2023-01-13drm/vc4: bo: Fix unused variable warningMaxime Ripard1-1/+0
Commit 07a2975c65f2 ("drm/vc4: bo: Fix drmm_mutex_init memory hog") removed the only use of the ret variable, but didn't remove the variable itself leading to a unused variable warning. Remove that variable.

2023-01-12drm/vc4: bo: Fix drmm_mutex_init memory hogMaxime Ripard1-3/+2
Commit 374146cad469 ("drm/vc4: Switch to drmm_mutex_init") converted, among other functions, vc4_create_object() to use drmm_mutex_init(). However, that function is used to allocate a BO, and therefore the mutex needs to be freed much sooner than when the DRM device is removed from the system. For each buffer allocation we thus end up allocating a small structure as part of the DRM-managed mechanism that is never freed, eventually leading us to no longer having any free memory anymore. Let's switch back to mutex_init/mutex_destroy to deal with it properly.

2023-01-12drm: Optimize drm buddy top-down allocation methodArunpravin Paneer Selvam1-27/+54
We are observing performance drop in many usecases which include games, 3D benchmark applications,etc.. To solve this problem, We are strictly not allowing top down flag enabled allocations to steal the memory space from cpu visible region. The idea is, we are sorting each order list entries in ascending order and compare the last entry of each order list in the freelist and return the max block. This patch improves the 3D benchmark scores and solves fragmentation issues. All drm buddy selftests are verfied. drm_buddy: pass:6 fail:0 skip:0 total:6 Signed-off-by: Arunpravin Paneer Selvam <[email protected]> Acked-by: Christian König <[email protected]> Acked-by: Alex Deucher <[email protected]> Reviewed-by: Matthew Auld <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Christian König <[email protected]> CC: Cc: [email protected] # 5.18+

The branch is explicitly taken if ttm == NULL which means that to avoid a null pointer reference the ttm object can not be used inside. Switch back to dst_mem to avoid kernel oops'es. This fixes kernel oops'es with any buffer objects which don't have ttm_tt, e.g. with vram based screen objects on vmwgfx.

User resource lookups used rcu to avoid two extra atomics. Unfortunately the rcu paths were buggy and it was easy to make the driver crash by submitting command buffers from two different threads. Because the lookups never show up in performance profiles replace them with a regular spin lock which fixes the races in accesses to those shared resources.

2023-01-03drm/scheduler: Fix lockup in drm_sched_entity_kill()Dmitry Osipenko2-3/+3
The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy() while userspace process is exiting or being killed. First time it's invoked when sched entity is flushed and second time when entity is released. This causes a lockup within wait_for_completion(entity_idle) due to how completion API works. Calling wait_for_completion() more times than complete() was invoked is a error condition that causes lockup because completion internally uses counter for complete/wait calls. The complete_all() must be used instead in such cases. This patch fixes lockup of Panfrost driver that is reproducible by killing any application in a middle of 3d drawing operation.

ipu_src_rect_width() was introduced to support odd screen resolutions such as 1366x768 by internally rounding up primary plane width to a multiple of 8 and compensating with reduced horizontal blanking. This also caused overlay plane width to be rounded up, which was not intended. Fix overlay plane width by limiting the rounding up to the primary plane. drm_rect_width(&new_state->src) >> 16 is the same value as drm_rect_width(dst) because there is no plane scaling support.

Conditionally increase the number of lines held after vsync only for SoCs using AFBC, leaving the default value for all the others.

2022-12-30drm/i915/dsi: add support for ICL+ native MIPI GPIO sequenceJani Nikula3-3/+95
Starting from ICL, the default for MIPI GPIO sequences seems to be using native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse many pins that quite frankly seem scary to poke based on the VBT sequences. We pretty much have to trust that the board is configured such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for anything else. MIPI sequence v4 also adds a flag to fall back to non-native sequences. v5: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler() too (Ville) - References instead of Closes issue 6131 because this does not fix everything v4: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville) v3: - Fix -Wbitwise-conditional-parentheses (kernel test robot <[email protected]>) v2: - Fix HPD pin output set (impacts GPIOs 0 and 5) - Fix GPIO data output direction set (impacts GPIOs 4 and 9) - Reduce register accesses to single intel_de_rwm() References: https://gitlab.freedesktop.org/drm/intel/-/issues/6131 Cc: Ville Syrjälä <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Reviewed-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit f087cfe6fcff58044f7aa3b284965af47f472fb0) Cc: [email protected] # 6.1 Signed-off-by: Rodrigo Vivi <[email protected]>

2022-12-30kbuild: rpm-pkg: add libelf-devel as alternative for BuildRequiresMasahiro Yamada1-1/+2
Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b ("kbuild: add ability to make source rpm buildable using koji"). The relevant package name in openSUSE is libelf-devel. Add it as an alternative package. BTW, if it is impossible to solve the build requirement, the final resort would be: $ make RPMOPTS=--nodeps rpm-pkg This passes --nodeps to the rpmbuild command so it will not verify build dependencies. This is useful to test rpm builds on non-rpm system. On Debian/Ubuntu, for example, you can install rpmbuild by 'apt-get install rpm'. NOTE1: Likewise, it is possible to bypass the build dependency check for debian package builds: $ make DPKG_FLAGS=-d deb-pkg NOTE2: The 'or' operator is supported since RPM 4.13. So, old distros such as CentOS 7 will break. I suggest installing newer rpmbuild in such cases.

commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost rule") moved 'vmlinux.o' inside modpost-args, possibly before some of the other options.

As a result, the '-T' option is misinterpreted as a positional argument, and the build fails: make -f ./scripts/Makefile.modpost scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order -T: No such file or directory make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1 make: *** [Makefile:1960: modpost] Error 2 The fix is to move all options before 'vmlinux.o' in modpost-args.

2022-12-30arch: fix broken BuildID for arm64 and riscvMasahiro Yamada1-0/+5
Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux since commit 994b7ac1697b ("arm64: remove special treatment for the link order of head.o"). The issue is that the type of .notes section, which contains the BuildID, changed from NOTES to PROGBITS. Ard Biesheuvel figured out that whichever object gets linked first gets to decide the type of a section. The PROGBITS type is the result of the compiler emitting .note.GNU-stack as PROGBITS rather than NOTE. While Ard provided a fix for arm64, I want to fix this globally because the same issue is happening on riscv since commit 2348e6bf4421 ("riscv: remove special treatment for the link order of head.o"). This problem will happen in general for other architectures if they start to drop unneeded entries from scripts/head-object-list.txt. Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

2022-12-30drm/i915/uc: Fix two issues with over-size firmware filesJohn Harrison1-14/+28
In the case where a firmware file is too large (e.g. someone downloaded a web page ASCII dump from github...), the firmware object is released but the pointer is not zerod. If no other firmware file was found then release would be called again leading to a double kfree. Also, the size check was only being applied to the initial firmware load not any of the subsequent attempts. So move the check into a wrapper that is used for all loads.

2022-12-30drm/i915: improve the catch-all evict to handle lock contentionMatthew Auld6-26/+82
The catch-all evict can fail due to object lock contention, since it only goes as far as trylocking the object, due to us already holding the vm->mutex. Doing a full object lock here can deadlock, since the vm->mutex is always our inner lock. Add another execbuf pass which drops the vm->mutex and then tries to grab the object will the full lock, before then retrying the eviction. This should be good enough for now to fix the immediate regression with userspace seeing -ENOSPC from execbuf due to contended object locks during GTT eviction. v2 (Mani) - Also revamp the docs for the different passes. Testcase: igt@gem_ppgtt@shrink-vs-evict-* Fixes: 7e00897be8bf ("drm/i915: Add object locking to i915_gem_evict_for_node and i915_gem_evict_something, v2.")
