mtk-20170518/target/linux/x86/generic, branch v17.01.4 MTK 20170518 : Mediatek SDK based on OpenWRT Barrier Breaker x86: Fix xen serial console by removing conflicting PATA driver 2017-10-16T07:43:35+00:00 Baptiste Jonglez git@bitsofnetworks.org 2017-07-15T20:57:54+00:00 da0219ed9f990e5a951197c2c9c6a916d17109d1 The Xen serial console has been broken since the xen_domu subtarget was merged in the generic x86 subtarget (commits 296772f9 and b36e24f3). The reason for the broken serial console seems to be an IRQ conflict between the serial console driver and the PATA_LEGACY driver: [ 1.330125] genirq: Flags mismatch irq 8. 00000000 (hvc_console) vs. 00000000 (platform[pata_legacy.4]) [ 1.330134] hvc_open: request_irq failed with rc -16. [ 1.330148] Warning: unable to open an initial console. Just drop the PATA_LEGACY driver from the x86/generic and x86_64 subtargets, since this driver is marked experimental and only supports very old ISA devices anyway. It is still included in the x86/legacy subtarget where it rightfully belongs. Fixes: FS#787 Signed-off-by: Baptiste Jonglez <git@bitsofnetworks.org> 
The Xen serial console has been broken since the xen_domu subtarget
was merged in the generic x86 subtarget (commits 296772f9 and b36e24f3).

The reason for the broken serial console seems to be an IRQ conflict
between the serial console driver and the PATA_LEGACY driver:

[    1.330125] genirq: Flags mismatch irq 8. 00000000 (hvc_console) vs. 00000000 (platform[pata_legacy.4])
[    1.330134] hvc_open: request_irq failed with rc -16.
[    1.330148] Warning: unable to open an initial console.

Just drop the PATA_LEGACY driver from the x86/generic and x86_64
subtargets, since this driver is marked experimental and only supports
very old ISA devices anyway.  It is still included in the x86/legacy
subtarget where it rightfully belongs.

Fixes: FS#787

x86/generic: use HIGHMEM64G instead of HIGHMEM4G to fix PAE and Xen 2017-10-16T07:40:26+00:00 Baptiste Jonglez git@bitsofnetworks.org 2017-07-15T20:57:53+00:00 f52b404aeea328b4e021a245c640ed3b0e095fa8 This is a backport of 641a65fd062987a456216cc4fa91ff2910528261 in master. This change re-enables PAE for the 32-bit x86 subtarget, which is interesting in its own right but also necessary for Xen support. Commit af1d1ebd ("x86: enable 4G high memory support for generic (32bit) subtarget") inadvertently disabled both PAE and Xen support.
