2023-03-01drm/amd/display: Don't restrict bpc to 8 bpcHarry Wentland
This will let us pass the kms_hdr.bpc_switch IGT test. The reason the bpc restriction was required is historical. At one point in time we were not falling back to a lower bpc when we didn't have enough bandwidth for the maximum bpc reported by a display. This meant that we couldn't enable some high refresh modes unless we limitted the bpc. Starting with this patch the issue is fixed: commit cbd14ae7ea93 ("drm/amd/display: Fix incorrectly pruned modes with deep color") This patch implemented a fallback mechanism if mode validation failed at the max bpc. This means users now automatically get all modes that can be supported by at least 6 bpc. The driver will enable the mode with the highest possible bpc that is supported by the display. v2: - explain why this is no longer needed (Michel) - refer to commit that fixed bpc fallback (Michel) Signed-off-by: Harry Wentland <harry.wentland@amd.com> Cc: Pekka Paalanen <ppaalanen@gmail.com> Cc: Sebastian Wick <sebastian.wick@redhat.com> Cc: Vitaly.Prosyak@amd.com Cc: Joshua Ashton <joshua@froggi.es> Cc: dri-devel@lists.freedesktop.org Cc: amd-gfx@lists.freedesktop.org Cc: Michel Dänzer <michel.daenzer@mailbox.org> Reviewed-by: Joshua Ashton <joshua@froggi.es> Reviewed-by: Michel Dänzer <mdaenzer@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2023-03-01drm/radeon: Fix eDP for single-display iMac11,2Mark Hawrylak
Apple iMac11,2 (mid 2010) also with Radeon HD-4670 that has the same issue as iMac10,1 (late 2009) where the internal eDP panel stays dark on driver load. This patch treats iMac11,2 the same as iMac10,1, so the eDP panel stays active. Additional steps: Kernel boot parameter radeon.nomodeset=0 required to keep the eDP panel active.

2023-03-01riscv: Bump COMMAND_LINE_SIZE value to 1024Alexandre Ghiti
Increase COMMAND_LINE_SIZE as the current default value is too low for syzbot kernel command line. There has been considerable discussion on this patch that has led to a larger patch set removing COMMAND_LINE_SIZE from the uapi headers on all ports. That's not quite done yet, but it's gotten far enough we're confident this is not a uABI change so this is safe.

2023-03-01cifs: Fix memory leak in direct I/ODavid Howells
When __cifs_readv() and __cifs_writev() extract pages from a user-backed iterator into a BVEC-type iterator, they set ->bv_need_unpin to note whether they need to unpin the pages later. However, in both cases they examine the BVEC-type iterator and not the source iterator - and so bv_need_unpin doesn't get set and the pages are leaked. I think this may be responsible for the generic/208 xfstest failing occasionally with: WARNING: CPU: 0 PID: 3064 at mm/gup.c:218 try_grab_page+0x65/0x100 RIP: 0010:try_grab_page+0x65/0x100 follow_page_pte+0x1a7/0x570 __get_user_pages+0x1a2/0x650 __gup_longterm_locked+0xdc/0xb50 internal_get_user_pages_fast+0x17f/0x310 pin_user_pages_fast+0x46/0x60 iov_iter_extract_pages+0xc9/0x510 ? __kmalloc_large_node+0xb1/0x120 ? __kmalloc_node+0xbe/0x130 netfs_extract_user_iter+0xbf/0x200 [netfs] __cifs_writev+0x150/0x330 [cifs] vfs_write+0x2a8/0x3c0 ksys_pwrite64+0x65/0xa0 with the page refcount going negative. This is less unlikely than it seems because the page is being pinned, not simply got, and so the refcount increased by 1024 each time, and so only needs to be called around ~2097152 for the refcount to go negative. Further, the test program (aio-dio-invalidate-failure) uses a 32MiB static buffer and all the PTEs covering it refer to the same page because it's never written to. The warning in try_grab_page(): if (WARN_ON_ONCE(folio_ref_count(folio) <= 0)) return -ENOMEM; then trips and prevents us ever using the page again for DIO at least.

2023-03-01s390/extmem: return correct segment type in __segment_load()Gerald Schaefer
Commit f05f62d04271f ("s390/vmem: get rid of memory segment list") reshuffled the call to vmem_add_mapping() in __segment_load(), which now overwrites rc after it was set to contain the segment type code. As result, __segment_load() will now always return 0 on success, which corresponds to the segment type code SEG_TYPE_SW, i.e. a writeable segment. This results in a kernel crash when loading a read-only segment as dcssblk block device, and trying to write to it. Instead of reshuffling code again, make sure to return the segment type on success, and also describe this rather delicate and unexpected logic in the function comment. Also initialize new segtype variable with invalid value, to prevent possible future confusion.

2023-03-01capability: just use a 'u64' instead of a 'u32[2]' arrayLinus Torvalds
Back in 2008 we extended the capability bits from 32 to 64, and we did it by extending the single 32-bit capability word from one word to an array of two words. It was then obfuscated by hiding the "2" behind two macro expansions, with the reasoning being that maybe it gets extended further some day. That reasoning may have been valid at the time, but the last thing we want to do is to extend the capability set any more. And the array of values not only causes source code oddities (with loops to deal with it), but also results in worse code generation. It's a lose-lose situation. So just change the 'u32[2]' into a 'u64' and be done with it. We still have to deal with the fact that the user space interface is designed around an array of these 32-bit values, but that was the case before too, since the array layouts were different (ie user space doesn't use an array of 32-bit values for individual capability masks, but an array of 32-bit slices of multiple masks). So that marshalling of data is actually simplified too, even if it does remain somewhat obscure and odd. This was all triggered by my reaction to the new "cap_isidentical()" introduced recently. By just using a saner data structure, it went from unsigned __capi; CAP_FOR_EACH_U32(__capi) { if (a.cap[__capi] != b.cap[__capi]) return false; } return true; to just being return a.val == b.val; instead. Which is rather more obvious both to humans and to compilers.

Commit 47894e0fa6a5 ("virt/sev-guest: Prevent IV reuse in the SNP guest driver") changed the behavior associated with the return value when the caller does not supply a large enough certificate buffer. Prior to the commit a value of -EIO was returned. Now, 0 is returned. This breaks the established ABI with the user. Change the code to detect the buffer size error and return -EIO.

2023-02-28riscv, lib: Fix Zbb strncmpBjörn Töpel
The Zbb optimized strncmp has two parts; a fast path that does XLEN/8B per iteration, and a slow that does one byte per iteration. The idea is to compare aligned XLEN chunks for most of strings, and do the remainder tail in the slow path. The Zbb strncmp has two issues in the fast path: Incorrect remainder handling (wrong compare): Assume that the string length is 9. On 64b systems, the fast path should do one iteration, and one iteration in the slow path. Instead, both were done in the fast path, which lead to incorrect results. An example: strncmp("/dev/vda", "/dev/", 5); Correct by changing "bgt" to "bge". Missing NULL checks in the second string: This could lead to incorrect results for: strncmp("/dev/vda", "/dev/vda\0", 8); Correct by adding an additional check.

For now, active references are taken to perform some work in an AG on behalf of a high level operation; passive references are used by lower level code to finish operations started by other threads.

Bus-speed could be default(12.5MHz) or defined by users in dts. Dw-i3c-master should not hard-code the initial speed to be I3C_BUS_TYP_I3C_SCL_RATE (12.5MHz) And because of Synopsys's I3C controller limit (hcnt/lcnt register length) and core-clk provided, there is a limit to bus speed, too. For example, when core-clk is 250 MHz, the bus speed cannot be lowered below 1MHz. Tested: tested with an i3c sensor and captured with a logic analyzer.

2023-02-28MIPS: Workaround clang inline compat branch issueJiaxun Yang
Clang is unable to handle the situation that a chunk of inline assembly ends with a compat branch instruction and then compiler generates another control transfer instruction immediately after this compat branch. The later instruction will end up in forbidden slot and cause exception. Workaround by add a option to control the use of compact branch. Currently it's selected by CC_IS_CLANG and hopefully we can change it to a version check in future if clang manages to fix it. Fix boot on boston board.

As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message.

2023-02-28ASoC: mchp-pdmc: fix poc noises when startingMark Brown
Merge series from Claudiu Beznea <claudiu.beznea@microchip.com>: To start capture on Microchip PDMC the enable bits for each supported microphone need to be set. After this bit is set the PDMC starts to receive data from microphones and it considers this data as valid data. Thus if microphones are not ready the PDMC captures anyway data from its lines. This data is interpreted by the human ear as poc noises. To avoid this the following software workaround need to be applied when starting capture: 1/ enable PDMC channel 2/ wait 150ms 3/ execute 16 dummy reads from RHR 4/ clear interrupts 5/ enable interrupts 6/ enable DMA channel For this workaround to work step 6 need to be executed at the end. For step 6 was added patch 1/3 from this series. With this, component DAI driver sets its struct snd_soc_component_driver::start_dma_last = 1 and proper action is taken based on this flag when starting DAI trigger vs DMA.
