CIF_ISP_PIC_SIZE_ERROR error on rkisp10 #166
Comments
|
have you resolved this problem? I met the same promble with nanopi-neo4,CIF_PIC_SIZE_ERROR，and my camera output image is not right |
|
@davidmarshalla |
thanks for giving advice, but i use rkisp instead of cif_isp , so is there any other method? |

[ Upstream commit c784be4 ] The calls to arch_add_memory()/arch_remove_memory() are always made with the read-side cpu_hotplug_lock acquired via memory_hotplug_begin(). On pSeries, arch_add_memory()/arch_remove_memory() eventually call resize_hpt() which in turn calls stop_machine() which acquires the read-side cpu_hotplug_lock again, thereby resulting in the recursive acquisition of this lock. In the absence of CONFIG_PROVE_LOCKING, we hadn't observed a system lockup during a memory hotplug operation because cpus_read_lock() is a per-cpu rwsem read, which, in the fast-path (in the absence of the writer, which in our case is a CPU-hotplug operation) simply increments the read_count on the semaphore. Thus a recursive read in the fast-path doesn't cause any problems. However, we can hit this problem in practice if there is a concurrent CPU-Hotplug operation in progress which is waiting to acquire the write-side of the lock. This will cause the second recursive read to block until the writer finishes. While the writer is blocked since the first read holds the lock. Thus both the reader as well as the writers fail to make any progress thereby blocking both CPU-Hotplug as well as Memory Hotplug operations.

commit 2f37249 upstream. The IPA BCM resource ("IP0") on sc7180 was moved to the clk-rpmh driver in commit bcd63d2 ("clk: qcom: rpmh: Add IPA clock for SC7180") and modeled as a clk, but this interconnect driver still had it modeled as an interconnect. This was mostly OK because nobody used the interconnect definition, until the interconnect framework started dropping bandwidth requests on interconnects that aren't used via the sync_state callback in commit 7d3b0b0 ("interconnect: qcom: Use icc_sync_state"). Once that patch was applied the IP0 resource was going to be controlled from two places, the clk framework and the interconnect framework. Even then, things were probably going to be OK, because commit b95b668 ("interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregate") was needed to actually drop bandwidth requests on unused interconnects, of which the IPA was one of the interconnect that wasn't getting dropped to zero. Combining the three commits together leads to bad behavior where the interconnect framework is disabling the IP0 resource because it has no users while the clk framework thinks the IP0 resource is on because the only user, the IPA driver, has turned it on via clk_prepare_enable(). Depending on when sync_state is called, we can get into a situation like below: IPA driver probes IPA driver gets notified modem started runtime PM get() IPA clk enabled -> IP0 resource is ON sync_state runs interconnect zeroes out the IP0 resource -> IP0 resource is off IPA driver tries to access a register and blows up The crash is an unclocked access that manifest as an SError.

If a relocatable kernel is loaded at an address that is not 2MB aligned and told not to relocate to zero, the kernel can crash due to mark_rodata_ro() incorrectly changing some read-write data to read-only.
