While MXM3 pin 37 aka WAKE1_MICO is pulled up with 4.7 K on the Apalis Evaluation board and 100 K on the Ixora carrier board a custom carrier board may leave it floating which may cause an unintended high interrupt load on the default wake-up key with which may cause a lower CPU performance.

2016-03-22ARM: 8429/1: disable GCC SRA optimizationArd Biesheuvel
While working on the 32-bit ARM port of UEFI, I noticed a strange corruption in the kernel log. The following snprintf() statement (in drivers/firmware/efi/efi.c:efi_md_typeattr_format()) snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]", was producing the following output in the log: | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | | | | |UC] |RUN| | | | | | | |UC] As it turns out, this is caused by incorrect code being emitted for the string() function in lib/vsprintf.c. The following code if (!(spec.flags & LEFT)) { while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } } for (i = 0; i < len; ++i) { if (buf < end) *buf = *s; ++buf; ++s; } while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } when called with len == 0, triggers an issue in the GCC SRA optimization pass (Scalar Replacement of Aggregates), which handles promotion of signed struct members incorrectly. This is a known but as yet unresolved issue. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular case, it is causing the second while loop to be executed erroneously a single time, causing the additional space characters to be printed. So disable the optimization by passing -fno-ipa-sra.

With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the wrong thing (emits code for an externally linkable version of the inline function).

2016-03-21apalis_t30: ixora: optionally support leds, switch, foff and wdisableMarcel Ziswiler
The Ixora carrier board has a few MXM3 pins repurposed as follows: Functionality MXM3 Pin LED4_RED 146 LED4_GREEN 162 LED5_RED 156 LED5_GREEN 152 PCIE1_WDISABLE_N 144 SW3 160 UART2_3_RS232_FOFF_N 164 This patch allows uncommenting an IXORA define in the board header file in order to make use of those repurposed pins. Please note that those pins are usually used for the 8-bit MMC/SD slot aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes the output driver behaviour in a way preventing any regular GPIO use. This patch therefore explicitly does not register the SDHCI driver on this controller instance in the Ixora case to avoid this.

2015-09-26apalis/colibri_t30: usb: fix performance regressionMarcel Ziswiler
Unfortunately that utmi_phy_remotewake_detected() function gets called one too many times even quite continuously during data transfers and putting an mdelay() in there has a rather adverse effect on the overall system performance including of course degrading USB transfer speeds. Moving the system lock-up avoidance hack further down into the if clause improves the performance again as this typically is only ever evaluated once upon actually plugging something in behind a hub. This fixes a performance regression introduced by the following commit: apalis/colibri_t30: usb: fix low-speed issue hack 629b91fa046df5213ed3312d2e2b8683e6bdd70c
