2024-02-01drm/tegra: Do not assume that a NULL domain means no DMA IOMMUJason Gunthorpe1-1/+2
Previously with tegra-smmu, even with CONFIG_IOMMU_DMA, the default domain could have been left as NULL. The NULL domain is specially recognized by host1x_client_iommu_attach() as meaning it is not the DMA domain and should be replaced with the special shared domain. This happened prior to the below commit because tegra-smmu was using the NULL domain to mean IDENTITY. Now that the domain is properly labled the test in DRM doesn't see NULL. Check for IDENTITY as well to enable the special domains.

2023-07-27drm/tegra: Enable runtime PM during probeMikko Perttunen4-38/+28
Currently, engine drivers only enable runtime PM during the host1x init callback. This can happen slightly later than the probe, which can cause the power domain to intermittently not be turned off after probe. My hypothesis is that there is a race condition between the post-probe power domain poweroff that is done from a queued work, and the pm_runtime_enable call happening in the host1x init callback. If the pm_runtime_enable call happens first, everything is OK and the power off work can disable the power domain as PM runtime is enabled and the device is runtime suspended. If power off work runs first, PM runtime is still disabled for the device and the domain must be kept powered. Resolve the issue by moving the runtime PM enablement to the probe function.

2023-07-11drm/client: Send hotplug event after registering a clientThomas Zimmermann1-4/+0
Generate a hotplug event after registering a client to allow the client to configure its display. Remove the hotplug calls from the existing clients for fbdev emulation. This change fixes a concurrency bug between registering a client and receiving events from the DRM core. The bug is present in the fbdev emulation of all drivers. The fbdev emulation currently generates a hotplug event before registering the client to the device. For each new output, the DRM core sends an additional hotplug event to each registered client. If the DRM core detects first output between sending the artificial hotplug and registering the device, the output's hotplug event gets lost. If this is the first output, the fbdev console display remains dark. This has been observed with amdgpu and fbdev-generic. Fix this by adding hotplug generation directly to the client's register helper drm_client_register(). Registering the client and receiving events are serialized by struct drm_device.clientlist_mutex. So an output is either configured by the initial hotplug event, or the client has already been registered. The bug was originally added in commit 6e3f17ee73f7 ("drm/fb-helper: generic: Call drm_client_add() after setup is done"), in which adding a client and receiving a hotplug event switched order. It was hidden, as most hardware and drivers have at least on static output configured. Other drivers didn't use the internal DRM client or still had struct drm_mode_config_funcs.output_poll_changed set. That callback handled hotplug events as well. After not setting the callback in amdgpu in commit 0e3172bac3f4 ("drm/amdgpu: Don't set struct drm_driver.output_poll_changed"), amdgpu did not show a framebuffer console if output events got lost. The bug got copy-pasted from fbdev-generic into the other fbdev emulation.

2023-06-09drm/tegra: sor: Add a determine_rate hookMaxime Ripard1-0/+1
The Tegra sor pad clock implements a mux with a set_parent hook, but doesn't provide a determine_rate implementation. This is a bit odd, since set_parent() is there to, as its name implies, change the parent of a clock. However, the most likely candidates to trigger that parent change are either the assigned-clock-parents device tree property or a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate. The other trigger would be a call to clk_set_parent(), but it's far less used, and it doesn't look like there's any obvious user for that clock. Similarly, it doesn't look like the device tree using that clock driver uses any of the assigned-clock properties on that clock. So, the set_parent hook is effectively unused, possibly because of an oversight. However, it could also be an explicit decision by the original author to avoid any reparenting but through an explicit call to clk_set_parent(). The latter case would be equivalent to setting the determine_rate implementation to clk_hw_determine_rate_no_reparent(). Indeed, if no determine_rate implementation is provided, clk_round_rate() (through clk_core_round_rate_nolock()) will call itself on the parent if CLK_SET_RATE_PARENT is set, and will not change the clock rate otherwise. And if it was an oversight, then we are at least explicit about our behavior now and it can be further refined down the line.

2023-06-01drm/tegra: Use regular fbdev I/O helpersThomas Zimmermann2-5/+4
Use the regular fbdev helpers for framebuffer I/O instead of DRM's helpers. Tegra does not use damage handling, so DRM's fbdev helpers are mere wrappers around the fbdev code. By using fbdev helpers directly within each DRM fbdev emulation, we can eventually remove DRM's wrapper functions entirely. v4: * use initializer macros for struct fb_ops v2: * use FB_SYS_HELPERS option Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Mikko Perttunen <mperttunen@nvidia.com> Cc: Jonathan Hunter <jonathanh@nvidia.com> Acked-by: Thierry Reding <treding@nvidia.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230530151228.22979-10-tzimmermann@suse.de

2023-04-16drm/aperture: Remove primary argumentDaniel Vetter1-1/+1
Only really pci devices have a business setting this - it's for figuring out whether the legacy vga stuff should be nuked too. And with the preceding two patches those are all using the pci version of this. Which means for all other callers primary == false and we can remove it now. v2: - Reorder to avoid compile fail (Thomas) - Include gma500, which retained it's called to the non-pci version. v4: - fix Daniel's S-o-b address v5: - add back an S-o-b tag with Daniel's Intel address Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Deepak Rawat <drawat.floss@gmail.com> Cc: Neil Armstrong <neil.armstrong@linaro.org> Cc: Kevin Hilman <khilman@baylibre.com> Cc: Jerome Brunet <jbrunet@baylibre.com> Cc: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Jonathan Hunter <jonathanh@nvidia.com> Cc: Emma Anholt <emma@anholt.net> Cc: Helge Deller <deller@gmx.de> Cc: David Airlie <airlied@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: linux-hyperv@vger.kernel.org Cc: linux-amlogic@lists.infradead.org Cc: linux-arm-kernel@lists.infradead.org Cc: linux-tegra@vger.kernel.org Cc: linux-fbdev@vger.kernel.org Acked-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Acked-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230406132109.32050-4-tzimmermann@suse.de

https://gitlab.freedesktop.org/drm/tegra into drm-next drm/tegra: Changes for v6.4-rc1 The majority of this is minor cleanups and fixes. Other than those, this contains Uwe's conversion to the new driver remove callback and Thomas' fbdev DRM client conversion. The driver can now also be built on other architectures to easy compile coverage. Finally, this adds Mikko as a second maintainer for the driver. As a next step we also want Tegra DRM to move into drm-misc to streamline the maintenance process.

2023-04-06drm/tegra: Avoid potential 32-bit integer overflowNur Hussein1-1/+1
In tegra_sor_compute_config(), the 32-bit value mode->clock is multiplied by 1000, and assigned to the u64 variable pclk. We can avoid a potential 32-bit integer overflow by casting mode->clock to u64 before we do the arithmetic and assignment.

2023-04-06drm/tegra: Implement fbdev emulation as in-kernel clientThomas Zimmermann3-132/+86
Move code from ad-hoc fbdev callbacks into DRM client functions and remove the old callbacks. The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality. Replace all code that initializes or releases fbdev emulation throughout the driver. Instead initialize the fbdev client by a single call to tegra_fbdev_setup() after tegra has registered its DRM device. As in most drivers, tegra's fbdev emulation now acts like a regular DRM client. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_dev_unregister() releases the client automatically. No further action is required within tegra. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup.
