2024-11-04drm/nouveau: Add drm_panic support for nv50+Jocelyn Falempe
Add drm_panic support for nv50+ cards. It's enough to get the panic screen while running Gnome/Wayland with an nv50+ nvidia GPU. It doesn't support multi-plane or compressed format yet. Tiling is tested on GTX1650 (Turing), GeForce GT 1030 (Pascal) and Geforce 8800 GTS (Tesla).

They are, however, only used on timeout handling (reset recovery). The docstrings should reflect that to prevent confusion. Document those functions' purpose.

2024-10-31drm/panel: samsung-s6e88a0-ams427ap24: Add flip optionJakob Hauser
The way of implementing a flip option follows the existing panel-samsung-s6e8aa0.c [1][2][3]. The value to flip the screen is taken from a downstream kernel file of a similar but older panel [4]. The mipi clock [5] for the new panel samsung-s6e88a0-ams427ap24 matches 461 MHz and a hardware read-out of the 0xcb values corresponds to revision R01 of that older panel [6]. Although for samsung-s6e88a0-ams427ap24 that's in non-flipped state while in this older driver it seems to be the other way around. Further up there is a hint [7] basically saying for revision R01 to change the first word of the 0xcb command from 0x06 to 0x0e, which is actually setting BIT(3) of that word. This causes a horizontal flip.

2024-10-31drm/panel: samsung-s6e88a0-ams427ap24: Add brightness controlJakob Hauser
The tables for brightness to candela, aid and elvss were taken from downstream kernel file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [1][2][3]. The gamma table gets generated in "ss_dsi_smart_dimming_S6E88A0_AMS427AP24.c" [4] with hard-coded starting values. The function smart_dimming_init() [5] goes through the v{*}_adjustments, generate_gray_scale and gamma_init procedure. Instead of calculating it manually, it's easier to compile a custom downstream kernel with SMART_DIMMING_DEBUG enabled and read out dmesg early at boot. Selection of the values for aid and elvss are again according to downstream file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [6][7]. The set of write commands is guided by downstream file "ss_dsi_panel_common.c" [8] followed by "ss_dsi_panel_S6E88A0_AMS427AP24.c" [9]. The dsi mode flag MIPI_DSI_MODE_VIDEO_NO_HFP prevents screen flickering while changing the brightness.

2024-10-31drm/panel: samsung-s6e88a0-ams427ap24: Add initial driverJakob Hauser
This initial part of the panel driver was mostly generated by the "linux-mdss-dsi-panel-driver-generator" tool [1], reading downstream Android kernel file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [2]. On top of the generic output of the tool, there were a couple of changes applied: - Added mipi_dsi_dcs_set_display_on() to function s6e88a0_ams427ap24_on(), otherwise the display does not show up. - In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off() changed DSI commands to multi context and used "accum_err" returns. - In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off() replaced msleep() by mipi_dsi_msleep(). - The function s6e88a0_ams427ap24_get_modes() was changed to make use of drm_connector_helper_get_modes_fixed(). This also required to include drm/drm_probe_helper.h. - In function s6e88a0_ams427ap24_probe() registring the regulators was changed to devm_regulator_bulk_get_const(). This required to change supplies in struct s6e88a0_ams427ap24 to a pointer. - Removed bool "prepared" from struct s6e88a0_ams427ap24 and according parts in functions s6e88a0_ams427ap24_prepare() and s6e88a0_ams427ap24_unprepare(). - Removed include <linux/of.h>, it's not needed. - Added comments to the mipi_dsi_dcs_write_seq_multi() lines in function s6e88a0_ams427ap24_on().

2024-10-30drm: zynqmp_dp: Add lockingSean Anderson
Add some locking to prevent the IRQ/workers/bridge API calls from stepping on each other's toes. This lock protects: - Non-atomic registers configuring the link. That is, everything but the IRQ registers (since these are accessed in an atomic fashion), and the DP AUX registers (since these don't affect the link). We also access AUX while holding this lock, so it would be very tricky to support. - Link configuration. This is effectively everything in zynqmp_dp which isn't read-only after probe time. So from next_bridge onward. This lock is designed to protect configuration changes so we don't have to do anything tricky. Configuration should never be in the hot path, so I'm not worried about performance.

2024-10-30accel/ivpu: Defer MMU root page table allocationKarol Wachowski
Defer root page table allocation and unify context init/fini functions. Move allocation of the root page table from the file_priv_open function to perform a lazy allocation approach during ivpu_bo_pin(). By doing so, we avoid the overhead of allocating page tables for simple operations like GET_PARAM that do not require them. Additionally, the MMU context descriptor table initialization has been moved to the ivpu_mmu_context_map_page function. This change streamlines the process and ensures that the descriptor table is only initialized when it is actually needed. Refactor init/fini functions to remove redundant code and make the context management more straightforward. Overall, these changes lead to a reduction in the time taken by the file descriptor open operation, as the costly root page table allocation is now avoided for operations that do not require it.

2024-10-25accel/qaic: Add crashdump to SaharaJeffrey Hugo
The Sahara protocol has a crashdump functionality. In the hello exchange, the device can advertise it has a memory dump available for the host to collect. Instead of the device making requests of the host, the host requests data from the device which can be later analyzed. Implement this functionality and utilize the devcoredump framework for handing the dump over to userspace. Similar to how firmware loading in Sahara involves multiple files, crashdump can consist of multiple files for different parts of the dump. Structure these into a single buffer that userspace can parse and extract the original files from.
