2021-01-07dmabuf: fix use-after-free of dmabuf's file->f_inodeCharan Teja Reddy1-4/+17
It is observed 'use-after-free' on the dmabuf's file->f_inode with the race between closing the dmabuf file and reading the dmabuf's debug info. Consider the below scenario where P1 is closing the dma_buf file and P2 is reading the dma_buf's debug info in the system: P1 P2 dma_buf_debug_show() dma_buf_put() __fput() file->f_op->release() dput() .... dentry_unlink_inode() iput(dentry->d_inode) (where the inode is freed) mutex_lock(&db_list.lock) read 'dma_buf->file->f_inode' (the same inode is freed by P1) mutex_unlock(&db_list.lock) dentry->d_op->d_release()--> dma_buf_release() ..... mutex_lock(&db_list.lock) removes the dmabuf from the list mutex_unlock(&db_list.lock) In the above scenario, when dma_buf_put() is called on a dma_buf, it first frees the dma_buf's file->f_inode(=dentry->d_inode) and then removes this dma_buf from the system db_list. In between P2 traversing the db_list tries to access this dma_buf's file->f_inode that was freed by P1 which is a use-after-free case. Since, __fput() calls f_op->release first and then later calls the d_op->d_release, move the dma_buf's db_list removal from d_release() to f_op->release(). This ensures that dma_buf's file->f_inode is not accessed after it is released.

2021-01-06drm/amdgpu/display: drop DCN support for aarch64Alex Deucher13-73/+1
From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64.

2021-01-06drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCOXiaojian Du2-1/+59
This patch is to improve the fine grain tuning function for RV/RV2/PCO. The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage to config gfxclk. Meanwhile, another sysfs node -- power_dpm_force_perfomance_level also affects the gfx clk. It will cause confusion when these two sysfs nodes works together. So this patch adds one flag to avoid this confusion, the flag will make these two sysfs nodes work separately. The flag is set as "disabled" by default, so the fine grain tuning function will be disabled by default. Only when power_dpm_force_perfomance_level is changed to "manual" mode, the flag will be set as "enabled", and the fine grain tuning function will be enabled. In other profile modes, including "auto", "high", "low", "profile_peak", "profile_standard", "profile_min_sclk", "profile_min_mclk", the flag will be set as "disabled", and the od range of fine grain tuning function will be restored default value.

2021-01-06drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCOXiaojian Du2-17/+98
This patch is to improve the fine grain tuning function for RV/RV2/PCO. This patch adds two new commands: "restore" and "commit". This function uses the pp_od_clk_voltage sysfs file to configure the min and max value of gfx clock frequency manually or restore the default value. Command guide: echo "s level value" > pp_od_clk_voltage "s" - set the sclk frequency "level" - 0 or 1, "0" represents the min value, "1" represents the max value "value" - the target value of sclk frequency, it should be limited in the safe range echo "r" > pp_od_clk_voltage "r" - reset the sclk frequency, restore the default value instantly echo "c" > pp_od_clk_voltage "c" - commit the min and max value of sclk frequency to the system only after the commit command, the target values set by "s" command will take effect. Example: 1)change power profile from "auto" to "manual" $ cat power_dpm_force_performance_level auto $ echo "manual" > power_dpm_force_performance_level $ cat power_dpm_force_performance_level manual 2)check the default sclk frequency $ cat pp_od_clk_voltage OD_SCLK: 0: 200Mhz 1: 1400Mhz OD_RANGE: SCLK: 200MHz 1400MHz 3)use "s" -- set command to configure the min and max sclk frequency $ echo "s 0 600" > pp_od_clk_voltage $ echo "s 1 1000" > pp_od_clk_voltage $ echo "c" > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 600Mhz 1: 1000Mhz OD_RANGE: SCLK: 200MHz 1400MHz 4)use "r" -- reset command to restore the min or max sclk frequency $ echo "r" > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 200Mhz 1: 1400Mhz OD_RANGE: SCLK: 200MHz 1400MHz Signed-off-by: Xiaojian Du <[email protected]> Reviewed-by: Evan Quan <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

For cancelling io_uring requests it needs either to be able to run currently enqueued task_works or having it shut down by that moment. Otherwise io_uring_cancel_files() may be waiting for requests that won't ever complete. Go with the first way and do cancellations before setting PF_EXITING and so before putting the task_work infrastructure into a transition state where task_work_run() would better not be called.

2020-12-30intel_idle: add SnowRidge C-state tableArtem Bityutskiy1-1/+40
Add C-state table for the SnowRidge SoC which is found on Intel Jacobsville platforms. The following has been changed. 1. C1E latency changed from 10us to 15us. It was measured using the open source "wult" tool (the "nic" method, 15us is the 99.99th percentile). 2. C1E power break even changed from 20us to 25us, which may result in less C1E residency in some workloads. 3. C6 latency changed from 50us to 130us. Measured the same way as C1E. The C6 C-state is supported only by some SnowRidge revisions, so add a C-state table commentary about this. On SnowRidge, C6 support is enumerated via the usual mechanism: "mwait" leaf of the "cpuid" instruction. The 'intel_idle' driver does check this leaf, so even though C6 is present in the table, the driver will only use it if the CPU does support it.

2020-12-30cpufreq: intel_pstate: Fix fast-switch fallback pathRafael J. Wysocki1-1/+0
When sugov_update_single_perf() falls back to the "frequency" path due to the missing scale-invariance, it will call cpufreq_driver_fast_switch() via sugov_fast_switch() and the driver's ->fast_switch() callback will be invoked, so it must not be NULL. However, after commit a365ab6b9dfb ("cpufreq: intel_pstate: Implement the ->adjust_perf() callback") intel_pstate sets ->fast_switch() to NULL when it is going to use intel_cpufreq_adjust_perf(), which is a mistake, because on x86 the scale-invariance may be turned off dynamically, so modify it to retain the original ->adjust_perf() callback pointer.
