2024-06-10ACPI: utils: introduce acpi_get_local_u64_address()Pierre-Louis Bossart
The ACPI _ADR is a 64-bit value. We changed the definitions in commit ca6f998cf9a2 ("ACPI: bus: change _ADR representation to 64 bits") but some helpers still assume the value is a 32-bit value. This patch adds a new helper to extract the full 64-bits. The existing 32-bit helper is kept for backwards-compatibility and cases where the _ADR is known to fit in a 32-bit value.

2024-06-10drm/bridge/panel: Fix runtime warning on panel bridge releaseAdam Miotk
Device managed panel bridge wrappers are created by calling to drm_panel_bridge_add_typed() and registering a release handler for clean-up when the device gets unbound. Since the memory for this bridge is also managed and linked to the panel device, the release function should not try to free that memory. Moreover, the call to devm_kfree() inside drm_panel_bridge_remove() will fail in this case and emit a warning because the panel bridge resource is no longer on the device resources list (it has been removed from there before the call to release handlers).

2024-06-10ARM: 9404/1: arm32: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATIONYuntao Liu
The current arm32 architecture does not yet support the HAVE_LD_DEAD_CODE_DATA_ELIMINATION feature. arm32 is widely used in embedded scenarios, and enabling this feature would be beneficial for reducing the size of the kernel image. In order to make this work, we keep the necessary tables by annotating them with KEEP, also it requires further changes to linker script to KEEP some tables and wildcard compiler generated sections into the right place. When using ld.lld for linking, KEEP is not recognized within the OVERLAY command, and Ard proposed a concise method to solve this problem. It boots normally with defconfig, vexpress_defconfig and tinyconfig. The size comparison of zImage is as follows: defconfig vexpress_defconfig tinyconfig 5137712 5138024 424192 no dce 5032560 4997824 298384 dce 2.0% 2.7% 29.7% shrink When using smaller config file, there is a significant reduction in the size of the zImage. We also tested this patch on a commercially available single-board computer, and the comparison is as follows: a15eb_config 2161384 no dce 2092240 dce 3.2% shrink The zImage size has been reduced by approximately 3.2%, which is 70KB on 2.1M.

2024-06-10drm/sun4i: Fix layer zpos change/atomic modesettingOndrej Jirman
Identical configurations of planes can lead to different (and wrong) layer -> pipe routing at HW level, depending on the order of atomic plane changes. For example: - Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer is enabled. This is a typical situation at boot. - When a compositor takes over and layer 3 is enabled, sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which will lead to incorrect disabling of pipe 0 and enabling of pipe 1. What happens is that sun8i_ui_layer_enable() function may disable blender pipes even if it is no longer assigned to its layer. To correct this, move the routing setup out of individual plane's atomic_update into crtc's atomic_update, where it can be calculated and updated all at once. Remove the atomic_disable callback because it is no longer needed.

2024-06-10mlxsw: spectrum_acl: Fix ACL scale regression and firmware errorsIdo Schimmel
ACLs that reside in the algorithmic TCAM (A-TCAM) in Spectrum-2 and newer ASICs can share the same mask if their masks only differ in up to 8 consecutive bits. For example, consider the following filters: # tc filter add dev swp1 ingress pref 1 proto ip flower dst_ip 192.0.2.0/24 action drop # tc filter add dev swp1 ingress pref 1 proto ip flower dst_ip 198.51.100.128/25 action drop The second filter can use the same mask as the first (dst_ip/24) with a delta of 1 bit. However, the above only works because the two filters have different values in the common unmasked part (dst_ip/24). When entries have the same value in the common unmasked part they create undesired collisions in the device since many entries now have the same key. This leads to firmware errors such as [1] and to a reduced scale. Fix by adjusting the hash table key to only include the value in the common unmasked part. That is, without including the delta bits. That way the driver will detect the collision during filter insertion and spill the filter into the circuit TCAM (C-TCAM). Add a test case that fails without the fix and adjust existing cases that check C-TCAM spillage according to the above limitation.

2024-06-10mlxsw: spectrum_acl_erp: Fix object nesting warningIdo Schimmel
ACLs in Spectrum-2 and newer ASICs can reside in the algorithmic TCAM (A-TCAM) or in the ordinary circuit TCAM (C-TCAM). The former can contain more ACLs (i.e., tc filters), but the number of masks in each region (i.e., tc chain) is limited. In order to mitigate the effects of the above limitation, the device allows filters to share a single mask if their masks only differ in up to 8 consecutive bits. For example, dst_ip/25 can be represented using dst_ip/24 with a delta of 1 bit. The C-TCAM does not have a limit on the number of masks being used (and therefore does not support mask aggregation), but can contain a limited number of filters. The driver uses the "objagg" library to perform the mask aggregation by passing it objects that consist of the filter's mask and whether the filter is to be inserted into the A-TCAM or the C-TCAM since filters in different TCAMs cannot share a mask. The set of created objects is dependent on the insertion order of the filters and is not necessarily optimal. Therefore, the driver will periodically ask the library to compute a more optimal set ("hints") by looking at all the existing objects. When the library asks the driver whether two objects can be aggregated the driver only compares the provided masks and ignores the A-TCAM / C-TCAM indication. This is the right thing to do since the goal is to move as many filters as possible to the A-TCAM. The driver also forbids two identical masks from being aggregated since this can only happen if one was intentionally put in the C-TCAM to avoid a conflict in the A-TCAM. The above can result in the following set of hints: H1: {mask X, A-TCAM} -> H2: {mask Y, A-TCAM} // X is Y + delta H3: {mask Y, C-TCAM} -> H4: {mask Z, A-TCAM} // Y is Z + delta After getting the hints from the library the driver will start migrating filters from one region to another while consulting the computed hints and instructing the device to perform a lookup in both regions during the transition. Assuming a filter with mask X is being migrated into the A-TCAM in the new region, the hints lookup will return H1. Since H2 is the parent of H1, the library will try to find the object associated with it and create it if necessary in which case another hints lookup (recursive) will be performed. This hints lookup for {mask Y, A-TCAM} will either return H2 or H3 since the driver passes the library an object comparison function that ignores the A-TCAM / C-TCAM indication. This can eventually lead to nested objects which are not supported by the library [1]. Fix by removing the object comparison function from both the driver and the library as the driver was the only user. That way the lookup will only return exact matches. I do not have a reliable reproducer that can reproduce the issue in a timely manner, but before the fix the issue would reproduce in several minutes and with the fix it does not reproduce in over an hour. Note that the current usefulness of the hints is limited because they include the C-TCAM indication and represent aggregation that cannot actually happen. This will be addressed in net-next.

2024-06-10drm/exynos: hdmi: report safe 640x480 mode as a fallback when no EDID foundMarek Szyprowski
When reading EDID fails and driver reports no modes available, the DRM core adds an artificial 1024x786 mode to the connector. Unfortunately some variants of the Exynos HDMI (like the one in Exynos4 SoCs) are not able to drive such mode, so report a safe 640x480 mode instead of nothing in case of the EDID reading failure. This fixes the following issue observed on Trats2 board since commit 13d5b040363c ("drm/exynos: do not return negative values from .get_modes()"): [drm] Exynos DRM: using 11c00000.fimd device for DMA mapping operations exynos-drm exynos-drm: bound 11c00000.fimd (ops fimd_component_ops) exynos-drm exynos-drm: bound 12c10000.mixer (ops mixer_component_ops) exynos-dsi 11c80000.dsi: [drm:samsung_dsim_host_attach] Attached s6e8aa0 device (lanes:4 bpp:24 mode-flags:0x10b) exynos-drm exynos-drm: bound 11c80000.dsi (ops exynos_dsi_component_ops) exynos-drm exynos-drm: bound 12d00000.hdmi (ops hdmi_component_ops) [drm] Initialized exynos 1.1.0 20180330 for exynos-drm on minor 1 exynos-hdmi 12d00000.hdmi: [drm:hdmiphy_enable.part.0] *ERROR* PLL could not reach steady state panel-samsung-s6e8aa0 11c80000.dsi.0: ID: 0xa2, 0x20, 0x8c exynos-mixer 12c10000.mixer: timeout waiting for VSYNC ------------[ cut here ]------------ WARNING: CPU: 1 PID: 11 at drivers/gpu/drm/drm_atomic_helper.c:1682 drm_atomic_helper_wait_for_vblanks.part.0+0x2b0/0x2b8 [CRTC:70:crtc-1] vblank wait timed out Modules linked in: CPU: 1 PID: 11 Comm: kworker/u16:0 Not tainted 6.9.0-rc5-next-20240424 #14913 Hardware name: Samsung Exynos (Flattened Device Tree) Workqueue: events_unbound deferred_probe_work_func Call trace: unwind_backtrace from show_stack+0x10/0x14 show_stack from dump_stack_lvl+0x68/0x88 dump_stack_lvl from __warn+0x7c/0x1c4 __warn from warn_slowpath_fmt+0x11c/0x1a8 warn_slowpath_fmt from drm_atomic_helper_wait_for_vblanks.part.0+0x2b0/0x2b8 drm_atomic_helper_wait_for_vblanks.part.0 from drm_atomic_helper_commit_tail_rpm+0x7c/0x8c drm_atomic_helper_commit_tail_rpm from commit_tail+0x9c/0x184 commit_tail from drm_atomic_helper_commit+0x168/0x190 drm_atomic_helper_commit from drm_atomic_commit+0xb4/0xe0 drm_atomic_commit from drm_client_modeset_commit_atomic+0x23c/0x27c drm_client_modeset_commit_atomic from drm_client_modeset_commit_locked+0x60/0x1cc drm_client_modeset_commit_locked from drm_client_modeset_commit+0x24/0x40 drm_client_modeset_commit from __drm_fb_helper_restore_fbdev_mode_unlocked+0x9c/0xc4 __drm_fb_helper_restore_fbdev_mode_unlocked from drm_fb_helper_set_par+0x2c/0x3c drm_fb_helper_set_par from fbcon_init+0x3d8/0x550 fbcon_init from visual_init+0xc0/0x108 visual_init from do_bind_con_driver+0x1b8/0x3a4 do_bind_con_driver from do_take_over_console+0x140/0x1ec do_take_over_console from do_fbcon_takeover+0x70/0xd0 do_fbcon_takeover from fbcon_fb_registered+0x19c/0x1ac fbcon_fb_registered from register_framebuffer+0x190/0x21c register_framebuffer from __drm_fb_helper_initial_config_and_unlock+0x350/0x574 __drm_fb_helper_initial_config_and_unlock from exynos_drm_fbdev_client_hotplug+0x6c/0xb0 exynos_drm_fbdev_client_hotplug from drm_client_register+0x58/0x94 drm_client_register from exynos_drm_bind+0x160/0x190 exynos_drm_bind from try_to_bring_up_aggregate_device+0x200/0x2d8 try_to_bring_up_aggregate_device from __component_add+0xb0/0x170 __component_add from mixer_probe+0x74/0xcc mixer_probe from platform_probe+0x5c/0xb8 platform_probe from really_probe+0xe0/0x3d8 really_probe from __driver_probe_device+0x9c/0x1e4 __driver_probe_device from driver_probe_device+0x30/0xc0 driver_probe_device from __device_attach_driver+0xa8/0x120 __device_attach_driver from bus_for_each_drv+0x80/0xcc bus_for_each_drv from __device_attach+0xac/0x1fc __device_attach from bus_probe_device+0x8c/0x90 bus_probe_device from deferred_probe_work_func+0x98/0xe0 deferred_probe_work_func from process_one_work+0x240/0x6d0 process_one_work from worker_thread+0x1a0/0x3f4 worker_thread from kthread+0x104/0x138 kthread from ret_from_fork+0x14/0x28 Exception stack(0xf0895fb0 to 0xf0895ff8) ... irq event stamp: 82357 hardirqs last enabled at (82363): [<c01a96e8>] vprintk_emit+0x308/0x33c hardirqs last disabled at (82368): [<c01a969c>] vprintk_emit+0x2bc/0x33c softirqs last enabled at (81614): [<c0101644>] __do_softirq+0x320/0x500 softirqs last disabled at (81609): [<c012dfe0>] __irq_exit_rcu+0x130/0x184 ---[ end trace 0000000000000000 ]--- exynos-drm exynos-drm: [drm] *ERROR* flip_done timed out exynos-drm exynos-drm: [drm] *ERROR* [CRTC:70:crtc-1] commit wait timed out exynos-drm exynos-drm: [drm] *ERROR* flip_done timed out exynos-drm exynos-drm: [drm] *ERROR* [CONNECTOR:74:HDMI-A-1] commit wait timed out exynos-drm exynos-drm: [drm] *ERROR* flip_done timed out exynos-drm exynos-drm: [drm] *ERROR* [PLANE:56:plane-5] commit wait timed out exynos-mixer 12c10000.mixer: timeout waiting for VSYNC Cc: stable@vger.kernel.org Fixes: 13d5b040363c ("drm/exynos: do not return negative values from .get_modes()") Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2024-06-09RAS/AMD/ATL: Expand helpers for adding and removing base and holeJohn Allen
The ret_addr field in struct addr_ctx contains the intermediate value of the returned address as it passes through multiple steps in the translation process. Currently, adding the DRAM base and legacy hole is only done once, so it operates directly on the intermediate value. However, for DF 4.5 non-power-of-2 denormalization, adding and removing the DRAM base and legacy hole needs to be done for multiple temporary address values. During this process, the intermediate value should not be lost so the ret_addr value can't be reused. Update the existing 'add' helper to operate on an arbitrary address and introduce a new 'remove' helper to do the inverse operations.

It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). The refactoring is mostly trivial except for "usbtouchscreen.c" file. Here, in the "mtouch_alloc" and "nexio_alloc" functions, it is necessary to use a variable with a predefined type instead of the "usbtouch->priv" variable (void * type). This way, the "sizeof" operator can now know the correct size. Moreover, we need to set the "usbtouch->priv" pointer after the memory allocation since now the "kmalloc" return value is not assigned directly. This patch has no effect on runtime behavior.

Qualcomm's EMAC4 integration supports only up to 36 bit width (as opposed to the addr64 register indicating 40 bit width). Let's indicate that in the platform driver to avoid a scenario where the driver will allocate descriptors of size that is supported by the CPU which in our case is 36 bit, but as the addr64 register is still capable of 40 bits the device will use two descriptors as one address.

2024-06-09iio: chemical: bme680: Fix sensor data read operationVasileios Amoiridis
A read operation is happening as follows: a) Set sensor to forced mode b) Sensor measures values and update data registers and sleeps again c) Read data registers In the current implementation the read operation happens immediately after the sensor is set to forced mode so the sensor does not have the time to update properly the registers. This leads to the following 2 problems: 1) The first ever value which is read by the register is always wrong 2) Every read operation, puts the register into forced mode and reads the data that were calculated in the previous conversion. This behaviour was tested in 2 ways: 1) The internal meas_status_0 register was read before and after every read operation in order to verify that the data were ready even before the register was set to forced mode and also to check that after the forced mode was set the new data were not yet ready. 2) Physically changing the temperature and measuring the temperature This commit adds the waiting time in between the set of the forced mode and the read of the data. The function is taken from the Bosch BME68x Sensor API [1].
