[PATCH v4] mtd: spear_smi: Fix Write Burst mode

by Miquel Raynal

Any write with either dd or flashcp to a device driven by the spear_smi.c driver will pass through the spear_smi_cpy_toio() function. This function will get called for chunks of up to 256 bytes. If the amount of data is smaller, we may have a problem if the data length is not 4-byte aligned. In this situation, the kernel panics during the memcpy: # dd if=/dev/urandom bs=1001 count=1 of=/dev/mtd6 spear_smi_cpy_toio [620] dest c9070000, src c7be8800, len 256 spear_smi_cpy_toio [620] dest c9070100, src c7be8900, len 256 spear_smi_cpy_toio [620] dest c9070200, src c7be8a00, len 256 spear_smi_cpy_toio [620] dest c9070300, src c7be8b00, len 233 Unhandled fault: external abort on non-linefetch (0x808) at 0xc90703e8 [...] PC is at memcpy+0xcc/0x330 The above error occurs because the implementation of memcpy_toio() tries to optimize the number of I/O by writing 4 bytes at a time as much as possible, until there are less than 4 bytes left and then switches to word or byte writes. Unfortunately, the specification states about the Write Burst mode: "the next AHB Write request should point to the next incremented address and should have the same size (byte, half-word or word)" This means ARM architecture implementation of memcpy_toio() cannot reliably be used blindly here. Workaround this situation by update the write path to stick to byte access when the burst length is not multiple of 4.

Changes in v2: ============== * This time I think the patch really fixes the problem: we use a memcpy_toio_b() function to force byte access only when needed. We don't use the _memcpy_toio() helper anymore as the fact that it is doing byte access is purely an implementation detail and is not part of the API, while the function is also flagged as "should be optimized". * One could argue that potentially memcpy_toio() does not ensure by design 4-bytes access only but I think it is good enough to use it in this case as the ARM implementation of this function is already extensively optimized. I also find clearer to use it than adding my own spear_smi_mempy_toio_l(). Please tell me if you disagree with this. * The volatile keyword has been taken voluntarily from the _memcpy_toio() implementation I was about to use previously. drivers/mtd/devices/spear_smi.c | 38 ++++++++++++++++++++++++++++++++- 1 file changed, 37 insertions(+), 1 deletion(-) diff --git a/drivers/mtd/devices/spear_smi.c b/drivers/mtd/devices/spear_smi.c index 986f81d2f93e..47ad0766affa 100644 --- a/drivers/mtd/devices/spear_smi.c +++ b/drivers/mtd/devices/spear_smi.c @@ -592,6 +592,26 @@ static int spear_mtd_read(struct mtd_info *mtd, loff_t from, size_t len, return 0; } +/* + * The purpose of this function is to ensure a memcpy_toio() with byte writes + * only.

We have observed such kind of livelock on a Marvell cn96xx board(24 cpus) when heavily using the dump_stack() in a kprobe handler. Actually we can let the competitors to wait for the releasing of the lock before jumping to atomic_cmpxchg(). This will definitely mitigate the thundering herd problem.

[PATCH] etnaviv: fix dumping of iommuv2

by Christian Gmeiner

etnaviv_iommuv2_dump_size(..) returns the number of PTE * SZ_4K but etnaviv_iommuv2_dump(..) increments buf pointer even if there is no PTE. This results in a bad buf pointer which gets used for memcpy(..).

[PATCH v2] arm64: cpufeature: Enable Qualcomm Falkor/Kryo errata 1003

by Bjorn Andersson

With the introduction of 'cce360b54ce6 ("arm64: capabilities: Filter the entries based on a given mask")' the Qualcomm Falkor/Kryo errata 1003 is no long applied. The result of not applying errata 1003 is that MSM8996 runs into various RCU stalls and fails to boot most of the times. Give 1003 a "type" to ensure they are not filtered out in update_cpu_capabilities(). Fixes: cce360b54ce6 ("arm64: capabilities: Filter the entries based on a given mask") Cc: stable(a)vger.kernel.org Reported-by: Mark Brown <broonie(a)kernel.org> Suggested-by: Will Deacon <will(a)kernel.org> Signed-off-by: Bjorn Andersson <bjorn.andersson(a)linaro.org> --- Changes since v1: - s/ARM64_CPUCAP_SCOPE_LOCAL_CPU/ARM64_CPUCAP_LOCAL_CPU_ERRATUM/ - Dropped 1009 "fix" as it already had a type from ERRATA_MIDR_RANGE_LIST() arch/arm64/kernel/cpu_errata.c | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/kernel/cpu_errata.c b/arch/arm64/kernel/cpu_errata.c index df9465120e2f..3facd5ca52ed 100644 --- a/arch/arm64/kernel/cpu_errata.c +++ b/arch/arm64/kernel/cpu_errata.c @@ -780,6 +780,7 @@ const struct arm64_cpu_capabilities arm64_errata[] = { { .desc = "Qualcomm Technologies Falkor/Kryo erratum 1003", .capability = ARM64_WORKAROUND_QCOM_FALKOR_E1003, + .type = ARM64_CPUCAP_LOCAL_CPU_ERRATUM, .matches = cpucap_multi_entry_cap_matches, .match_list = qcom_erratum_1003_list, }, -- 2.23.0
