Small APUs(i.e., consumer, embedded products) usually have a small carveout device memory which can't satisfy most compute workloads memory allocation requirements. We can't even run a Basic MNIST Example with a default 512MB carveout. https://github.com/pytorch/examples/tree/main/mnist. Error Log: "torch.cuda.OutOfMemoryError: HIP out of memory. Tried to allocate 84.00 MiB. GPU 0 has a total capacity of 512.00 MiB of which 0 bytes is free. Of the allocated memory 103.83 MiB is allocated by PyTorch, and 22.17 MiB is reserved by PyTorch but unallocated" Though we can change BIOS settings to enlarge carveout size, which is inflexible and may bring complaint. On the other hand, the memory resource can't be effectively used between host and device. The solution is MI300A approach, i.e., let VRAM allocations go to GTT. Then device and host can flexibly and effectively share memory resource. v2: Report local_mem_size_private as 0. (Felix) Signed-off-by:

Allocate cleared blocks in the bias range when the DRM buddy's clear avail is zero. This will validate the bias range allocation in scenarios like system boot when no cleared blocks are available and exercise the fallback path too. The resulting blocks should always be dirty. v1:(Matthew) - move the size to the variable declaration section. - move the mm.clear_avail init to allocator init. Signed-off-by:

Problem statement: During the system boot time, an application request for the bulk volume of cleared range bias memory when the clear_avail is zero, we dont fallback into normal allocation method as we had an unnecessary clear_avail check which prevents the fallback method leads to fb allocation failure following system goes into unresponsive state. Solution: Remove the unnecessary clear_avail check in the range bias allocation function. v2: add a kunit for this corner case (Daniel Vetter) Signed-off-by:

We must always register the DRM bridge, since zynqmp_dp_hpd_work_func calls drm_bridge_hpd_notify, which in turn expects hpd_mutex to be initialized. We do this before zynqmp_dpsub_drm_init since that calls drm_bridge_attach.

This reverts commit 8a91b29f. The regulator_disable() added by the original commit solves one kind of regulator imbalance but adds another one as it allows the regulator to be disabled one more time than it is enabled in the following scenario: 1. Start video pipeline -> sn65dsi83_atomic_pre_enable -> regulator_enable 2. PLL lock fails -> regulator_disable 3. Stop video pipeline -> sn65dsi83_atomic_disable -> regulator_disable The reason is clear from the code flow, which looks like this (after removing unrelated code): static void sn65dsi83_atomic_pre_enable() { regulator_enable(ctx->vcc); if (PLL failed locking) { regulator_disable(ctx->vcc); <---- added by patch being reverted return; } } static void sn65dsi83_atomic_disable() { regulator_disable(ctx->vcc); } The use case for introducing the additional regulator_disable() was removing the module for debugging (see link below for the discussion). If the module is removed after a .atomic_pre_enable, i.e. with an active pipeline from the DRM point of view, .atomic_disable is not called and thus the regulator would not be disabled. According to the discussion however there is no actual use case for removing the module with an active pipeline, except for debugging/development. On the other hand, the occurrence of a PLL lock failure is possible due to any physical reason (e.g. a temporary hardware failure for electrical reasons) so handling it gracefully should be supported. As there is no way for .atomic[_pre]_enable to report an error to the core, the only clean way to support it is calling regulator_disabled() only in .atomic_disable, unconditionally, as it was before.

Make sure we catch FW inconsistencies by adding a default to the switch statement, and flagging the group state as unknown in that case.

When you create a submenu using the 'menu' syntax, there is no ambiguity about its end because the code between 'menu' and 'endmenu' becomes the submenu. In contrast, 'menuconfig' does not have the corresponding end marker. Instead, the end of the submenu is inferred from symbol dependencies. This is detailed in Documentation/kbuild/kconfig-language.rst, starting line 348. It outlines two methods to place the code under the submenu: (1) Open an if-block immediately after 'menuconfig', enclosing the submenu content within it (2) Add 'depends on' to every symbol intended for the submenu Many subsystems opt for (1) because it reliably maintains the submenu structure. The DRM subsystem adopts (2). The submenu ends when the sequence of 'depends on DRM' breaks. It can be confirmed by running a GUI frontend such as 'make menuconfig' and visiting the DRM menu: < > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ---- If you toggle this, you will notice most of the DRM-related options appear below it, not in the submenu. I highly recommend the approach (1). Obviously, (2) is not reliable, as the submenu breaks whenever someone forgets to add 'depends on DRM'. This commit encloses the entire DRM configuration with 'if DRM' and 'endif', except for DRM_PANEL_ORIENTATION_QUIRKS. Note: Now, 'depends on DRM' properties inside the if-block are all redundant. I leave it as follow-up cleanups. Signed-off-by:Masahiro Yamada <masahiroy@kernel.org> Acked-by:
