2023-01-02drm/tiny: ili9486: Do not assume 8-bit only SPI controllersCarlo Caione1-4/+9
The pixel data for the ILI9486 is always 16-bits wide and it must be sent over the SPI bus. When the controller is only able to deal with 8-bit transfers, this 16-bits data needs to be swapped before the sending to account for the big endian bus, this is on the contrary not needed when the SPI controller already supports 16-bits transfers. The decision about swapping the pixel data or not is taken in the MIPI DBI code by probing the controller capabilities: if the controller only suppors 8-bit transfers the data is swapped, otherwise it is not. This swapping/non-swapping is relying on the assumption that when the controller does support 16-bit transactions then the data is sent unswapped in 16-bits-per-word over SPI. The problem with the ILI9486 driver is that it is forcing 8-bit transactions also for controllers supporting 16-bits, violating the assumption and corrupting the pixel data. Align the driver to what is done in the MIPI DBI code by adjusting the transfer size to the maximum allowed by the SPI controller.

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 <lkp@intel.com>) 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 <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221219105955.4014451-1-jani.nikula@intel.com (cherry picked from commit f087cfe6fcff58044f7aa3b284965af47f472fb0) Cc: stable@vger.kernel.org # 6.1 Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

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.

2022-12-30kbuild: Fix running modpost with musl libcSamuel Holland1-11/+11
commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost rule") moved 'vmlinux.o' inside modpost-args, possibly before some of the other options. However, getopt() in musl libc follows POSIX and stops looking for options upon reaching the first non-option argument. 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.

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.
