2020-03-09spi: imx: Use dynamic bursts only when bits_per_word is 8, 16 or 32Maxime Chevallier
commit 2801b2f5fad3d1e9ea0ac8484584051071065645 upstream The dynamic bursts mode allows to group together multiple words into a single burst. To do so, it's necessary that words can be packed into the 32-bits FIFO entries, so we can't allow using this mode with bit_per_words different to 8, 16 or 32. This prevents shitfing out extra clock ticks for transfers with bit_per_word values not aligned on 8 bits. With that , we are sure that only the correct number of bits is shifted out at each transfer, so we don't need to mask out the remaining parts of the words.

2020-02-12random: try to actively add entropy rather than passively wait for itLinus Torvalds
For 5.3 we had to revert a nice ext4 IO pattern improvement, because it caused a bootup regression due to lack of entropy at bootup together with arguably broken user space that was asking for secure random numbers when it really didn't need to. See commit 72dbcf721566 (Revert "ext4: make __ext4_get_inode_loc plug"). This aims to solve the issue by actively generating entropy noise using the CPU cycle counter when waiting for the random number generator to initialize. This only works when you have a high-frequency time stamp counter available, but that's the case on all modern x86 CPU's, and on most other modern CPU's too. What we do is to generate jitter entropy from the CPU cycle counter under a somewhat complex load: calling the scheduler while also guaranteeing a certain amount of timing noise by also triggering a timer. I'm sure we can tweak this, and that people will want to look at other alternatives, but there's been a number of papers written on jitter entropy, and this should really be fairly conservative by crediting one bit of entropy for every timer-induced jump in the cycle counter. Not because the timer itself would be all that unpredictable, but because the interaction between the timer and the loop is going to be. Even if (and perhaps particularly if) the timer actually happens on another CPU, the cacheline interaction between the loop that reads the cycle counter and the timer itself firing is going to add perturbations to the cycle counter values that get mixed into the entropy pool. As Thomas pointed out, with a modern out-of-order CPU, even quite simple loops show a fair amount of hard-to-predict timing variability even in the absense of external interrupts. But this tries to take that further by actually having a fairly complex interaction. This is not going to solve the entropy issue for architectures that have no CPU cycle counter, but it's not clear how (and if) that is solvable, and the hardware in question is largely starting to be irrelevant. And by doing this we can at least avoid some of the even more contentious approaches (like making the entropy waiting time out in order to avoid the possibly unbounded waiting).

2020-02-12dma: pxp: enable pxp clocks before soft resetPhilippe Schenker
pxp_soft_reset is writing to registers that are not clocked and then resulting in a lockup. Interestingly I could only see this behaviour when starting a kernel using kexec. This could have something to do with how u-boot enables clocks on a regular boot. In this commit this gets fixed with enabling the clocks before doing a pxp_soft_reset.

2020-02-12rpmsg: virtio rpmsg: Add RPMsg char driver supportIgor Opaniuk
virtio rpmsg was not implemented to use RPMsg char driver. Each virtio ns announcement will create a new RPMsg device which is supposed to bound to a RPMsg driver. It doesn't support dynamic endpoints with name service per RPMsg device. With RPMsg char driver, you can have multiple endpoints per RPMsg device. Here is the change from this patch: * Introduce a macro to indicate if want to use RPMsg char driver for virtio RPMsg. The RPMsg device can either be bounded to a simple RPMsg driver or the RPMsg char driver. * Create Virtio RPMsg char device when the virtio RPMsg driver is probed. * when there is a remote service announced, keep it in the virtio proc remote services list. * when there is an endpoint created, bind it to a remote service from the remote services list. If the service doesn't exist yet, create one and mark the service address as ANY. That patch ported to our 4.14 kernel + additional fixes added [1]. Example of usage from userspace app: ``` char data_buf [] = {'a', 'b', 'c', 'd', '\0'}; struct rpmsg_endpoint_info ept_info = {"rpmsg-openamp-demo-channel", 0x2, 0x1}; int fd = open("/dev/rpmsg_ctrl0", O_RDWR); /* create endpoint interface */ ioctl(fd, RPMSG_CREATE_EPT_IOCTL, &ept_info); /* create endpoint */ int fd_ept = open("/dev/rpmsg0", O_RDWR); /* receive data from remote device */ read(fd_ept, &data_buf, sizeof(data_buf)); /* send data to remote device */ write(fd_ept, &data_buf, sizeof(data_buf)); /* destroy endpoint */ ioctl(fd_ept, RPMSG_DESTROY_EPT_IOCTL); close(fd_ept); close(fd); ``` [1] https://patchwork.kernel.org/patch/10145779/ Signed-off-by: Wendy Liang <jliang@xilinx.com> Signed-off-by: Igor Opaniuk <igor.opaniuk@toradex.com>
