Commit 156af9de0932 ("arm64: tegra: Add Tegra234 I2C devicetree nodes") populated the I2C device nodes for Tegra234. One of these nodes contains the property 'nvidia,hw-instance-id' which is neither documented or used. Remove this unused property.

2022-11-21arm64: tegra: Fix Prefetchable aperture ranges of Tegra234 PCIe controllersVidya Sagar1-3/+3
commit edf408b946d3 ("PCI: dwc: Validate iATU outbound mappings against hardware constraints") exposes an issue with the existing partitioning of the aperture space where the Prefetchable apertures of controllers C5, C7 and C9 in Tegra234 cross the 32GB boundary hardware constraint. This patch makes sure that the Prefetchable region doesn't spill over the 32GB boundary.

2022-11-21arm64: tegra: Add NVDEC on Tegra234Mikko Perttunen1-0/+36
Add a device tree node for NVDEC on Tegra234. Booting the firmware requires some information regarding offsets within the firmware binary. These are passed through the device tree, but since the values vary depending on the firmware version, and the firmware itself is not available to the OS, the flasher is expected to provide a device tree overlay with values corresponding to the firmware it is flashing. The overlay then replaces the placeholder values here. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

2022-11-21arm64: dts: mediatek: mt8195: Fix CPUs capacity-dmips-mhzAngeloGioacchino Del Regno1-4/+4
The capacity-dmips-mhz parameter was miscalculated: this SoC runs the first (Cortex-A55) cluster at a maximum of 2000MHz and the second (Cortex-A78) cluster at a maximum of 3000MHz. In order to calculate the right capacity-dmips-mhz, the following test was performed: 1. CPUFREQ governor was set to 'performance' on both clusters 2. Ran dhrystone with 500000000 iterations for 10 times on each cluster 3. Calculate the mean result for each cluster 4. Calculate DMIPS/MHz: dmips_mhz = dmips_per_second / cpu_mhz 5. Scale results to 1024: result_c0 = (dmips_mhz_c0 - min_dmips_mhz(c0, c1)) / (max_dmips_mhz(c0, c1) - min_dmips_mhz(c0, c1)) * 1024 The mean results for this SoC are: Cluster 0 (LITTLE): 11990400 Dhry/s Cluster 1 (BIG): 59809036 Dhry/s The calculated scaled results are: Cluster 0: 307,934312801831 (rounded to 308) Cluster 1: 1024 Fixes: 37f2582883be ("arm64: dts: Add mediatek SoC mt8195 and evaluation board") Signed-off-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Link: https://lore.kernel.org/r/20221005093404.33102-1-angelogioacchino.delregno@collabora.com Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>

2022-11-21LoongArch: Set _PAGE_DIRTY only if _PAGE_WRITE is set in {pmd,pte}_mkdirty()Huacai Chen1-2/+6
Now {pmd,pte}_mkdirty() set _PAGE_DIRTY bit unconditionally, this causes random segmentation fault after commit 0ccf7f168e17bb7e ("mm/thp: carry over dirty bit when thp splits on pmd"). The reason is: when fork(), parent process use pmd_wrprotect() to clear huge page's _PAGE_WRITE and _PAGE_DIRTY (for COW); then pte_mkdirty() set _PAGE_DIRTY as well as _PAGE_MODIFIED while splitting dirty huge pages; once _PAGE_DIRTY is set, there will be no tlb modify exception so the COW machanism fails; and at last memory corruption occurred between parent and child processes. So, we should set _PAGE_DIRTY only when _PAGE_WRITE is set in {pmd,pte}_ mkdirty(). Cc: stable@vger.kernel.org Cc: Peter Xu <peterx@redhat.com> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
