The th1520 support xtheadvector [1] so it can be included in the devicetree. Also include vlenb for the cpu. And set vlenb=16 [2]. This can be tested by passing the "mitigations=off" kernel parameter.

…lity All PLLs found on TH1520 SoC take 21250ns at maximum to lock, and their lock status is indicated by register PLL_STS (offset 0x80 inside AP clock controller). We should poll the register to ensure the PLL actually locks after enabling it. Furthermore, a 30us delay is added after enabling the PLL, after which the PLL could be considered stable as stated by vendor clock code.

On TH1520 SoC, c910_clk feeds the CPU cluster. It could be glitchlessly reparented to one of the two PLLs: either to cpu_pll0 indirectly through c910_i0_clk, or to cpu_pll1 directly. To achieve glitchless rate change, customized clock operations are implemented for c910_clk: on rate change, the PLL not currently in use is configured to the requested rate first, then c910_clk reparents to it. Additionally, c910_bus_clk, which in turn takes c910_clk as parent, has a frequency limit of 750MHz. A clock notifier is registered on c910_clk to adjust c910_bus_clk on c910_clk rate change.

Add operating point table for CPU cores, and wire up clocks for CPU nodes. This patch isn't intended for upstreaming but only for testing purpose, since the PMIC driver for scaling CPU voltage isn't ready yet. Only operating points whose voltage is satisified by Lichee Module 4A's PMIC default, i.e. <= 1.5GHz, are enabled.

Only DC8200 is being supported now, and only the main framebuffer is set up (as the DRM primary plane). Support for more DC models and more features is my further targets. As the display controller is delivered to SoC vendors as a whole part, this driver does not use component framework and extra bridges inside a SoC is expected to be implemented as dedicated bridges (this driver properly supports bridge chaining).

Use BPF_TRAMP_F_INDIRECT flag to detect struct ops and emit proper prologue and epilogue for this case. With this patch, all of the struct_ops related testcases (except struct_ops_multi_pages) passed on LoongArch. The testcase struct_ops_multi_pages failed is because the actual image_pages_cnt is 40 which is bigger than MAX_TRAMP_IMAGE_PAGES. Before: $ sudo ./test_progs -t struct_ops -d struct_ops_multi_pages ... WATCHDOG: test case struct_ops_module/struct_ops_load executes for 10 seconds...

The namespaces can access the controller's admin request_queue, and stale references on the namespaces may exist after tearing down the controller. Ensure the admin request_queue is active by moving the controller's 'put' to after all controller references have been released to ensure no one is can access the request_queue.

Use BPF_TRAMP_F_INDIRECT flag to detect struct ops and emit proper prologue and epilogue for this case. With this patch, all of the struct_ops related testcases (except struct_ops_multi_pages) passed on LoongArch. The testcase struct_ops_multi_pages failed is because the actual image_pages_cnt is 40 which is bigger than MAX_TRAMP_IMAGE_PAGES. Before: $ sudo ./test_progs -t struct_ops -d struct_ops_multi_pages ... WATCHDOG: test case struct_ops_module/struct_ops_load executes for 10 seconds... After: $ sudo ./test_progs -t struct_ops -d struct_ops_multi_pages ... #15 bad_struct_ops:OK ... torvalds#399 struct_ops_autocreate:OK ... torvalds#400 struct_ops_kptr_return:OK ... torvalds#401 struct_ops_maybe_null:OK ... torvalds#402 struct_ops_module:OK ... torvalds#404 struct_ops_no_cfi:OK ... torvalds#405 struct_ops_private_stack:SKIP ... torvalds#406 struct_ops_refcounted:OK Summary: 8/25 PASSED, 3 SKIPPED, 0 FAILED Signed-off-by: Tiezhu Yang <[email protected]> Signed-off-by: Huacai Chen <[email protected]> Signed-off-by: maoxiaochuan <[email protected]>

[ Upstream commit 48918ca ] The test starts a workload and then opens events. If the events fail to open, for example because of perf_event_paranoid, the gopipe of the workload is leaked and the file descriptor leak check fails when the test exits. To avoid this cancel the workload when opening the events fails.

commit 1d3ad18 upstream. syzbot reported a BUG_ON in ext4_es_cache_extent() when opening a verity file on a corrupted ext4 filesystem mounted without a journal. The issue is that the filesystem has an inode with both the INLINE_DATA and EXTENTS flags set: EXT4-fs error (device loop0): ext4_cache_extents:545: inode #15: comm syz.0.17: corrupted extent tree: lblk 0 < prev 66 Investigation revealed that the inode has both flags set: DEBUG: inode 15 - flag=1, i_inline_off=164, has_inline=1, extents_flag=1 This is an invalid combination since an inode should have either: - INLINE_DATA: data stored directly in the inode - EXTENTS: data stored in extent-mapped blocks Having both flags causes ext4_has_inline_data() to return true, skipping extent tree validation in __ext4_iget(). The unvalidated out-of-order extents then trigger a BUG_ON in ext4_es_cache_extent() due to integer underflow when calculating hole sizes. Fix this by detecting this invalid flag combination early in ext4_iget() and rejecting the corrupted inode.
