If we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl() we proceed to unref the fb and then retry the whole thing from the top. But we forget to reset the fb pointer back to NULL, and so if we then get another error during the retry, before the fb lookup, we proceed the unref the same fb again without having gotten another reference. The end result is that the fb will (eventually) end up being freed while it's still in use. Reset fb to NULL once we've unreffed it to avoid doing it again until we've done another fb lookup. This turned out to be pretty easy to hit on a DG2 when doing async flips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom I saw that drm_closefb() simply got stuck in a busy loop while walking the framebuffer list. Fortunately I was able to convince it to oops instead, and from there it was easier to track down the culprit. Cc: stable@vger.kernel.org Signed-off-by:

The aux-bridge and aux-hpd-bridge drivers didn't call of_node_get() on the device nodes further used for dev->of_node and platform data. When bridge devices are released, the reference counts are decreased, resulting in refcount underflow / use-after-free warnings. Get corresponding refcounts during AUX bridge allocation. Reported-by:

It is possible to double free the vm_ctx->mmu_ctx object in this function. 630 err_page_table_destroy: --> 631 pvr_mmu_context_destroy(vm_ctx->mmu_ctx); The pvr_vm_context_put() function does: kref_put(&vm_ctx->ref_count, pvr_vm_context_release); Here the pvr_vm_context_release() will call: pvr_mmu_context_destroy(vm_ctx->mmu_ctx); Refactor to an unwind style.

While writing the matching IGT suite I discovered that it's possible to cause a kernel oops when using DRM_IOCTL_PVR_CREATE_HWRT_DATASET when the call to hwrt_init_common_fw_structure() fails. Use an unwind-type error path to avoid cleaning up the object using the the release function before it is fully resolved. Signed-off-by:

Unwinding loop in error path for this function uses unsigned limit variable, causing the promotion of the signed counter variable. --> 204 for (; pfn >= start_pfn; pfn--) ^^^^^^^^^^^^^^^^ If start_pfn can be zero then this is an endless loop. I've seen this code in other places as well. This loop is slightly off as well. It should decrement pfn on the first iteration. Fix by making the loop limit variables signed. Also fix missing predecrement by modifying to while loop. Reported-by:

Mediatek 8173 and 8183 SOCs have a separate display controller and GPU with different drivers for each. For mt8173, the GPU driver is powervr and the display driver is mediatek. In the case of mt8183, the GPU driver is panfrost and the display driver is mediatek. Setting IGT_FORCE_DRIVER to panfrost for mt8173 is not the expected driver. So set mediatek for mt8173. Support to test both GPU and display drivers for these ARM SOCs will be added in the next patch series to increase test coverage. Acked-by:

When conditionally checking for heap existence of a certian address in pvr_vm_bind_op_map_init the condition whether the map request comes from a user is incorrect: The context must not be the kernel-context to be a user(space) context and should be looked up in pvr_heaps. That makes addresses coming from userspace not being verfied against the defined ranges and prevents firmware loading for meta cores.

Even though we were rolling our own custom state for the vc4 HDMI controller driver, we were still using the generic helper to destroy that state. It was mostly working since the underlying state is the first member of our state so the pointers are probably equal in all relevant cases, but it's still fragile so let's fix this properly.

This reverts commit b63a553e. regcache_sync will try to reload the configuration in regcache to hardware, but the registers of 4 Cluster windows and Esmart1/2/3 on the upcoming rk3588 can not be set successfully before internal PD power on. Also it's better to keep the hardware register as it is before we really enable it.

It's the ti_sn65dsi86.pwm auxiliary driver that creates the pwmchip, so let the auxiliary device be the parent of the pwm device. Note that getting a reference to the ti-sn65dsi86's pwm using pwm_get() isn't affected by this change as ti_sn65dsi86_add_aux_device() sets the auxiliary device's of_node to that of the main device. Also change PM runtime tracking and diagnostic messages to use that one. After enabling runtime PM operation for the auxiliary device, all works as expected as parent devices are handled just fine.
