On ARM PCI systems, the PCI hierarchy might be reconfigured during boot and the firmware framebuffer might move as a result of that. The values in screen_info will then be invalid. Work around this problem by tracking the framebuffer's initial location before it get relocated; then fix the screen_info state between reloaction and creating the firmware framebuffer's device. This functionality has been lifted from efifb. See the commit message of commit 55d728a4 ("efi/fb: Avoid reconfiguration of BAR that covers the framebuffer") for more information. Signed-off-by:

There will be no EFI framebuffer device for disabled parent devices and thus we never probe efifb in that case. Hence remove the tracking code from efifb. Signed-off-by:

Test if the firmware framebuffer's parent PCI device, if any, has been enabled. If not, the firmware framebuffer is most likely not working. Hence, do not create a device for the firmware framebuffer on disabled PCI devices. So far, efifb tracked the status of the PCI parent device internally and did not bind if it was disabled. This patch implements the functionality for all PCI-based firmware framebuffers. v3: * make commit message more precise (Sui) v2: * rework sysfb_pci_dev_is_enabled() (Javier) Signed-off-by:

Set the firmware framebuffer's parent device, which usually is the graphics hardware's physical device. Integrates the framebuffer in the Linux device hierarchy and lets Linux handle dependencies among devices. For example, the graphics hardware won't be suspended while the firmware device is still active. v4: * fix build for CONFIG_SYSFB_SIMPLEFB=n, again v3: * fix build for CONFIG_SYSFB_SIMPLEFB=n (Sui) * test result of screen_info_pci_dev() for errors (Sui) v2: * detect parent device in sysfb_parent_dev() Signed-off-by:

The plain values as stored in struct screen_info need to be decoded before being used. Add helpers that decode the type of video output and the framebuffer I/O aperture. Old or non-x86 systems may not set the type of video directly, but only indicate the presence by storing 0x01 in orig_video_isVGA. The decoding logic in screen_info_video_type() takes this into account. It then follows similar code in vgacon's vgacon_startup() to detect the video type from the given values. A call to screen_info_resources() returns all known resources of the given screen_info. The resources' values have been taken from existing code in vgacon and vga16fb. These drivers can later be converted to use the new interfaces. v2: * return ssize_t from screen_info_resources() * don't call __screen_info_has_lfb() unnecessarily Signed-off-by:

The hdmi-connector nodes are now functional and the new way to model hdmi ports nodes with both in and output port subnodes. Unfortunately with the conversion to YAML the old method with only an input port node was used. Later the new method was also added to the binding. A binding must be unambiguously, so remove the old port property entirely and make port@0 and port@1 a requirement as all upstream dts files are updated as well and because checking deprecated stuff is a bit pointless. Update the example to avoid use of the removed property. Signed-off-by:

Since commit d492cc25 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the host1x_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

The previous 500ms default timeout was fairly optimistic and could be hit by real world applications. Many distributions targeting devices with a Mali-4xx already bumped this timeout to a higher limit. We can be generous here with a high value as 10s since this should mostly catch buggy jobs like infinite loop shaders, and these don't seem to happen very often in real applications. Signed-off-by:

Marking the context as guilty currently only makes the application which hits a single timeout problem to stop its rendering context entirely. All jobs submitted later are dropped from the guilty context. Lima runs on fairly underpowered hardware for modern standards and it is not entirely unreasonable that a rendering job may time out occasionally due to high system load or too demanding application stack. In this case it would be generally preferred to report the error but try to keep the application going. Other similar embedded GPU drivers don't make use of the guilty context flag. Now that there are reliability improvements to the lima timeout recovery handling, drop the guilty contexts to let the application keep running in this case. Signed-off-by:

There are several unexplained and unreproduced cases of rendering timeouts with lima, for which one theory is high IRQ latency coming from somewhere else in the system. This kind of occurrence may cause applications to trigger unnecessary resets of the GPU or even applications to hang if it hits an issue in the recovery path. Panfrost already does some special handling to account for such "spurious timeouts", it makes sense to have this in lima too to reduce the chance that it hit users. Signed-off-by:

This is required for reliable hard resets. Otherwise, doing a hard reset while a task is still running (such as a task which is being stopped by the drm_sched timeout handler) may result in random mmu write timeouts or lockups which cause the entire gpu to hang. Signed-off-by:

Lima gp jobs use an async reset to avoid having to wait for the soft reset right after a job. The soft reset is done at the end of a job and a reset_complete flag is expected to be set at the next job. However, in case the user runs into a job timeout from any application, a hard reset is issued to the hardware. This hard reset clears the reset_complete flag, which causes an error message to show up before the next job. This is probably harmless for the execution but can be very confusing to debug, as it blames a reset timeout on the next application to submit a job. Reset the async_reset flag when doing the hard reset so that we don't get that message. Signed-off-by:
