2020-05-08vppinfra: set explicit found in search_free_list loopSteven Luong1-2/+6
While https://gerrit.fd.io/r/c/vpp/+/26948 fixed avoid using -1 to index into h->free_lists[b][l] by changing the loop counter, the check for the value of the loop counter (l < 0) cannot be trusted to decide whether we've found a large enough object within the bin or not. When the loop is terminated, the value of the variable l could be ambiguous if it equals to 0 and it is never less than 0, ie, when we bail out of the loop, we don't know if it was due to the breaking out of the condition in if ((s = f_size - size) >= 0) break; or while (l > 0); The fix is to explicitly set a variable when we have found a large enough object inside the loop to be used to test whether the loop was prematurely terminated (found == 1) or the loop just ran exhausted (found == 0) Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I0161813fbd44dcba8982a767eac2e0930e9d77e3
2020-05-08vppinfra: fix u32x4_byte_swap on ArmLijian.Zhang1-1/+1
Fix the endianness conversion function u32x4_byte_swap() on Arm. Here's an example of using this function with and without the fix. This issue is seen using Mellanox NIC RDMA driver on Arm servers. The packet length cannot be parsed correctly. Testing code: u32x4 s = {0x12345678, 0x23456789, 0x3456789a, 0x456789ab}; u32x4 ss = u32x4_byte_swap (s); Without the code change: (gdb) p /x s $1 = {0x12345678, 0x23456789, 0x3456789a, 0x456789ab} (gdb) p /x ss $2 = {0x23456789, 0x12345678, 0x456789ab, 0x3456789a} With the code change: (gdb) p /x s $3 = {0x12345678, 0x23456789, 0x3456789a, 0x456789ab} (gdb) p /x ss $4 = {0x78563412, 0x89674523, 0x9a785634, 0xab896745} Type: fix Change-Id: Ie5f263e94331783940e7c00397092a64e4fc4279 Signed-off-by: Lijian Zhang <Lijian.Zhang@arm.com> Reviewed-by: Jieqiang Wang <Jieqiang.Wang@arm.com> Reviewed-by: Govindarajan Mohandoss <Govindarajan.Mohandoss@arm.com>
2020-05-07vppinfra: loop counter off by 1 in search_free_list()Steven Luong1-1/+1
In search_free_list(), we have this do while loop. do { l--; f_index = h->free_lists[b][l]; f = elt_at (h, f_index); f_size = heap_elt_size (v, f); if ((s = f_size - size) >= 0) break; } while (l >= 0); When (l == 0), we still go back up to execute l--. Then l become -1. The next statement is we index h->free_lists[b][-1]. After that, elt_at() would probably cause a crash in the ASSERT.

Deal with arbitrary kernel reference time changes: for example, yanking the kernel reference clock back to a time before vpp started. Best practice involves aligning the kernel reference clock with reality prior to starting apps which use 10us granularity timers. Compute change in the reference and cpu clocks. Recompute the vpp start time reference and and total cpu clock count, using the current clock tick rate. Next, compute a new clock rate sample. If the sample seems sane, factor it into the exponentially smoothed clock rate and recalculate total cpu ticks based on the new clock rate.

2020-02-25svm: refactor fifoFlorin Coras2-10/+21
Type: refactor Switch from a wrapped byte space to a "continuous" one wherein fifo chunks are appended to the fifo as more data is enqueued and chunks are removed as data is dequeued. The fifo is still subject to a maximum size, i.e., maximum number of bytes that can be enqueued, so the max number of chunks associated to the fifo is also constrained. When enqueueing data, which must fit within the available free space, if not enough "supporting" chunk memory is available, the fifo asks the fifo segment for enough chunk memory to ensure that the write can succeed. To avoid allocating large amounts of small chunks due to small writes, if possible, the size of the chunks requested is lower capped by min_alloc. When dequeuing data, all the chunks that have been completely drained, i.e., head moved beyond the chunks’ end bytes, are unlinked from the fifo and returned to the fifo segment. The one exception to this is the last chunk which is never unlinked. Change-Id: I98c1dbd9135fb79650365c7e40c29238b96cd4ee Signed-off-by: Florin Coras <fcoras@cisco.com>
