![]() ![]() I am reading serial flash data using readbuffer using the example bootloader from Raul's awesome post but I keep seeing the same flips so my kernel is not booting. I am still having issues it seems with writing the kernel binary to flash here for loading the kernel bin file from flash and its driving me crazy.

The cursor stops blinking after 20s but I dont see the kernel load. I then went ahead and built a device_tree setup and copied this to the Linux kernel tree and built the kernel using a hopefully correct defconfig file but after downloading using xmd I see no output on the console after I start the processor at the correct address. All tests pass, memory tests, hello world etc, all display to the console. ath10k: protect ath10k_htt_rx_ring_free with rx_ring.Built a Microblaze design for Arty and set the serial to 115200. net: phy: xgmiitorgmii: Check read_status results ASoC: qdsp6: qdafe: fix some off by one bugs media: tm6000: add error handling for dvb_register_adapter staging: mt7621-dts: Fix remaining pcie warnings serial: pxa: Fix an error handling path in 'serial_pxa_probe()' ![]() arm64: dts: renesas: salvator-common: Fix adv7482 decimal unit addresses drivers/tty: add error handling for pcmcia_loop_config staging: mt7621-eth: Fix memory leak in mtk_add_mac() error path media: ov772x: allow i2c controllers without I2C_FUNC_PROTOCOL_MANGLING staging: android: ashmem: Fix mmap size validation media: ov772x: add checks for register read errors iommu/msm: Don't call iommu_device_ initial data 6lowpan: iphc: reset mac_header after decompress to fix panic USB: serial: kobil_sct: fix modem-status error handling Bluetooth: Add a new Realtek 8723DE ID 0bda:b009 iommu/amd: make sure TLB to be flushed before IOVA freed power: vexpress: fix corruption in notifier registration serial: sh-sci: Stop RX FIFO timer during port shutdown misc: sram: enable clock before registering regions power: supply: axp288_charger: Fix initial constant_ charge_ current value staging: rts5208: fix missing error check on call to rtsx_write_register x86/numa_emulation: Fix emulated- to-physical node mapping siox: don't create a thread without starting it vmci: type promotion bug in qp_host_ get_user_ memory( ) misc: ibmvmc: Use GFP_ATOMIC under spin lock tsl2550: fix lux1_input error in low light iio: adc: ina2xx: avoid kthread_stop() with stale task_struct crypto: skcipher - Fix -Wstringop- truncation warnings ![]() * Cosmic update: v4.18.12 upstream stable release (LP: #1796139) This bug was fixed in the package linux - 4.18.0-9.10 (while true do echo 3 > /proc/sys/ vm/drop_ caches sleep 1 done)&Ĥ) start multiple parallel reader for data set at same timeįind /mnt/nfs -type f | xargs -P 80 cat > /dev/null &ĥ) finally check using cat /proc/fs/ fscache/ stats | grep -i pages įree -h, cat /proc/meminfo and page-types -r -b lru The fix is straightforward, to decrement the reference when error is encounterd.Ī user has tested the fix using following method for 12+ hrs.ġ) mkdir -p /mnt/nfs mount -o vers=3,fsc :/export /mnt/nfsĢ) create 10000 files of 2.8MB in a NFS mount.ģ) start a thread to simulate heavy VM presssure During the error handling cachefiles does not cleanup the reference on backing page, leading to page leak. This results in one of the thread finding that a page for the backing file or netfs file is already in the radix tree. This can happen because two applications can be reading same page from a single mount, two threads can be trying to read the backing page at same time. In a heavily loaded system where the system pagecache is nearing memory limits and fscache is enabled, pages can be leaked by fscache while trying read pages from cachefiles backend. ![]()
