So far, only the intermittent failure was +implemented. The permanent failure was achieved by resetting the entire +entropy source including its health test state and waiting for two or +more back-to-back health errors. + +This approach is appropriate for RCT, but not for APT as APT has a +non-linear cutoff value. Thus, this patch implements 2 cutoff values +for both RCT/APT. This implies that the health state is left untouched +when an intermittent failure occurs. The noise source is reset +and a new APT powerup-self test is performed. Yet, whith the unchanged +health test state, the counting of failures continues until a permanent +failure is reached. + +Any non-failing raw entropy value causes the health tests to reset. + +The intermittent error has an unchanged significance level of 2^-30. +The permanent error has a significance level of 2^-60. Considering that +this level also indicates a false-positive rate (see SP800-90B section 4.2) +a false-positive must only be incurred with a low probability when +considering a fleet of Linux kernels as a whole. Hitting the permanent +error may cause a panic(), the following calculation applies: Assuming +that a fleet of 10^9 Linux kernels run concurrently with this patch in +FIPS mode and on each kernel 2 health tests are performed every minute +for one year, the chances of a false positive is about 1:1000 +based on the binomial distribution. + +In addition, any power-up health test errors triggered with +jent_entropy_init are treated as permanent errors. + +A permanent failure causes the entire entropy source to permanently +return an error. This implies that a caller can only remedy the situation +by re-allocating a new instance of the Jitter RNG. In a subsequent +patch, a transparent re-allocation will be provided which also changes +the implied heuristic entropy assessment. + +In addition, when the kernel is booted with fips=1, the Jitter RNG +is defined to be part of a FIPS module. The permanent error of the +Jitter RNG is translated as a FIPS module error. In this case, the entire +FIPS module must cease operation. This is implemented in the kernel by +invoking panic(). + +The patch also fixes an off-by-one in the RCT cutoff value which is now +set to 30 instead of 31.

It was hard to say how + many of the differences between the two functions were on purpose + and how many of them were just an accident of how they were coded. +* Each function sometimes used "else if" to test for error bits and + sometimes didn't and again it was hard to say if this was on purpose + or just an accident. +* The two functions wouldn't notice whether "unknown" bits were + set. For instance, there seems to be a bit "DP_INTR_PLL_UNLOCKED" + and if it was set there would be no indication. +* The two functions wouldn't notice if more than one error was set. + +Let's fix this by being more consistent / explicit about what we're +doing. + +By design this could cause different handling for AUX transfers, +though I'm not actually aware of any bug fixed as a result of +this patch (this patch was created because we simply noticed how odd +the old code was by code inspection). Specific notes here: +1. In the old native transfer case if we got "done + wrong address" + we'd ignore the "wrong address" (because of the "else if"). Now we + won't. +2. In the old native transfer case if we got "done + timeout" we'd + ignore the "timeout" (because of the "else if"). Now we won't. +3. In the old native transfer case we'd see "nack_defer" and translate + it to the error number for "nack". This differed from the i2c + transfer case where "nack_defer" was given the error number for + "nack_defer". This 100% can't matter because the only user of this + error number treats "nack defer" the same as "nack", so it's clear + that the difference between the "native" and "i2c" was pointless + here. +4. In the old i2c transfer case if we got "done" plus any error + besides "nack" or "defer" then we'd ignore the error. Now we don't. +5. If there is more than one error signaled by the hardware it's + possible that we'll report a different one than we used to. I don't + know if this matters. If someone is aware of a case this matters we + should document it and change the code to make it explicit. +6. One quirk we keep (I don't know if this is important) is that in + the i2c transfer case if we see "done + defer" we report that as a + "nack". That seemed too intentional in the old code to just drop. + +After this change we will add extra logging, including: +* A warning if we see more than one error bit set. +* A warning if we see an unexpected interrupt. +* A warning if we get an AUX transfer interrupt when shouldn't. + +It actually turns out that as a result of this change then at boot we +sometimes see an error: + [drm:dp_aux_isr] *ERROR* Unexpected DP AUX IRQ 0x01000000 when not busy +That means that, during init, we are seeing DP_INTR_PLL_UNLOCKED.

This hardware issue impacts +NVIDIA server platforms that use more than two T241 chips +interconnected. Each chip has support for 320 {E}SPIs. + +This issue occurs when multiple packets from different GICs are +incorrectly interleaved at the target chip. The erratum text below +specifies exactly what can cause multiple transfer packets susceptible +to interleaving and GIC state corruption. GIC state corruption can +lead to a range of problems, including kernel panics, and unexpected +behavior. + +>From the erratum text: + "In some cases, inter-socket AXI4 Stream packets with multiple + transfers, may be interleaved by the fabric when presented to ARM + Generic Interrupt Controller. GIC expects all transfers of a packet + to be delivered without any interleaving. + + The following GICv3 commands may result in multiple transfer packets + over inter-socket AXI4 Stream interface: + - Register reads from GICD_I* and GICD_N* + - Register writes to 64-bit GICD registers other than GICD_IROUTERn* + - ITS command MOVALL + + Multiple commands in GICv4+ utilize multiple transfer packets, + including VMOVP, VMOVI, VMAPP, and 64-bit register accesses." + + This issue impacts system configurations with more than 2 sockets, + that require multi-transfer packets to be sent over inter-socket + AXI4 Stream interface between GIC instances on different sockets. + GICv4 cannot be supported.

The SPI interrupt deactivate path is not impacted by +the erratum. + +To fix this problem, implement a workaround that ensures read accesses +to the GICD_In{E} registers are directed to the chip that owns the +SPI, and disable GICv4.x features.

This doesn't make +a lot of sense. + +Time was spent finding potential users of this combination. Searching on +codesearch.debian.net showed that codebases often express semantical +expectations about O_DIRECTORY | O_CREAT which are completely contrary +to what our code has done and currently does. + +The expectation often is that this particular combination would create +and open a directory. This suggests users who tried to use that +combination would stumble upon the counterintuitive behavior no matter +if pre-v5.7 or post v5.7 and quickly realize neither semantics give them +what they want. For some examples see the code examples in [1] to [3] +and the discussion in [4]. + +There are various ways to address this issue. The lazy/simple option +would be to restore the pre-v5.7 behavior and to just live with that bug +forever. But since there's a real chance that the O_DIRECTORY | O_CREAT +quirk isn't relied upon we should try to get away with murder(ing bad +semantics) first. If we need to Frankenstein pre-v5.7 behavior later so +be it. + +So let's simply return EINVAL categorically for O_DIRECTORY | O_CREAT +combinations. In addition to cleaning up the old bug this also opens up +the possiblity to make that flag combination do something more intuitive +in the future. + +Starting with this commit the following semantics apply: + +(1) open("/tmp/d", O_DIRECTORY | O_CREAT) + * d doesn't exist: EINVAL + * d exists and is a regular file: EINVAL + * d exists and is a directory: EINVAL + +(2) open("/tmp/d", O_DIRECTORY | O_CREAT | O_EXCL) + * d doesn't exist: EINVAL + * d exists and is a regular file: EINVAL + * d exists and is a directory: EINVAL + +(3) open("/tmp/d", O_DIRECTORY | O_EXCL) + * d doesn't exist: ENOENT + * d exists and is a regular file: ENOTDIR + * d exists and is a directory: open directory + +One additional note, O_TMPFILE is implemented as: + + #define __O_TMPFILE 020000000 + #define O_TMPFILE (__O_TMPFILE | O_DIRECTORY) + #define O_TMPFILE_MASK (__O_TMPFILE | O_DIRECTORY | O_CREAT) + +For older kernels it was important to return an explicit error when +O_TMPFILE wasn't supported.

Thu, 6 Apr 2023 14:46:40 +0100 +Subject: soundwire: bus: Fix unbalanced pm_runtime_put() causing usage count + underflow + +From: Richard Fitzgerald + +[ Upstream commit e9537962519e88969f5f69cd0571eb4f6984403c ] + +This reverts commit +443a98e649b4 ("soundwire: bus: use pm_runtime_resume_and_get()") + +Change calls to pm_runtime_resume_and_get() back to pm_runtime_get_sync(). +This fixes a usage count underrun caused by doing a pm_runtime_put() even +though pm_runtime_resume_and_get() returned an error. + +The three affected functions ignore -EACCES error from trying to get +pm_runtime, and carry on, including a put at the end of the function. +But pm_runtime_resume_and_get() does not increment the usage count if it +returns an error. So in the -EACCES case you must not call +pm_runtime_put(). + +The documentation for pm_runtime_get_sync() says: + "Consider using pm_runtime_resume_and_get() ... as this is likely to + result in cleaner code." + +In this case I don't think it results in cleaner code because the +pm_runtime_put() at the end of the function would have to be conditional on +the return value from pm_runtime_resume_and_get() at the top of the +function. + +pm_runtime_get_sync() doesn't have this problem because it always +increments the count, so always needs a put. The code can just flow through +and do the pm_runtime_put() unconditionally. + +Signed-off-by: Richard Fitzgerald +Reviewed-by: Pierre-Louis Bossart +Link: https://lore.kernel.org/r/20230406134640.8582-1-rf@opensource.cirrus.com +Signed-off-by: Vinod Koul +Signed-off-by: Sasha Levin +--- + drivers/soundwire/bus.c | 15 ++++++++++----- + 1 file changed, 10 insertions(+), 5 deletions(-) + +diff --git a/drivers/soundwire/bus.c b/drivers/soundwire/bus.c +index 76515c33e639e..4fd221d0cc818 100644 +--- a/drivers/soundwire/bus.c ++++ b/drivers/soundwire/bus.c +@@ -571,9 +571,11 @@ int sdw_nread(struct sdw_slave *slave, u32 addr, size_t count, u8 *val) + { + int ret; + +- ret = pm_runtime_resume_and_get(&slave->dev); +- if (ret < 0 && ret != -EACCES) ++ ret = pm_runtime_get_sync(&slave->dev); ++ if (ret < 0 && ret != -EACCES) { ++ pm_runtime_put_noidle(&slave->dev); + return ret; ++ } + + ret = sdw_nread_no_pm(slave, addr, count, val); + +@@ -595,9 +597,11 @@ int sdw_nwrite(struct sdw_slave *slave, u32 addr, size_t count, const u8 *val) + { + int ret; + +- ret = pm_runtime_resume_and_get(&slave->dev); +- if (ret < 0 && ret != -EACCES) ++ ret = pm_runtime_get_sync(&slave->dev); ++ if (ret < 0 && ret != -EACCES) { ++ pm_runtime_put_noidle(&slave->dev); + return ret; ++ } + + ret = sdw_nwrite_no_pm(slave, addr, count, val); + +@@ -1565,9 +1569,10 @@ static int sdw_handle_slave_alerts(struct sdw_slave *slave) + + sdw_modify_slave_status(slave, SDW_SLAVE_ALERT); + +- ret = pm_runtime_resume_and_get(&slave->dev); ++ ret = pm_runtime_get_sync(&slave->dev); + if (ret < 0 && ret != -EACCES) { + dev_err(&slave->dev, "Failed to resume device: %d\n", ret); ++ pm_runtime_put_noidle(&slave->dev); + return ret; + } + +-- +2.39.2 + diff --git a/queue-6.1/soundwire-dmi-quirks-add-remapping-for-intel-rooks-c.patch b/queue-6.1/soundwire-dmi-quirks-add-remapping-for-intel-rooks-c.patch new file mode 100644 index 00000000000..61aa82a0989 --- /dev/null +++ b/queue-6.1/soundwire-dmi-quirks-add-remapping-for-intel-rooks-c.patch @@ -0,0 +1,73 @@ +From b1be588746f8273c131c01d67bd36b739f5f5abc Mon Sep 17 00:00:00 2001 +From: Sasha Levin +Date: Tue, 14 Mar 2023 17:06:18 +0800 +Subject: soundwire: dmi-quirks: add remapping for Intel 'Rooks County' NUC M15 +MIME-Version: 1.0 +Content-Type: text/plain; charset=UTF-8 +Content-Transfer-Encoding: 8bit + +From: Eugene Huang + +[ Upstream commit 01b33e284ca28cc977bdcfb23be2c719f2139175 ] + +Same DSDT problem as the HP Omen 16-k0005TX, except rt1316 amp is on +link2. + +Link: https://github.com/thesofproject/linux/issues/4088 +Signed-off-by: Eugene Huang +Reviewed-by: Pierre-Louis Bossart +Reviewed-by: Péter Ujfalusi +Signed-off-by: Bard Liao +Link: https://lore.kernel.org/r/20230314090618.498716-1-yung-chuan.liao@linux.intel.com +Signed-off-by: Vinod Koul +Signed-off-by: Sasha Levin +--- + drivers/soundwire/dmi-quirks.c | 25 +++++++++++++++++++++++++ + 1 file changed, 25 insertions(+) + +diff --git a/drivers/soundwire/dmi-quirks.c b/drivers/soundwire/dmi-quirks.c +index 7969881f126dc..58ea013fa918a 100644 +--- a/drivers/soundwire/dmi-quirks.c ++++ b/drivers/soundwire/dmi-quirks.c +@@ -73,6 +73,23 @@ static const struct adr_remap hp_omen_16[] = { + {} + }; + ++/* ++ * Intel NUC M15 LAPRC510 and LAPRC710 ++ */ ++static const struct adr_remap intel_rooks_county[] = { ++ /* rt711-sdca on link0 */ ++ { ++ 0x000020025d071100ull, ++ 0x000030025d071101ull ++ }, ++ /* rt1316-sdca on link2 */ ++ { ++ 0x000120025d071100ull, ++ 0x000230025d131601ull ++ }, ++ {} ++}; ++ + static const struct dmi_system_id adr_remap_quirk_table[] = { + /* TGL devices */ + { +@@ -98,6 +115,14 @@ static const struct dmi_system_id adr_remap_quirk_table[] = { + }, + .driver_data = (void *)intel_tgl_bios, + }, ++ { ++ /* quirk used for NUC15 'Rooks County' LAPRC510 and LAPRC710 skews */ ++ .matches = { ++ DMI_MATCH(DMI_SYS_VENDOR, "Intel(R) Client Systems"), ++ DMI_MATCH(DMI_PRODUCT_NAME, "LAPRC"), ++ }, ++ .driver_data = (void *)intel_rooks_county, ++ }, + { + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "Dell Inc"), +-- +2.39.2 + diff --git a/queue-6.1/soundwire-qcom-gracefully-handle-too-many-ports-in-d.patch b/queue-6.1/soundwire-qcom-gracefully-handle-too-many-ports-in-d.patch new file mode 100644 index 00000000000..061925c9116 --- /dev/null +++ b/queue-6.1/soundwire-qcom-gracefully-handle-too-many-ports-in-d.patch @@ -0,0 +1,50 @@ +From da6cac970293e781a724982351f39aa726627564 Mon Sep 17 00:00:00 2001 +From: Sasha Levin +Date: Wed, 22 Feb 2023 15:44:12 +0100 +Subject: soundwire: qcom: gracefully handle too many ports in DT + +From: Krzysztof Kozlowski + +[ Upstream commit 2367e0ecb498764e95cfda691ff0828f7d25f9a4 ] + +There are two issues related to the number of ports coming from +Devicetree when exceeding in total QCOM_SDW_MAX_PORTS.
