1 | From: Guenter Roeck <linux@roeck-us.net> | ||
2 | 1 | ||
3 | The sabrelite machine model used by qemu-system-arm is based on the | ||
4 | Freescale/NXP i.MX6Q processor. This SoC has an on-board ethernet | ||
5 | controller which is supported in QEMU using the imx_fec.c module | ||
6 | (actually called imx.enet for this model.) | ||
7 | |||
8 | The include/hw/arm/fsm-imx6.h file defines the interrupt vectors for the | ||
9 | imx.enet device like this: | ||
10 | |||
11 | #define FSL_IMX6_ENET_MAC_1588_IRQ 118 | ||
12 | #define FSL_IMX6_ENET_MAC_IRQ 119 | ||
13 | |||
14 | According to https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf, | ||
15 | page 225, in Table 3-1. ARM Cortex A9 domain interrupt summary, | ||
16 | interrupts are as follows. | ||
17 | |||
18 | 150 ENET MAC 0 IRQ | ||
19 | 151 ENET MAC 0 1588 Timer interrupt | ||
20 | |||
21 | where | ||
22 | |||
23 | 150 - 32 == 118 | ||
24 | 151 - 32 == 119 | ||
25 | |||
26 | In other words, the vector definitions in the fsl-imx6.h file are reversed. | ||
27 | |||
28 | Fixing the interrupts alone causes problems with older Linux kernels: | ||
29 | The Ethernet interface will fail to probe with Linux v4.9 and earlier. | ||
30 | Linux v4.1 and earlier will crash due to a bug in Ethernet driver probe | ||
31 | error handling. This is a Linux kernel problem, not a qemu problem: | ||
32 | the Linux kernel only worked by accident since it requested both interrupts. | ||
33 | |||
34 | For backward compatibility, generate the Ethernet interrupt on both interrupt | ||
35 | lines. This was shown to work from all Linux kernel releases starting with | ||
36 | v3.16. | ||

7 | the command line to use -cpu to ask for a different kind of | ||
8 | CPU than the SoC supports. This was never a supported thing to | ||
9 | do anyway; we were just not sanity-checking the command line. | ||
10 | |||
11 | This does require us to only build the bcm2837 object on | ||
12 | TARGET_AARCH64 configs, since otherwise it won't instantiate | ||
13 | due to the missing cortex-a53 device and "make check" will fail. | ||

1 | From: Andrey Smirnov <andrew.smirnov@gmail.com> | 1 | Add a new script to automate the process of running the Coverity |
---|---|---|---|
2 | 2 | Scan build tools and uploading the resulting tarball to the | |
3 | Code of imx_update() is slightly confusing since the "flags" variable | 3 | website. |
4 | doesn't really corespond to anything in real hardware and server as a | 4 | |
5 | kitchensink accumulating events normally reported via USR1 and USR2 | 5 | This is intended eventually to be driven from Travis, |
6 | registers. | 6 | but it can be run locally, if you are a maintainer of the |
7 | 7 | QEMU project on the Coverity Scan website and have the secret | |
8 | Change the code to explicitly evaluate state of interrupts reported | 8 | upload token. |
9 | via USR1 and USR2 against corresponding masking bits and use the to | 9 | |
10 | detemine if IRQ line should be asserted or not. | 10 | The script must be run on a Fedora 30 system. Support for using a |
11 | 11 | Docker container is added in a following commit. | |
12 | NOTE: Check for UTS1_TXEMPTY being set has been dropped for two | 12 | |
13 | reasons: | 13 | Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> |
14 | |||
15 | 1. Emulation code implements a single character FIFO, so this flag | ||
16 | will always be set since characters are trasmitted as a part of | ||
17 | the code emulating "push" into the FIFO | ||
18 | |||
19 | 2. imx_update() is really just a function doing ORing and maksing | ||
20 | of reported events, so checking for UTS1_TXEMPTY should happen, | ||
21 | if it's ever really needed should probably happen outside of | ||
22 | it. | ||

10 | and a 1.5.x Sphinx fails with | ||
11 | docs/system/invocation.rst:544: WARNING: Malformed option description '[enable=]PATTERN', should look like "opt", "-opt | ||
12 | args", "--opt args", "/opt args" or "+opt args" | ||
13 | |||
14 | Update our needs_sphinx setting to indicate that we require at least | ||
15 | 1.6. This will allow configure to fall back to "don't build the | ||
16 | docs" rather than causing the build to fail entirely, which is | ||
17 | probably what most users building on a host old enough to have such | ||
18 | an old Sphinx would want; if they do want the docs then they'll have | ||
19 | a useful indication of what they need to do (upgrade Sphinx!) rather | ||
20 | than a confusing error message. | ||
21 | |||
22 | In theory our distro support policy would suggest that we should | ||
23 | support building on the Sphinx shipped in those distros, but: | ||
24 | * EPEL7 has Sphinx 1.2.3 (which we've never supported!) | ||
25 | * Debian Stretch has Sphinx 1.4.8 | ||
26 | |||
27 | Trying to get our docs to work with Sphinx 1.4 is not tractable | ||
28 | for the 5.0 release and I'm not sure it's worthwhile effort anyway; | ||
29 | at least with this change the build as a whole now succeeds. | ||
30 | |||
31 | Thanks to John Snow for doing the investigation and testing to | ||
32 | confirm what Sphinx versions fail in what ways and what distros | ||
33 | shipped what. | ||
