte is on a new page, so we exit the loop an pop back up a level. When we then update the pfn based on that higher level, we seem to assume that the previous pfn value was at the start of the level. In this case the level size is 256K pfns, which we add to the base pfn and get a results of 0x7fe00, which is clearly greater than 0x401ff, so we're done. Meanwhile we never cleared the ptes for the remainder of the range. When the VM remaps this range, we're overwriting valid ptes and the VT-d driver complains loudly, as reported by the user report linked below. The fix for this seems relatively simple, if each iteration of the loop in dma_pte_clear_level() is assumed to clear to the end of the level pte page, then our next pfn should be calculated from level_pfn rather than our working pfn.

2021-11-26net: dsa: microchip: implement multi-bridge supportOleksij Rempel
Current driver version is able to handle only one bridge at time. Configuring two bridges on two different ports would end up shorting this bridges by HW. To reproduce it: ip l a name br0 type bridge ip l a name br1 type bridge ip l s dev br0 up ip l s dev br1 up ip l s lan1 master br0 ip l s dev lan1 up ip l s lan2 master br1 ip l s dev lan2 up Ping on lan1 and get response on lan2, which should not happen. This happened, because current driver version is storing one global "Port VLAN Membership" and applying it to all ports which are members of any bridge. To solve this issue, we need to handle each port separately. This patch is dropping the global port member storage and calculating membership dynamically depending on STP state and bridge participation. Note: STP support was broken before this patch and should be fixed separately.
