Re: Exactly how slow is Fedora 27 on an RP3 ? dnf update takes hours ?
by linux guy
I removed the suspect SD card from the RPi3 and tested it in my laptop.
# hdparm -Tt /dev/mmcblk0
/dev/mmcblk0:
Timing cached reads: 15750 MB in 2.00 seconds = 7893.74 MB/sec
Timing buffered disk reads: 88 MB in 3.05 seconds = 28.82 MB/sec <---
This was 365 kB/sec in the RPi3.
It seems to test OK in the laptop. Bad connection in the RPi3 ?
So I prepared a second class 10 SD card with the same image. I tested it in
the laptop that I used to prepare it.
# hdparm -Tt /dev/mmcblk0
/dev/mmcblk0:
Timing cached reads: 15908 MB in 2.00 seconds = 7973.32 MB/sec
Timing buffered disk reads: 54 MB in 3.05 seconds = 17.71 MB/sec
The second SD is actually slower to read than the first one, in the
laptop. 28.82 versus 17.71 MB/sec
I booted the 2nd SD card in the RPi3.
# hdparm -Tt /dev/mmcblk0
/dev/mmcblk0:
Timing cached reads: 816 MB in 2.00 seconds 408.21 MB/sec
Timing buffered disk reads: 66 MB in 3.03 seconds = 21.81 MB/sec <---
Faster than it was in the laptop !
#time dnf update - install 32 packages, update 275, just like last time
I ran #time dnf update and stopped it at 47 packages.
real: 30m46.181s
user: 0.00s
sys: 0m.020s
I retested the SD card and got the same read speeds as above.

The 4.15 kernel rebase on stable releases
by Peter Robinson
Hi All,
Just a heads up that the 4.15 kernel is headed to stable releases.
I did a bunch of testing over the weekend and fixed up a bunch of
issues, added some minor enhancements across a number of platforms.
There is a kernel-4.15.2-301.fc27 build [1] which had all those fixes
for people to test, I expect a 4.15.3 kernel going to updates-testing
later today or tomorrow.
A few notes for the fixes I added:
* fixed cpufreq/thermal on i.MX6 (thanks kwizart for upstream fix)
* Crypto/rng engine on some AllWinner devices now loads/works
(A10/A143/A20 at least, I suspect more will come with later kernels)
* Exynos 5 USB-3 issue should now be fixed once and for all (I hope)
* A bunch of improvements for monitor detection on the Raspberry Pi
* Ethernet driver more stable on AllWInner A64/H5 platforms (like Pine64)
* Numerous other upstream fixes improvements that headed upstream
* 4.15.3 (not in the build above) will include aarch64 fixes for
Spectre/Meltdown.
So please test and feel free to reply to this thread with any new
issues you see with the 4.15 series, or any positive results.

Using generic tuning form armhfp
by Florian Weimer
GCC offers a generic tuning option for Arm these days, but we select
-mtune=cortex-8a instead.
Is this still a good choice?
Thanks,
Florian
